Message-ID: <593D817077A5D211A055009027285F2805E5B858@knuth.logica.co.uk>

Anyone know anything better than the code below (from John Stockton's site),
comments from [fpc-devel] , which releases cpu that will work for win95 and
win 2000? this is results so far from fpc developers...

I've noticed that although this seems to work mostly in fpc dos
program under win2000 it sometimes crashes & creates an exception...Under
win95 it _always_ seems to work, so assume win2000 problem is the dos
emulator...The code relies on the timer interupt working correctly as in
real dos. 

What is the 'best' fpc dos code (including the dos_idle pls which
does approx delay w/o wasting cputime and can be compiled with go32v2 . TIA
----------------------------------------------
{delay of n ticks releasing cpu}
procedure dlay(n : integer) ;
   const t : byte = 0 { static! saves some stack space } ;
   var timer : byte absolute $0040:$006C ;
   begin while n > 0 do begin
       t := timer ;
       repeat  asm  hlt  end  until timer<>t ;
       Dec(n) ;
       end end ;

 _If_ we decide to add something similar to the delay unit, we should
replace the halt instruction with the DOS idle call, because that many TSRs
use this one under plain DOS and it's still supported under Wxx to lower the
CPU load.

dear Pascal list,

After trying my wits with the CRT NCRT and OCRT units, I
still can not read the "Pos1" or "End" Keys from the
Terminal. All other Keys return single or double Codes just
like the old dos Terminal would with TP.

For example the "Pos1" key returns a sequence of "#27 '[' #72"
instead of the the normal "#0 #71"

Does someone know a way to get this to work right.

BTW: SuSE Linux 6.4 with KDE Terminal

Did you at least started the FPC support? Anything?

You of course understand that if any Delphi project started posting 
announces here, it would get somewhat messy? 

I.O.W. I don't have anything against your project, but, frankly, the 
announce doesn't belong here. At least, not until at least some 
serious link with FPC exist except that it is in Delphi.

Subject: [fpc-pascal]PPAS.BAT and directory paths with spaces in them
Message-ID: <200105041730.KAA36014@mx0.daemonmail.net>

Can anyone enlighten me as to the origin of PPAS.BAT ?

I'm using the released Free Pascal version 1.0.4 under Windows NT 4.0,
compiling for a Win32 target.  I use the stand-alone PPC386 compiler.

If source filename on the PPC386 command line includes a path with
spaces in it, then the linker fails and leaves file PPAS.BAT on my
disk.  For example, the command line,

  ppc386 "D:\memos\rich pasco\gentable.pas"

results in the output:

  Free Pascal Compiler version 1.0.4 [2000/12/30] for i386
  Copyright (c) 1993-2000 by Florian Klaempfl

  -: cannot open pasco\gentable.exe: No such file or directory
  gentable.pas(47,1) Warning: Error while linking
  Closing script ppas.bat
  47 Lines compiled, 0.5 sec

The linker graciously leaves PPAS.BAT on my disk for inspection.
A copy appears below.  It seems obvious that the bug is in the
fourth line: On the ldw command line, the output executable file
name should have quotes around it.

In order to fix PPAS.BAT I need to know where it came from.

This file is generated by the compiler and calls the external assembler and
linker to create an executable out of the object code FPC creates.
If this process fails, this file is left on the HD to be called by the user
to complete the linking process.

In your case the linker fails because of the whitespace character in your
path (this is partially the fault of the command shell). If you put
quotation marks in front and after the '-o' parameter it should work fine.

E.g.:
d:\pp\bin\win32\ldw.exe  -s   -b base.$$$ -o "d:\memos\rich
pasco\gentable.exe" link.res

Probably the compiler could be changed to do this automatically. Both the
call to the linker (ldw) and the actual call to the linker should be put in
quotation marks (so that fpc can be installed in directory with whitespaces
in its name too).

Regards,
    Thomas

Excerpt from the Intel docs:

The HLT instruction is a privileged instruction. When the processor is
running in protected or virtual-8086 mode, the privilege level of a program
or procedure must be 0 to execute the HLT instruction.

-> Should always exit a normal FPC program by force on NT.  (It does here)

NT uses that instruction in the idle process to lower CPU power consumption.
W9x doesn't.

    Thomas

I did some tests with W2k and it seems as if the DOS idle call is not
supported anymore (because it's not DOS the program is running). It might be
some programming mistake too though:

{delay of n ticks releasing cpu}
uses go32;

var
 timer : byte absolute $0040:$006C ;
var
 r : registers;

procedure dlay(n : integer) ;
const t : byte = 0 { static! saves some stack space } ;
begin
 while n > 0 do begin
         t := timer ;
         repeat
        // call DOS idle interrupt (my IR list from Ralf Brown says it's int
28h)
        // since the register structures' ss:sp is zero on entry the dpmi
host
        // automatically provides a real mode stack
          realintr($28, r);
         until timer<>t ;
         Dec(n) ;
        end;
end;

begin
// wait approx. 5 secs
 dlay(18*5);
end.

This program drives the cpu usage meter to 100% here.... it seems to me that
the DOS idle call is just a more elaborate way to accomplish a 'nop'.

