Unless you have a specific reason, it is advisable to use the 8.2 graft of gm2 (see the next section).
On a GNU/Linux system you should also be able to build it using these commands. If you are building on a system which supports multiarch then you should type:
$ CFLAGS=-B/usr/lib/x86_64-linux-gnu $ export CFLAGS $ LIBRARY_PATH=/usr/lib/x86_64-linux-gnu $ export LIBRARY_PATH
The above is necessary on a Debian Wheezy x86_64 system, but not on Debian Squeeze.
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-git-latest/gm2/gcc-versionno/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.
