[Gm2] Compiling with pim-coroutine

[Johannes von Rotz]

Hello,

I'm trying to port a 30-or-so-year old application over to GNU Modula-2.
Historically it was translated to C using Glance's M2CC and then built
on the target platform using the appropriate C compiler. Since the
number of supported platforms has shrunk dramatically (Basically it's
all Linux on x86 now), this seems to be no longer necessary and so I've
been slimming down the build process. Now I'd like to slim it down even
more, trying to get rid of the translation to C.

The problem I'm running into is the compilation of a module that imports
the NEWPROCESS routine from SYSTEM. As it is my understanding, GNU
Modula-2 provides exactly that with the pim-coroutine library. However,
when trying to compile with -flibs=pim-coroutine this happens:

        $ /opt/gcc-4.1.2+gm2-1.0.4/bin/gm2 -flibs=pim-coroutine \
                -c sys.mod
        failed to find definition module M2RTS.def

So I was thinking: Maybe the pim-coroutine extends the basic pim library
and I have to include it too. But then:

        $ /opt/gcc-4.1.2+gm2-1.0.4/bin/gm2 -flibs=pim-coroutine,pim \
                -c sys.mod
        /opt/gcc-4.1.2+gm2-1.0.4/lib/gcc/x86_64-unknown-linux-gnu/4.1.2
        /gm2/pim-coroutine/SYSTEM.def:19:1: error: unknown symbol
        'CARDINAL32' found
        /opt/gcc-4.1.2+gm2-1.0.4/lib/gcc/x86_64-unknown-linux-gnu/4.1.2
        /gm2/pim-coroutine/SYSTEM.def:19:1: error: unknown symbol
        'INTEGER16' found
        /opt/gcc-4.1.2+gm2-1.0.4/lib/gcc/x86_64-unknown-linux-gnu/4.1.2
        /gm2/pim-coroutine/SYSTEM.def:19:1: error: unknown symbol
        'INTEGER32' found
        /opt/gcc-4.1.2+gm2-1.0.4/lib/gcc/x86_64-unknown-linux-gnu/4.1.2
        /gm2/pim-coroutine/SYSTEM.def:19:1: error: unknown symbol
        'CARDINAL16' found
        /opt/gcc-4.1.2+gm2-1.0.4/lib/gcc/x86_64-unknown-linux-gnu/4.1.2
        /gm2/pim-coroutine/SYSTEM.def:118:5: error: the following
        symbols are unknown at the end of module 'SYS' when requested
        by another modules import (symbols have not been exported by
        the appropriate definition module)

Can someone shed some light onto this? I'm puzzled.

Cheers,
Johannes