Could anyone try with W9x ?

Btw, isn't the accuracy of the delay quite bad when using the timer IR ?
Because It only changes ~18.2 times per second giving a resolution of ~54
ms. The variance of the result is also quite high; +- a full timer tick
depending on the spot within a timer tick the timer is read first....
Although it's usually not that serious if the default delay is off a few ms
this is imho a little bit too much.

Regards,
    Thomas

Yes, but how do I put quotation marks into a file that I don't write,
but was written by the compiler for me?

That would be my request.

The interrupt comes quite rare, that's true, but the timer counters count
quite fast. You can measure in the range of microseconds if you read the
counter value as well. There is no need to reprogram the timer to do that.

Actually this was just meant as a side note and was not really the key point
imho. Never talked about reprogramming the timer; this isn't possible under
the NT-VM anyway afaik under normal circumstances (e.g. ring 3).
I'm sorry if I couldn't clearly point out what my main concern was:

The hlt instruction not being available with NT and int 28 (dos idle IR
call) not having the desired effect too (or at least I'm not using it
correctly).
Example programs which demonstrate int 28h install their own int28 IR
handler which issues a hlt instruction. This is not possible as I told you
before, and the default handler is a 'nop'.
Another IR call (Release current VM time slice, int 2Fh / 2680h) which
probably would fit too doesn't work either with W2k. (It seems to be just
another wonderful idea which never managed to become reality since it's a
DPMI 1.0 call).

Or is there any other IR / system / whatever call I don't know of ?
Additionally I'm interested if my small program I posted yesterday has the
desired effect under W9x systems (plain curiousity). Because if it does
there it might be an argument to implement it regardless of it not working
with NT. Then at least W9x could systems profit from this enhancement, can't
they ?

    Thomas

                writeln('Enter two numbers and an operator in the format');
                writeln(' number1 operator number2');
                readln( num1 ); readln( operator ); readln( num2 );

                otherwise invalid_operator := TRUE;
                if invalid_operator then
                        writeln('Invalid operator')

        end.


I have tried writing any other program, some simple calculation, and it
compiles fine, giving me error messages where necessary, but it doesn't rudely
shut down. But every time I try to compile the above it rudely shuts down. Is
there something in this code as written that is telling it to shut down??

Otherwise is not valid Free Pascal (afaik). It should be:

It's a bug in the compiler that it crashes. Please try a snapshot, that should not crash.

operator is a reserved keyword in FPC. You should replace it by some other name like
'oper'

HI Jonathan,

I think it is Lazarus which is closing down abruptly not Freepascal.
Have you tried to compile it by hand at the command prompt.

Kind regrads

Hi Stefan,

I'm still a bit confused as to what terminal/keyboard you are using.

> BTW: SuSE Linux 6.4 with KDE Terminal

Do you mean using KDE's konsole in an X session? I don't recall what keyboard 
has a Pos1 key.

The curses library returns long integer value for all keypress combinations, 
so the ncrt unit translates these into character values that readkey expects. 
Also ncurses handle #27 in a special way. If a keypress produces #27 followed 
immediately with a sequence of keys that it knows from termcap or terminfo, 
then this is treated as a combination and returned as a single integer value. 
The actual key sequence is not seen by readkey. ncrt translates a known list 
of possible values and drops the unknowns. This is probably what happens to 
your Pos1 key.

E.g. German keyboards, on the spot of the "home" key.

Wouldn't the keycodes be the same then? Is this just an xterm key mapping 
problem?

Message-ID: <593D817077A5D211A055009027285F2805E5B88E@knuth.logica.co.uk>

Tried this under w95 & it works ie gives delay, but hogs the cpu! So still
looking for way to do fpc dos delay, that works in w2000, NT & w9x...

Current status is that my original program works ok for w9x (ie gives delay
and releases cpu), but we do not have a way to do this in w2000/NT... Any
more ideas? What about using the get & put interupt vector instructions to
change the timer interupt to an _internal_ routine which counts clock
interupts and doing a dos idle in between (believe that releases cpu in
NT/w2000???).  Anyone know exactly the  the code for that would look...? 

We could then check whether it's w9x & either execute my original, or the
new w2000/nt code., and we'd have a general purpose  dos calleable approx
delay that releases cpu... John

I did some tests with W2k and it seems as if the DOS idle call is not
supported anymore (because it's not DOS the program is running). It might be
some programming mistake too though:

{delay of n ticks releasing cpu}
uses go32;

var
 timer : byte absolute $0040:$006C ;
var
 r : registers;

procedure dlay(n : integer) ;
const t : byte = 0 { static! saves some stack space } ;
begin
 while n > 0 do begin
         t := timer ;
         repeat
        // call DOS idle interrupt (my IR list from Ralf Brown says it's int
28h)
        // since the register structures' ss:sp is zero on entry the dpmi
host
        // automatically provides a real mode stack
          realintr($28, r);
         until timer<>t ;
         Dec(n) ;
        end;
end;

begin
// wait approx. 5 secs
 dlay(18*5);
end.

