[llvm-dev] EngineBuilder().create() => NULL
Hi, I try to create an execution engine, but I always got a nullptr value : _executionEngine = EngineBuilder(std::move(_module)).create(); I build my project with cmake and add the following command in my cmake. llvm_map_components_to_libnames(llvm_libs Analysis Core ExecutionEngine InstCombine Object RuntimeDyld ScalarOpts Support native mcjit) BTW, I have also try to execute the LLVM example project "HowToUseJIT", and it also return NULL ! And then crash !

[llvm-dev] EngineBuilder().create() => NULL
Thanks, I found that I have to add : "mc mcdisassembler" too, into the list of libraries ! Then it works.
