main() is where your program begins, if that's missing it can't create an executable. Libraries on the other hand don't need a main().
Check that the code which is supposed to define it is getting compiled, and also check that main is being exported properly. If it's being hashed into a C++ overloaded name, the linker might not find it. You could give it a definition to avoid it being name-mangled.