This program drives the cpu usage meter to 100% here.... it seems to me that
the DOS idle call is just a more elaborate way to accomplish a 'nop'.

Could anyone try with W9x ?

Btw, isn't the accuracy of the delay quite bad when using the timer IR ?
Because It only changes ~18.2 times per second giving a resolution of ~54
ms. The variance of the result is also quite high; +- a full timer tick
depending on the spot within a timer tick the timer is read first....
Although it's usually not that serious if the default delay is off a few ms
this is imho a little bit too much.

Regards,
    Thomas

Hi again,
thanks for all your input.  I'm sorry if my question seems to be
confusing.  I am having dificulty in explaining just what is not
working correctly as well as pin pointing the problem.

take this programm for example:
-------------------------------------------------------
program keys;
uses
 nCrt;

var
ch:char;
lc:char;

begin
WriteLn('Exit with 2 x ESC');
ch:=#0;
lc:=#0;
 repeat
  while not keypressed do;
   lc:=ch;
   ch:=ReadKey;
  if ch=#0 then
  begin
   Write('#0 - ');
    lc:=ch;
    ch:=ReadKey;
    Write(ord(ch));
  end else
  begin
   Write(ord(ch),' = ');
   if ch<#32 then Write(ord(ch)) else Write('",ch,"');
  end;
 WriteLn;
 until ((ch=#27) and (lc=#27));
end.

----------------------------------------------------------

Whatever console I use to -
- putty with windows to the linux server
- ssh from a differant machine to the linux server
- windows NT telnet to the linux server
- KDE's console

The results are that some keys do not return any results.
or like I said the KDE-console and Putty-SSH returns:
  <ESC>,'[','H'  sequenz for the "Home" Key on the keyboard
  <ESC>,'[','F'  sequenz for the "End " Key on the keyboard

Only if I'm on the Servers console (directly on the linux machine)
does the function return the results for the <home> & <end> keys 
just as Borland and DOS would.

Does this mean that the problem is within the termcap intepretation
of the consoles' dialog?  If yes, where is "termcap" explained?


my regards and happy programming,
Stefan

These look like VT100 escape sequences, which would be expected for a termcap'ed interface, rather than a direct keyboard read.

KDE-console also doesn't say anything about the keyboard mapping. The default mapping
(Xfree 3.x xterm) would also not work with midnight commander and other tools. Only the
XFree 4.x xterm mode works correctly.

Has anybody developing the FPC compiler given FreeCLX any thought??

FreeCLX is the GPL'd portion of the CLX that comes with Kylix and will come 
with Delphi 6. 

As Kylix rocks, and is Delphi language compatible, can we assume that FPC will 
compile and run against FreeCLX?? Is anyone thinking/working on this?? I figure 
it should be pretty easy, appart from the slight dialectual differences between 
FPC and Delphi/Kylix.

Take a look at: http://sourceforge.net/projects/freeclx/

Nothing to download yet, but afaik this will be the 'hub' for the FreeCLX.

I don't have the Linux version of FPC downloaded, otherwise I'd try it ;) (not 
enough of a masochist to try porting to windows!!)

The LCL/FCL status seems to be slow,. and FreeCLX is already theoretically a 
fully tested product - release quality.

Just thought that Lazarus could do with a kick up the arse (joke!! no flames 
please!!) Having used Kylix for the last few months (yes beta) I can say it 
currently kick Lazarus/fpc's collective Linux butt :P

We know. Actually, the GPL is a problem, since it explicitly forbids
development of commercial applications. the FPC license does.

Partly, yes. But I wouldn't try to develop serious applications with it yet,
given the long list of bugs and the fact that Kylix crashes still about 20
times a day. But it is definitely easier to make small apps.

Actually, it is NOT so easy, since there are some issues:
- Multithreading support of FPC is not yet finished
- WideString support also is not done
- Variants are not yet integrated in the language.

These are the main issues, and they require some work on the compiler.

You can use CVS to download the FreeCLX. I have a copy. If you look at the
bug list you'll also see a series of bugs I submitted, some of them quite
basic.

There is no need to port this, it will run on Windows as is.
Delphi 6 ships with it. (Should be available June 8)

Actually, there is quite some progress, just the websites are not really
up-to-date.

I beg to differ. I have extensively worked with kylix, and it is _not_
release quality. Late-stage Beta at most, but not release.

What is more, many essential parts (netclx, midas, reporting tools) are
missing from the commercial and free version.

I agree that development is definitely easier with Kylix.

But, may I remind you that
1) Qt (the underlying building blocks of VisualCLX)
   is maintained since about 5-6 years by a commercial company.
2) Kylix is managed by a company with about 800 employees, of which about
   50 on the R&D staff only.
3) FPC is maintained by essentially 6-7 people in their spare time.

Given that, I think the comparision is not really fair.

But, as I said: We're working on it, and in a year or so, we'll see who
will kick who's butt, to use your words :)

That said, feel free to join in, we can use some help.

Michael.

Sorry, not seen that at all. Never had it crash on me since FT 2 or 3. The
release version is stable under Mandrake 7.2.

All this is planned however?

