Unfortunately I'm running into a problem with check-all, where it fails to link XRayTest-x8664-Test: [100%] Generating XRayTest-x8664-Test /home/dim/llvm/8.0.0/rc1/Phase3/Release/llvmCore-8.0.0-rc1.obj/./lib/libLLVMSupport.a(Signals.cpp.o): In function llvm::sys::PrintStackTrace(llvm::rawostream&)':_ _Signals.cpp:(.text.ZN4llvm3sys15PrintStackTraceERNS11rawostreamE+0x24): undefined reference to backtrace' Signals.cpp:(.text.ZN4llvm3sys15PrintStackTraceERNS11rawostreamE+0x254): undefined reference to `llvm::itaniumDemangle(char const*, char*, unsigned long*, int*)' clang-8: error: linker command failed with exit code 1 (use -v to see invocation) gmake[3]: *** [projects/compiler-rt/lib/xray/tests/unit/CMakeFiles/TXRayTest-x8664-Test.dir/build.make:73: projects/compiler-rt/lib/xray/tests/unit/XRayTest-x8664-Test] Error 1 gmake[3]: Target 'projects/compiler-rt/lib/xray/tests/unit/CMakeFiles/TXRayTest-x8664-Test.dir/build' not remade because of errors. gmake[2]: *** [CMakeFiles/Makefile2:33513: projects/compiler-rt/lib/xray/tests/unit/CMakeFiles/TXRayTest-x8664-Test.dir/all] Error 2 gmake[2]: Target 'CMakeFiles/check-all.dir/all' not remade because of errors. gmake[1]: *** [CMakeFiles/Makefile2:737: CMakeFiles/check-all.dir/rule] Error 2 gmake[1]: Target 'check-all' not remade because of errors. gmake: *** [Makefile:277: check-all] Error 2 [Release Phase3] check-all failed It appears this is because -lexecinfo is not passed to the link command line, but I'm unsure why this only seems to affect the XRay test. I'm investigating, but if anybody has a cluestick, please hit me. :-)

We've been having similar issue on NetBSD in the past. Long story short, the code around there is not using CMake rules to build stuff but a custom compiler invocation, and therefore it does not inherit library dependencies from CMake.

Short-term solution is to figure out what's missing and add it, with appropriate conditionals.

Long-term solution (which is probably not suitable for 8.0.0) is to rewrite that whole stuff. Probably could work by creating a custom language for CMake that's like C but uses just-built clang, etc. However, that's just my theory and I'm not 100% sure it'll work or how much work it'd involve.
