[fpc-devel] DOS Platforms

I've never been able to make go32v2 make work properly under w2k/xp, and neither has anyone else afaik - because of the well known bugs...Not worth trying imho - best to use real dos.
Current make cycle (just compiler & rtl) & go32v2zip (whole release) works fine under win9x - I use ME.
Both v20x and v21x and v20 release makes work at present for me, using the fpc.zip from ftp & unzipping into clear directories, using the make that's included, dos window under win me. The resulting compiler/rtl sort of works too...As you've heard exceptions cause a crash- they used to work but stopped around Feb 2005, probably when the asm calling conventions were changed for v19.
... I'd try v21x - v20x & v20 will probably then work anyway.
I'll upload v20x & v21x snapshots onto ftp.freepascal.org ... \snapshot\v21 & v20 soon.

Ok, first status on the matter:
Tonight I've spent some time with the sources and my Win2K machine. For
me it seems as the Makefile(.fpc)'s are not yet up to date for the
go32v2 target (object files didn't get deleted on cleanall, some unit
paths were missing, that sort of stuff) [FYI: I checked out the current
2.0.1 from CVS], but in the end I managed to make the compiler cycle
manually. Hmm, well, let's see if I still remember how I did it, when I
get back to it this evening ;).
Result: I get occasional seg faults (probably related to the ntvdm bug
mentioned in the current djgpp, so this is definitely something to
try). I can compile a simple hello world (huhu, what an achievement,
but, hey, look at that matter when it's 3.30am).
Next test was to check some files from the tests/test stuff and those
(very) few I checked seemed to compile quite ok. BTW, the tstring1.pp
failed horribly (on successfull execution of the test, not on
compilation) just like the current fpc does (don't you happen to
actually run these tests?).
So it's definitely some more work to do, especially for building release
version etc.pp., but at the first glance it doesn't look too hard.

Well, if you could manage to send me a makefile, so that I don't have to
hack it myself (using Pascal and Ada for years, I somehow got used to
the fact that makefiles are mostly unnecessary complex and outdated
C-related stuff), that would be nice.
It also seems, I'll get an old Win95 system up und running in the next
few days, so I even can do tests for the most important environments.

Well, I just tested in on my linux box, there it runs just fine (well,
with fpc2.0.0, that is). It *should* not make any difference if I use
fpc1.0.10, should it? Or am I missing something here?

Yes. Even I could understand it. ;-)

Well, at the moment I'd say, I take look at the makefile, see what I do
with those "error setting exception" messages and trying to compile
something larger to test with. I expect hard-to-find effects soon
Oh, yes. One question: Should I use the current fpc2.0.1 release from
the CVS or would it be better to switch to the 2.1.x branch already to
not get too far behind the current development? Just don't say
