Hi, I tried to compile a custom llvm's pass with the usage of a cmake. It does not work. I receive a well known assert in a Pass.cpp: "Pass registered multiple times!". The custom pass has to be linked with the core, support and system archive libraries. This seems to be a problem. I suppose the conflict occurs because opt and pass are using the same libraries. Does anyone have a working cmake for a custom pass? If not then can anyone explain how do Makefiles link libraries to custom passes? The pass is written well because it works with a autoconf's generated Makefile. Best, Mariusz
