Re: [Gm2] Possible bug when using -fmakeall / ncurses example

[Christoph Schlegel]

To be more precise, the module

MODULE test;
BEGIN
END test.

does not compile when gm2 is called with -fmakeall. 'gm2 -fmakeall test.mod' 
results in

$ gm2 -fmakeall test.mod
/home/Christoph/opt/lib/gcc//i686-pc-cygwin/4.7.3gm2 -c -fmakeall0 
-B/home/Christoph/opt/lib/gcc//i686-pc-cygwin/4.7.3 -fonlylink 
-ftarget-ar=/usr/bin/ar -ftarget-ranlib=/usr/bin/ranlib 
-fobject-path=/home/Christoph/opt/lib/gcc/i686-pc-cygwin/4.7.3/gm2/pim 
-fmakeall -I/home/Christoph/opt/lib/gcc/i686-pc-cygwin/4.7.3/m2/pim test.mod
make: /home/Christoph/opt/lib/gcc//i686-pc-cygwin/4.7.3gm2: command not found
/tmp/ccFX0XeM.m:11: recipe for target 'test.o' failed
make: *** [test.o] Error 127

I picked up the temporary makefile in /tmp and found it to look like this:

OPTIONS=  \
        -fmakeall0 -B/home/Christoph/opt/lib/gcc//i686-pc-cygwin/4.7.3 
-fonlylink -ftarget-ar=/usr/bin/ar -ftarget-ranlib=/usr/bin/ranlib 
-fobject-path=/home/Christoph/opt/lib/gcc/i686-pc-cygwin/4.7.3/gm2/pim 
-fmakeall -I/home/Christoph/opt/lib/gcc/i686-pc-cygwin/4.7.3/m2/pim
M2C= /home/Christoph/opt/lib/gcc//i686-pc-cygwin/4.7.3gm2 \
         -c $(OPTIONS)
M2L= /home/Christoph/opt/lib/gcc//i686-pc-cygwin/4.7.3gm2 \
         -fonlylink -I. $(OPTIONS) 

test: test.o

test.o: test.mod
        $(M2C) test.mod

clean: force
        $(RM)  test.o

force:

I don't understand the lines M2C and M2L. Should there be a gm2.exe in 
/home/Christoph/opt/lib/gcc//i686-pc-cygwin/4.7.3 (there isn't)?

Regards,
Christoph
