[Gm2] gm2

[Charles Bradshaw]

Following my partial success with gm2 I tried to compile
testexecutive.mod

Now depending which version 4.7.3 or 4.1.2 I use I get various failed to
find errors. Either the previously reported -fmakeall bug or with 4.1.2:

address@hidden executive]$ gm2 -g -c testexecutive.mod
failed to find definition module Executive.def

The output from this makes my brain hurt:
address@hidden executive]$ gm2 -print-search-dirs

So I append \n after the :

install: /home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.1.2/

Non of which is useful because the missing def is else where:

address@hidden executive]$ locate Executive.def
/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.1.2/gm2/pim-coroutine/Executive.def

So using the -I option:
address@hidden executive]$ gm2 -g -c
-I /home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.1.2/gm2/pim-coroutine
testexecutive.mod
failed to find definition module SYSTEM.def

But SYSTEM.def is in the included path!

address@hidden executive]$
ls /home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.1.2/gm2/pim-coroutine/SYSTEM.def
/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.1.2/gm2/pim-coroutine/SYSTEM.def


If I do, as is suggested in the README:
address@hidden executive]$ make
I see:
failed to find definition module

This is all very confusing!

Can I set some environment variables to fix these problems?

May I respectfully suggest that compiling default search paths into gm2,
or wherever they go, is a bad idea.

Good old Topspeed Modula 2 used a configuration file called M2.RED which
lived in the current directory, thus:

When working in the directory c:\ihi\control

C:\ihi\control\>type M2.RED
*.mod = .;c:\m2\source
*.def = c:\ihi\control\def;c:\m2\lib
*.obj = c:\ihi\control\obj;c:\m2\lib
*.dat = c:\sigma
*.exe = c:\ihi\control;c:\m2
*.map = c:\ihi\control
*.dbd = c:\ihi\control
*.db$ = c:\ihi\control

The contents says it all.
