I've just discovered the existence of llvm (http://llvm.org/) with your message. I think you may have 2 options: 1) first consider llvm-gcc as a C compiler variant I think you may just set CC env var before running CMake as specified here: http://www.cmake.org/Wiki/CMake_Useful_Variables#Compilers_and_Tools Then, you may need to change some vars in you CMakeLists.txt like CMAKE_C_OUTPUT_EXTENSION or CMAKE_C_FLAGS or see http://www.cmake.org/Wiki/CMake_Useful_Variables SET(CMAKE_C_OUTPUT_EXTENSION ".bc") in order to overide the .o default. SET(CMAKE_C_FLAGS "-emit-llvm) in order to globally add the flasg if it is necessary 2) Consider llvm-gcc as a "cross-compiler" since the target is llvm and not the "native object" , if I understood it well. Then you should try CVS version of CMake which adds support for cross-compilation: http://www.cmake.org/Wiki/CMake_Cross_Compiling -- Erk _______________________________________________ CMake mailing list [email protected] http://www.cmake.org/mailman/listinfo/cmake
