gcc compiled code on visual studio

Assume I have source code for a lib/tool that works on gcc compiler. Can I use the same 开发者_开发知识库code and compile it in visual studio. will that be possible at all? If it is possible, how do I do it?

if you are just using all the standard C/C++ library like stdio.h, stdlib.h, etc. it should work fine. Pure console program should work fine. If you used some GUI related library (especially if you are porting over from unix to window) then it might not work.

To do so, you can simply just create a new project in visual studio and add the existing source code into the project workspace. Compile it, if you encounter any error, just post here or try solve if you know how

It depends on your code, GCC support a variant of C (C99) which Visual Studio doesn't support yet.
If your trying to compile a Unix program on Windows you best bet will be to use Cygwin.
Check this question for pointers on using Cygwin in Visual Studio.
