[Sorry about the crosspost. Since this is a clang build question but the build is invoked from the top-level LLVM directory I'm not sure where the question should go.] I've got a clang build against libstdc++ on Linux but I would really like one built against libc++/libc++abi. In other words I'd like to rebuild clang/llvm with clang using libc++ and libc++abi on Linux. I looked at

Just to follow-up, I'm now encountering this as well. I'm doing this on Linux. It seems that when linking with the most-recently built clang, the unit tests are taking a while to complete. It's notably not using more than 1 thread, and if using `lld` I would have expected the linker to still be running in parallel. I'm doing this on a debug build, so that might help narrow it

Try as I might I can't seem to get LLVM to bulid using clang/clang++. No matter what I do it insists on using /usr/bin/cc and /usr/bin/c++ which are gcc. Am I missing something obvious? I vaguely remember some document describing a stage1 compiler built by your old toolchain and a stage2 compiler but I can't find the steps to do that any more. $ CC=/usr/local/bin/clang
