My primary interest I guess is a replacement for Kylix under Linux but
I would also like to be able to use Lazarus under OS/2 and OpenVMS, so
first of all I want to find out how far the project has come on these
three platforms. Especially important is whether Lazarus can compile
an existing program which I now maintain using Delphi 2005 on MSW and
Kylix on Linux. It currently uses Indy9 for networking in a large LAN
with Solaris and OpenVMS end users.
This is a mature program, started 13 years ago in Turbo Pascal,
in daily use by others and continually evolving to meet new
I realize that OS/2 and OpenVMS are fringe operating systems so I
expect to have to do some development of both fpc & Lazarus there
myself, the question is really how much work i.e. time is required.
To help me, I would like to know for instance how to bootstrap fpc
on a new platform. What is the original compiler? Any form of
Pascal compiler, gcc or whatever.
How dependent on fpc is Lazarus?

Gtk 1.2.10 is available on OpenVMS and a Gtk 2 has been spoken
about - one day perhaps. Same applies to OS/2. Is Gtk2 essential?

Yes I just downloaded fpcbuild-2.0.4-rc3.tar.gz, extracted the tar
using untgz, ( untgz failed to completely unpack it ) untarred it
with gnu tar and ran 'make os2' using the fpc from os2200.zip which
was the latest I could find.
After that it installed with 'make install'. The only error I
saw was the one about gdb.

That sounds about right.
Re above and compilers, I did notice the EMX libs there, what are
they used for as etc., or is gcc involved somewhere. If it is have
you had a look at the Innotek builds, currently gcc-3.3.5 csd1.
I haven't used gdb much but I understand that the newer gccs from
Innotek are not compatible with the gdb we currently have.
This is of course a concern since the debugger is one of the main
strengths of a good IDE.
