Is it possible to use libraries build under VC++ in cygwin gcc build?

I have libraries which are build using VC++. I want to use the开发者_运维百科 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 __stdcall instead 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.

Probably not

There is mingw a port of GCC (and lots of gnu tools) to windows which uses standard windows libs - it's pretty much a drop in replacement for cygwin and should be easier to link to gcc.
