In my previous post about FreeDOS tools I mentioned that I hadn’t yet tried to get Gambit Scheme to compile .scm code to a stand-alone .exe. There are a couple of things you need to do.

1. If you’ve not installed to C:\GAMBC, set the environment variable %GAMBCDIR ro point to where you installed it. This allows gsc to find _gambc.c which it needs to compile scheme to c.

2. Make sure you have the DJGPP C/C++ compilers installed.

3. For some “program.scm”:

• gsc -c program.scm - this will create program_.c and program.c
• gcc -L%GAMBCDIR -I%GAMBCDIR program_.c program.c -o program.exe -lgambc

Simple!
