Hi bkqdad, If the library is a C library (which uses the C ABI), you should be okay. If the library is a C++ library (which uses a C++ ABI), you need to get GCC 4.1.1 of the C++ (g++) compiler for your project, or have the provider of the library compile their library using GCC 3.2.3 of the C++ (g++) compiler.
