There are a couple software engineers in our company that are now running Windows 7 64bit and can no longer run MS Visual Studio 6.0 (compatibility issues). I am not a software engineer, but they have asked me to find a free C compiler and IDE based Source-Level debugger package that can run on Windows 7 64bit. I really have no idea what that is and am hoping someone here can recommend something? I saw a package called Eclipse, but it is simply called IDE for C/C++ Developers...not sure if it is a compiler or source-level debugger. Any suggestions?
