Hi guys,
Im not a C expert or anything and I need help with this issue. I have a long code (10 files or so), that I didn't write. It has a makefile, and all I have to do is type "make" in unix and it complies without errors or warnings, and it work.

I've been trying to compile this in windows, using visual studio, but it gives me A LOT of errors. What I do basically is go to the file that contains main, and try to compile it. I can't seem to find what the reason is. I feel like its having a hard time linking the files together. Any ideas or suggestions. I would really appreciate it.
