Folks,
I'm trying to set up a libc++ buildbot on ARM and I found an inconsistency which I'm not sure how to fix. I got a build error like this: libc++abi.so: undefined reference to `UnwindGetGR' Since I expected that the symbol would be provided by that library, I searched the CMake on libc++abi and found this: option(LIBCXXABIUSELLVMUNWINDER "Build and use the LLVM unwinder." OFF) ... if (LIBCXXABIUSELLVMUNWINDER) addsubdirectory(src/Unwind) endif() But on the Libc++AndAbiBuilder, there's no way to set the CMake argument (or is there?): I think you can add "-DLIBCXXABI_USE_LLVM_UNWINDER" to the env argument and get what you want, but Dan will have to correct me on that... def getLibcxxAndAbiBuilder(f=None, env={}, additionalfeatures=set()): "additionalfeatures" seem to imply only lit test args, not anything else. They are lit test args, and triggers for -D defines for various weird configurations (e.g. single threaded). I don't think there is one for the unwinder (nor do I think it makes sense to add one for that).
Cheers,
