More info:

I added a -B path to my gm2 .... hello.mod command, as follows, then I
get a different error:

$ gm2 -g -I. -B /home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3/gm2
-fmakeall hello.mod

gm2 -c -fmakeall0 -B -g -fonlylink -fobject-path=.
-ftarget-ar=/usr/bin/ar -ftarget-ranlib=/usr/bin/ranlib -fmakeall -I.
-I/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3/gm2/pim hello.mod
gm2cc: error trying to exec 'cc1plus': execvp: No such file or directory

A search for execvp produces:

$ locate execvp
/home/brad/GM2/scratch-area/build-4.7.3/i686-pc-linux-gnu/libgcc/_gcov_execvp.dep
/home/brad/GM2/scratch-area/build-4.7.3/i686-pc-linux-gnu/libgcc/_gcov_execvp.o
/usr/lib/perl5/auto/POSIX/execvp.al

I'm clutching at straws with:

$ gm2 -print-search-dirs
install: /home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3/
programs:
=/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3/i686-pc-linux-gnu/4.7.3/:/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3/:/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3/:/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3/:/home/brad/opt/lib/gcc/i686-pc-linux-gnu/:/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3/:/home/brad/opt/lib/gcc/i686-pc-linux-gnu/:/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3/../../../../i686-pc-linux-gnu/bin/i686-pc-linux-gnu/4.7.3/:/home/brad/opt/lib/gcc/i686-pc-linux-gnu/4.7.3/../../../../i686-pc-linux-gnu/bin/

Which produces some very funny looking output, several paths repeated!


Are these deep bugs or am I doing something wrong?