FPC could be used to put FreeCLX onto platforms not yet supported by Borland
(BSD etc.)

Only looked at it really quickly.. nothing in the Files section.

One good reason to update them then ;)

I'm currently using Kylix Desktop Developer - no problems at all. Not had
any problems under Mandrake since FT 3 (the first one that was usable) and
to be honest the release version works like a charm ;) Which distro are you
using? Used Kylix under Mandrake 7.1 and 7.2.. wouldn't touch any other
distro bar maybe Red Hat.. not really into sparse installers... (mind you
Suse is probably better than it was last time I used it by now!)

Not missing much. A whole bunch of SOAP and XML from the press release I
have read.

There are only about 2 guys working on Delphi at any one time. More come
release time, but on average two guys, for the whole product. (or so I was
told by a Borland employee.)

Kylix is a commercial product that cost money to produce.. FPC is free.. It
all kind of evens out in the mix ;)

That's exactly what I want to hear.. though Lasarus was supposed to be

Oh that I had some time!! I'd truely like to get a MacOS/BeOS port under way
(PowerPC for Mac, 8086 for BeOS) but I don't have the time. I have a fairly
basic 6100 powermac now, so if anyone needs a beta tester for the Mac Port..
I'm there dude!! I'm helping out on a few other projects that are PalmOS
based... Hopefull they'll surface soon!!!

That is the problem. If we use FreeCLX, then we would be less free.

If we would build something on it, nobody could do anything commercial with
the result, and we would depend on Borland to decide what was commercial or
not. (And RMS would be on Borlands side on that one).

As a result, we can't build anything of some size  on top of it, so the only
reason for porting would be compiler testing. So the porting should be done
(for testing and for GPL apps), but there is no real hurry, since it isn't
going to be a building block.

GPL is not a problem for end applications, but

This is something I have been wondering about th FPC licence.  I see all of
the various game basics like DarkBasic/BlitzBasic etc. and was considering
doing a Pascal variant.

If I were to make an IDE and code libraries designed for game making, could
I sell a bundle containing these and freepascal?

It would seem just a waste If I had to write a pascal compiler myself
because This isn't the area I want to focus on (I'd rather be working on
tools).

NT (and 2000) have a function specifically for this purpose,
WaitForSingleObject (Sleep is also available but GUI programs should avoid
using Sleep). This function returns if either the object is waits for
becomes signaled or the timeout interval elapses. We can simply use our own
thread as the object to be waited for. It will remain non-signaled while it
runs, thus the timeout will prevail. The thread stays in a very efficient
wait state during the delay, consuming very little processor time. The
actual call would be:

WaitForSingleObject (GetCurrentThread, DelayMS);

Imho John is in search of a cpu-releasing delay routine which works for
GO32V2 programs in a NT VDM.

Yes.
You cannot charge for the FreePascal compiler, but you can charge for your
own program.

And you cannot integrate the compiler or IDE, as that would violate the GPL,
it has to remain a standalone binary.

Yesterday I had - in 1 evening - about 10 crashes, while debugging a _very_
simple program. Mostly errors occur when debugging.

I use SuSE 7.1, and the installer beats anything else I have seen, including
various Windows versions. But that is my personal opinion.

Not missing much ? No reporting, No midware, no apache stuff ? This is
why people would buy Kylix ! You don't need kylix for a small app with 3
edits and a memo, you need kylix for the more serious work.

SOAP and XML are nice in the D6 version, but the Kylix version is far from what
D5 professional/enterprise offers...

This definitely conflicts with what I have _seen_ when I was at Borland.
Maybe he was talking about the compiler and IDE, but the VCL needs lots
of work and I doubt this can be done by 1-2 persons on average.

Did it last night. The bug list isn't too high!!??!! I've seen much worse,

Mandrakes installer beats suse.. at least the last suse I used.

You get the server edition for all that stuff.. To be honest, giving away the 
DB controls with the basic version is 'very unlike Borland'.

I had this discussion the other day with a fellow co-worker. What's the point 
in having slick technologically advanced controls if the compiler sucks?? I'd 
rather get a rock solid compiler and IDE before I get a whole lot of extra 
stuff on top.

As for your crashes.. The Borland released GlibC patches are notoriously bad. 
Did you try the official ones from Suse? A lot of the crashes go onece you do 
so.

But the VCL/CLX is common across the C++ Builder/Delphi/Kylix toolset, so that 
doesn't really count as pure *Delphi* development.

The GPL doesn't forbid the writing of commercial programs, but of closed 
source programs. That's not the same (there are plenty of free closed 
source programs, though the reverse doesn't happen that much).

> If I were to make an IDE and code libraries designed for game making,

You libraries would be no problem, but the IDE is  something else. The 
GPL says that all "derived" works of a GPL'd piece of code have to be 
released under the GPL as well. The problem is that no-one really knows 
what is derived and what not. That's one of the reasons why Apple 
includes no *crucial* GPL'd tools with Mac OS X. Otherwise, RMS could 
decide that because for the OS to be able to function, it requires some 
piece of  GPL'd code, that the whole OS falls under the GPL...

