My flight simulation club is working on the development on an opensource flight simulator (Fly! Legacy) under GPL license. http://sourceforge.net/projects/flylegacy/ Currently, only a Windows version of this software is available and so, one or several people would be necessary to help us to convert this Windows application to a Mac application. The application was developed in C++ and was compiled with Visual Studio 2008. About the librairies included in the project, I don't know all because I'm not developer of the project but I can tell you that uses: _ OpenGL _ OpenAL _ FreeImage _ OPAL-ODE _ Glew _ PThread _ STLport (not sure) Could you help us ? Thank you for your cooperation.
