Hello, I am working on SWIG which converts the functions written in C and C++ into their python equivalent which would be later used in Chimera. At one point while building binaries, I received an error message saying *extensions must be built with a compiler than can generate compatible binaries. Visual Studio 2003 was not found on this system.* So I believe installing Visual Studio 2003 must help building binaries. But since I will be actually working on Chimera Python, I wanted to know which compiler can generate compatible binaries in Chimera Python? Shall I go ahead with Visual Studio 2003? or any other version? Thank you in advance. -- Raju R.N. Third Year, B.Tech Mechanical Engineering National Institute of Technology Karnataka, Surathkal
