You can use gcc to compile in GNU/Linux.
However the lcc compiler included there which compiles the qvms is not free software (not GPL'ed, BSD Licensed, or whatever. And you can assume it's not "open source" either). The license puts limits on commercial redistribution.
edit:
I've uploaded the code to
