On a GNU/Linux system you should also be able to build it using these commands. The following commands assume your shell is /bin/bash. To build GNU Modula-2 type:
$ mkdir -p $HOME/opt
$ mkdir -p build-4.1.2
$ cd build-4.1.2
$ ../gcc-4.1.2+gm2-cvs-latest/configure --enable-languages=c,c++,gm2 \
--disable-multilib --enable-checking=all --prefix=$HOME/opt
$ make "SHELL=/bin/bash"
To install GNU Modula-2, after a successful build, type:
$ make "SHELL=/bin/bash" install $ cd ..
Now you should be able to perform:
$ export PATH=$HOME/opt/bin:$PATH $ cd build-4.1.2/gcc/gm2/examples/hello $ make post-install
which will create an a.out for the infamous hello world example.