Personally, I wouldn't mind at all if someone would write a closed 
source IDE for FPC (and I don't think anyone else would either, in fact, 
I think there are already some), it's just that GPL is very viral in 
nature and that you have to be careful for open source fanatics in this 
regard...

And as I said, the "derived" part is not strictly defined anywhere, so 
it's very well possible to interpret it so that an IDE which doesn't 
share any code with the compiler isn't a derived work.

I routinely use programs compiled for w32 under Windows 98, NT 4.0,
and Windows 2000 with no trouble whatsoever.

Perhaps this is the problem area you should be addressing, rather than
trying to find a sleep/delay procedure for GO32V2.

I also think this should be addressed then, instead of some ad-hoc patch.
If you can explain (preferably with some example code) the probles you're
having with locked files, maybe we can try to solve them.

The problem is that Windows keeps a lock on a file for a few seconds 
after a (Win32) program has released it, that's all. It's an OS 
bug/feature, I don't think you can work around it in your program 
(except for always trying during 2 seconds or so to open a file before 
giving up, but that's not very nice)

I was intending to address the file issue later when I'd got my dos program
working - which it is now but using a work around & doing an exec of 4nt
sleep-horrible but until I get dos delay working the best I can do. Another
reason for using dos is that a dos program sems to be more efficient using
less cpu overhead...but I'd be happy to use win32 if it'd work!

Anyway talking w2000 here...& I'm opening a file for read every 2 seconds
that is created by the nt/w2000 performance log service...I can open it &
read it ok in fpc go32 ok... but I get an access error in fpc win32
program...but it'd be good to have a proper dos calleable delay that
releases cpu anyway imo, that's why I'm trying to find/make one!

Try opening it with filemode:=$40. Perhaps the win32 problem is with access

filemode:=0 is okay for DOS programs, but not necessarily so for Win32
programs. I had a similar problem before and filemode:=$40 seemed to cure a
lot of the "access denied" errors I was getting with a filefind utility I
wrote. Perhaps that's the only problem with your program as well.

I wish I could be more help about the rest of the filemode settings for
Win32, but unfortunately I don't recall where I got that info from. Sorry.

Could you provide an example program? I tried running several programs on NT
4 now, observing all the handles they keep open (using HandleEx from
SysInternals) and their release was instantaneous as I closed the programs
themselves.

I have written a program some time ago where two EXEs were communicating
through DDE and using a common file for passing data in one direction and
results or error messages in the other. As soon as Program 1 wrote the data
to be processed, closed the file and notified Program 2 to start processing,
the second opened the file and started to work immediately. During the two
seconds you mentioned, hundreds if not thousands of such file close-reopen
operations were made, without any need to wait.

 From the file Win32.inc:

    fmShareCompat    = $00000000;
    fmShareExclusive = $10;
    fmShareDenyWrite = $20;
    fmShareDenyRead  = $30;
    fmShareDenyNone  = $40;

If you check out Syswin32.pp from the RTL source (procedure Do_Open), you'll
see that the single Filemode value passed on by routines like Reset or
Rewrite will not be used directly but dissected into several flags and then
fed to the appropriate Win32 routines. I didn't check if every possible
value and flag is handled by the FPC RTL or not, but you can always call the
Win32 file I/O functions directly, providing whatever flag you want. The
MSDN documentation of CreateFile has a description of all flags accepted by
Win32.

thanks for this info... 

Yup filemode equals $40 fixes my win 2000 access problem to a win2000
performance log...- I was originally advised to use 0 in [devel]! 

IMO one shouldn't need to look at the source...the info below should go into
docn, under reset/rewrite + short explanation of filemode 'To open files
which may be open and used by other processes filemode can be used. THE
DEFAULT SETTING IS ??? It can be set to the following values, dependent on
the operating system...'

Don't think filemode does anything under Dos. Does filemode do anything for
unix/linux/m68k? What values are appropriate? If so can this be explained
too...TIA J

filemode does have an effect for DOS as well, but the number of modes (and
some of the corresponding settings) are different. AAMOF, there are
differences for the ioresult return codes from open(), reset(), rewrite(),
etc.

yes, but what are these constants and what if some constant has no meaning

Why do we need a new way?  The current filemode values all support opening modes
correctly. 

The only missing thing for easier accessing are the fm<Mode> constants in the system unit.
I don't have tp here so i can't check the tp7 rtl for it. For delphi/kylix they are
defined in Sysutils

In BP7, there is this:

{ File mode magic numbers }

  fmClosed = $D7B0;
  fmInput  = $D7B1;
  fmOutput = $D7B2;
  fmInOut  = $D7B3;

This what you are looking for?

The current way is o/s independent! So i don't see why a new way should be created. It'll
make things only more incompatible and complex.

