Like you, I recently took first steps with gm2 (not first with modula-2) and 
like you, I assumed that gm2 foo.mod would work.

However, at this stage, the gcc environment does not 'know' about the modula-2 
language in the same way that it knows about C, C++, F77, Ada etc.

So

gm2 -c -g -I. foo.mod

tells it to compile

Yes. 

Actually I don't really understand what the -g -I. does, I just copied them from
http://www.nongnu.org/gm2/gm2.html#SEC6

gm2 -g -I. FirstEx.mod

will link and produce a.out which is executable. Use -o to get a different 
executable filename.
