I have libraries which are build using VC++. I want to use the same libraries in a program and build in cygwin gcc compiler. Is this scenario will work?

Since C++ doesn’t have a standardized ABI, and since Visual C++ and g++ in particular almost certainly have different ABIs, I don’t think you can do this. Your only real option is to restrict yourself to C, not C++.
Edit: If all of the libraries that you’re using are straight C (
extern "C", in C++ terms), then you ought to be able to share libraries between compilers. (Otherwise, your Cygwin and MinGW apps couldn’t call the Windows API.) You’ll need to be careful to match up calling conventions. For example, the Windows API uses__stdcallinstead of the standard C calling convention. You can tell GCC which calling convention to use with function attributes. Google, and your library’s header files, should have more information on what calling convention to use.