Hello!
A long time ago....
I found error on the GTK unit over FreeBSD.
I thinking much more, and I found the solution.
I rewrite in the source of the FreeBSD/GTK unit gtk/gtk.pp and gdk/gdk.pp:
 gdkdll='gdk' -> gdkdll='gdk12'
and
 gtkdll='gtk' -> gtkdll='gtk12'

Please correct this error on the FreePascal 1.0.4/FreeBSD distribution.
Thanx : Boci
ps: after this little modification the FreePascal work very well :))))

Actually, this is a common thing on FreeBSD platforms... not unique to

 It isn't fully OS independent, in fact, because FileMode constants 
don't have the same meaning on all supported platforms. The trouble 
John is having is probably caused by the fact that DOS with SHARE.EXE 
loaded (which is simulated by all VDMs) uses sharing mode of 0 (i.e. 
none sharing mode specified) as the so-called "compatibility mode" 
with basically the same behaviour as "deny none", whereas you have to 
use a specific (different) sharing mode number on other targets 
(including Win32 and OS/2) for this. We could probably add a 
workaround for this to do_open, the question is, whether we want to 
do so (it would break compatibility with previous releases, among 
other things).

1.0.5 is the development version, the next release will be called 1.0.6. This release will
only contain fixes and no new features. So no thread support. 

Thread support is planned for 1.2, but still needs some decisions how we are going to
implement and distribute it.

A snapshot for 1.0.5 is downloadable from the FTP site. Contrary to the
other platforms, for FreeBSD it is advised to use the snapshot over the
release version.

The pthread unit from the contributed webpage was never tested with FreeBSD,
but when you do it, don't forget to install the LinuxThreads port, since
pthreads probably interfaces to THAT package, not to FreeBSD kernel based
threading.

Moreover I ported the Linux emulator code of the Linux CLONE function to
FPC, and it is supplied as linux.clone (unit linux, function clone). This
because the FCL threading is based on it.
This however hasn't been tested well.

Hmm, odd.

What are you using to run the terminal? 
1. Ncurses (ncrt), 
2. the plain Crt, or (in this case, try (1))
3. no external units?

This is hard to say. Are you using the CRT unit ? if so, then this
is probably the cause; try removing the CRT unit, or use the ncrt unit.

I second this important motion!  My working environment comprises
hundreds of console .EXE files, which suddenly got a lot bigger when
1.0.4 replaced 1.0.2.  I want them to be small again.

The readme is outdated. In previous versions, the executable was named
differently for most platforms, but this was changed in version 1.0.4.
It's now called ppc386(.exe) everwhere.

Message-ID: <200105161403570517.0A62157A@mail.inet75.com>

Hi,
  The current (May/June) issue of the Embedded Linux Journal (http://embedded.linuxjournal.com) is running a contest using the ThinkNIC (http://www.thinknic.com) internet appliance as an embedded system.  I am thinking of entering this contest using FreePascal as the programming language, and would like to know if anyone could make any recommendations or would like to help (I don't think I could share the prizes if we won, though. ;^) )

  I hope this message isn't off topic, but perhaps others in the FreePascal community might want to enter as well, and if one of us made it as a finalist, then it would be great publicity!

  Anyway, here is what I plan to submit as my entry.  If anyone wants to give me some pointers on cleaning it up, I would appreciate it.

Thanks,
  Jeff Wormsley

- - -

Hello,
  I am seriously considering entering the NIC contest, but I am unsure if my limited Linux experience will allow me to complete it.  But, with the availability of resources such as the Embedded Linux Journal and many newsgroups and websites out there, I think I may be able to do it.  So, here's my entry.  We'll see!

1. What is the title for your project?

Linux Digital Jukebox

The concept is to build a replacement for bulky, expensive, hard to maintain jukeboxes (this is NOT yet another home/car MP3 jukebox!) by using commercial, off the shelf products and employing the Linux operating system.


2. What need or desire will your embbeded Linux project satisfy?

Tranditional jukebox systems employ complicated mechanical systems for changing CD's or 45's.  These systems are expensive and very prone to mechanical breakdown.  Loading and unloading these mechanical changer units is also a difficult and error prone procedure.  Also, the control boards in these units are expensive to replace when damaged, and are difficult to update.

By replacing the control system with low cost, commercial off the shelf (COTS) PC components, and the mechanical changer systems with very low cost, easily replacable hard drive units, system costs can be greatly reduced while increasing reliability, capacity, and upgradeability.  The Linux operating system can control most of the needed functionality of a jukebox system "out of the box", and can easily support remote diagnostics, software upgrades, and content replacement via either dialup or broadband (preferable due to file sizes) internet connections.

The resulting system will be much smaller than a conventional jukebox, offer much quicker search times for finding selections (including category, artist, and song title lookups), cost far less than conventional jukeboxes, offer a much larger selection, and be much easier to maintain.

Bullet List
-----------

o Low cost hardware and software
o Ease of updates (via internet)
o Greater capacity (Approximately 300 CD's on a 20GB hard drive, vs typically 100 CD's per jukebox)
o Greater reliability
o Easier use by customer via genre and artist searches
o Smaller size
o Easier accounting

3. What are your qualifications for carrying out an embedded Linux project, including programming and hardware experience?

