Because of the way the compiler is tested and used for setting things up, it is not a good idea to change it after the language has been enabled. The way to do what you want is this: export CXX = "distcc mpicxx" cmake ../project You can tell cmake what compiler to use before running cmake with the environment variables CC and CXX. However, I seem to remember a bug with this, and you may have to use CVS cmake for this to work correctly. -Bill _______________________________________________ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
