My program compiles as 1 file, but not when broken up into multiple files. It complains about "undefined references" to the functions in my other files. there are .h files with function prototypes that are very clearly listed with #include "file.h" at the top of my .c file. All the files are in the same directory. I'm using gcc on linux.
