My regex could probably use some fine tuning, but so far it seems to work well enough: Thanks for contributing an answer to Unix & Linux Stack Exchange! objdump, addr2line, readelf and nm are your friend. My question is that if it does make any sense to specify CMAKE_BUILD_TYPE when libharu's CMakeLists.txt doesn't mention it? does not match the _EXTENSIONS target property, I then try to run the debugger: > lldb hello (lldb) target create "hello" Current executable set to 'hello' (x86_64).