While my use of Linux has been limited (light hobby use of FreeBSD and RedHat 5.0 through 7.0), I have been a professional programmer for 10 years, working with both PC and embedded systems.  I have developed applications in C for Echelon Neuron processors with as little as 256 bytes of total space (code and data).  I have programmed in Pascal since the earliest Turbo Pascal for CP/M machines, and currently concentrate on coding with Delphi.  This experience can be leveraged into the chosen language for software development, FreePascal, which I have had experience with as well working with the Lazarus Project.  My formal education is a BSEE from the University of Tennessee, and my current job is approximately 25% embedded design related, with the remainder in back end PC systems, supporting the embedded systems, as well as smart card applications.

4. What additional hardware, if any, are you considering using?

For faster boot time, I am considering replacing the 4MB flash card with a 32MB Compact Flash card as detailed in the May/June issue.  The CD-ROM drive will be replaced by a large (20 to 40GB) hard drive used to store song files.  Since the ThinkNIC does not have parallel or serial ports, nor an ISA bus, the keyboard will be modified to control a pulse mode bill validator, using the pulse relay output to drive a keypress, and the SCROLL LOCK LED to control the validator's Bill Enable line, with interfacing circuitry in between to adapt the signal levels and timing appropriately.  To reduce cost, a standard CRT will be used for display, although an LCD panel would be more appropriate to reduce size, heat, and RF noise.

5. What software do you plan to develop?  What tools and or libraries do you plan to use?

The first generation software will provide a simple graphical interface to control the playing of songs, displaying of cover art images, and control the bill validator.  Also included will be simple accounting functions usable by the system operator.  Later versions will incorporate remote software and content updates, both via an external telnet login and via front panel access to a server based repository.  Billing and licencing issues can be incorporated into the server, for example to handle collection and reporting of RIAA public performance fees.

The software development will be done with FreePascal wherever possible, supplemented by C if required.  Libraries will include either the SVGALIB, Graph3d, or fpGFX libraries, and one of the available Linux MP3 (or other compressed digital audio) libraries.

6. What sources of information and support will you consult while carrying out your project?

Linux Embedded Journal - Information on building very small customized kernals (ie: BusyBox project) and using Compact Flash interfaces.

www.freepascal.org - Freepascal documentation and libraries.

Usenet Newsgroups with Linux and embedded system focus.

Linux websites such as the Linux Router Project that concentrate on creating very small but useful kernals.

Various books on Linux usage and development.

Considering the scope of this project, I will most likely consider creating a SourceForge project and invite other members of the FreePascal community to assist in the project, if they would like.

I think it is a very interesting idea; I don't see any obstacles which
would prevent you from making such a system using free pascal. Many things
should be available already, FPC could be used as the glue to make things
work together.

The only tricky thing might be controlling the bill validator.

Michael.

I think that can be done fairly easily.  I plan on stripping a keyboard and tieing the relay of the validator to a key (like F6 or some other rarely used key).  So, each bill pulse will just be a keystroke.  There is an enable signal on the validator, and I plan to use the keyboard's scroll lock signal to control that.  There is a brief moment at power up that it is on, but no one should be using it when it is powering up.  When my program is ready to run, I can turn on the scroll lock (I know how to do it in DOS/Win32, shouldn't be difficult in Linux) and the validator should be enabled.  If the ThinkNIC had a serial port, I would use the more modern MDB (serial) validator, but as it is, that would entail buying a USB serial adapter and figuring out how to get USB support to work on the box, which is beyond my abilities.  (There are only USB drivers for about 5 printers included with the package, and several people have had no luck getting USB to parallel port drivers working with it.)  If worst comes to worst, Hagstrom Controls sells a Keyboard to I/O controller that is programmable.  But I would rather avoid the $120(US) it costs to buy such a thing.

Subject: [fpc-pascal]Free Vision / Turbo Vision.
Message-ID: <20010516211855.C728@thales.canvas.no>

As Free Vision is not released (originally because it was more
or less copied from Borland code), I wonder if the solution Virtual
Pascal has selected could "make things happen" for FPC as well:

Virtual Pascal provides patches of the original TV source to
adapt TV to OS/2 and Win32.  So if I have the BP-TV source (which
I do) I can patch TV for VP's native plattforms...

To the point:  Is this a feasable option for the FPC team, at
least for Linux (hint, hint ;)?  Or will this be so much work
that Free Vision is closer to release than this option?  Or could
the (now withdrawn) FV-version be easily adopted to this scheme?

Sorry to bother you with this, but I'm eager to build Linux-
versions of my TV-apps!  ;-)

This has actually been proposed several times, so an attempt could
be made to do this.

On the other hand, Pierre Muller seems to have the new FV to a point
where it can actually run an application. Since the patch for TV is
almost as big as the sources itself, it may be a better strategy to
cooperate with Pierre to get FVision to work.

That sounds like good news to me!  The release of FV should be "real
soon now" - hopefully(?)!  ;-)

Subject: [fpc-pascal]RE: FreePascal installation for OS2 / accessing PostgreSQL database
Message-ID: <3B0E0364.4FCF3430@bigfoot.de>

Hallo Arne,

thank you for your answer.

Yes I've tested also VPascal.
Usually I use the Sibyl compiler, which is quite similar to Delphi.

