Any ideas on how to proceed?
Hello again, This is probably because you didn't load the module or unit that defines format (this is the "extras" module). The interpreter has a few units available implicitly by default which aren't loaded into compiled code. This is a bit of a gotcha, which is why we're working on making this more consistent in CHICKEN 5. Anyway, if you put your code in a module the compiler would give an error about a missing import. The fix is to put this at the top of your file: (use extras) This isn't a cross-compilation issue by the way, this would also give an error if you compile and run on the host platform. Hope this helps! Peter