My original intention to test VPascal and FreePascal is, that I try to
get a client interface to PostgreSQL working under OS2 using the written
Pascal units. But I've bad luck. Something is (or I'm doing) wrong. EMX,
the Postgres-DLL (PQ.DLL) and my unit (imports PQ.DLL functions) does
not work together somehow.

Also delivered sample units for FreePascal and VPascal I do not get
running. Somewhere a file "c.a" is requested, I do not have. Using the
other compiler (and sample) I get the result "Connection terminated by
SIGSEV" (from EMX).

All I know is, PostgreSql installation is correct, because the delivered
PSQL.EXE does work.

I'm nearly at the end of my ideas.

Any comments are welcome.

Best Regards and Thanks.
-Holger

P.S.: Please answer to schischi at bigfoot.de too, I'm not a member of the
list yet.

Hi all,

we uploaded port of FreePascal for BeOS in it's current state and made it
available to public. We will write some ReadMe file containing information
how to compile it and what is still needed to do...

This port is not finished and we have no more time to work on it, hope
someone can continue...

Hi Michael and list!


I am a teacher in the process of making the computer science department of a brazilian university and a college switch fo free pascal. So far, everybody is liking it!

I have the Windows version of MySQL installed but cannot link the testdb.pp example suplied with fpc-1.0.4 for Windows. I tells it cannot find -lmysqlclient...

My ppc396.cfg is points to the lib directory of my Mysql installation. Using the debuging options from ppc386 and ldw I could find it is looking for libmysqlclient.a and not mysqlclient.lib as suplied with mysql. I tried creating a copy using the name expected by the linker, and now it complains it cannot find -lm. :-(

Should I get a libm.a file somewhere (from a cygwin32 distro)? Or am I going the wrong direction?

Any help will be apreciated. It will be great to fave a FPC app using mysql and gtk+ running on both Windows and Linux. :-)

There is supposed to be a DLL called libmysql.dll that should probably be
copied from the MySQL installation to the Windows System directory.   Oddly
though, not all distribution packages of MySQL for Windows has this DLL
included.  I managed to get the DLL from an older distribution of MySQL and
it seems to work fine with the current version.

I get it working by removing the last lines (complete INPUT) from link.res
and running ppas.bat, but can someone explain it?

this is what I erased from link.res file:

INPUT(
-lmysqlclient
-lm
-lc
-lc
)

With the 1.1 development compiler it is possible to create such import library
automatically on compiletime. This will then require the .dll to be available

Which revision of the mysql.pp do you have? 1.5 is the correct version, it contains the
next lines:

{$ifndef win32}
{$linklib c}
{$linklib m}
{$endif}

this will result in not having the -lc and -lm in the link.res

I downloaded latest snapshot right now and tried to compile my program.
Compilation failed because compiler can't find file "libpwindows.aw" ...
where to get it? or how to generate it?

Yes it's v1.5

and contains

Which revision of the mysql.pp do you have? 1.5 is the correct version, it
contains the 
next lines: 

{$ifndef win32} 
{$linklib c} 
{$linklib m} 
{$endif} 

this will result in not having the -lc and -lm in the link.res

But in that case, the library 'mysqlclient' should not be looked for, so
with which compiler are you working ?

Normally, the windows unit is *always* compiled smartlinkable (because 
otherwise you get problems with functinos which are available only in 
certain windows versions) It should have {$smartlink on} at the top 
somewhere in it.

Use -va while compiling the unit to see what is rejected and accepted 
regarding defines. The most likely is that the compiler is using another 
compiled unit somewhere, use -vt while compiling your program to see 
which one.

Don't do that. You can use them alongside eachother, but don't mix untis 
from one with another, it won't work most of the time.

Hello,

I search a source code for a TCP/IP packet sniffer written in Pascal for
Windows (or in the worst case scenario Linux). I need this tool to try do
decode communication protocol between 2 programs to insert and modify data
from a 3rd program (like a aiming proxy for quake :-( ) but for a real world
industrial application :-).

That should work, as both 1.0.x and 1.1 branches use exactly the same sources.

My installation of MySQL includes libmysql.dll, but it is not enough. MySQL docs tell you must link against libmysql.lib to use libmysql.dll, so I tried this, renaming libmysql.lib to libmysqlclient.a as fpc looks for. The result is the same as before, ldw complains about missing -lm.

Maybe you have a complete cygwin32 environment installed or some other package that provides libm.a just like an Unix OS would.

My debugging shows that the compiler (actually ldw.exe, the linker) is looking for libmysqlclient.a. Renaming the libmysql.dll or libmysqlclient.lib to libmysqlclient.a solvers the error about -lmysqlclient but shows a new error about -lm.

The MySQL manual states you need to link libmysql.lib to use libmysql.dll. I guess I need to get a working libm.a from somewhere, maybe cygwin.

Really works, that is, the program can connect to a mysql database and get data from it?

I guess libmysql that contains the references to libc and libm as needed to generate an executable. Does anyone knows how check this, and if I am right how to patch the (mysql) libraries so they do not include this information anymore?

By the way, the same error (about -lm and -lc) happens when I try to compile the Interbase 6.0 demo. The Interbase 4.0 compiles, links and runs fine though.
