Hello, I have a working GCC toolchain and wanted to use LLVM tooling instead. Following the instructions on the website I set up my build directory and have lld as an internal project under tools/. I'd like to make use of lld in stage 2 of the build and thought -DLLVM_ENABLE_LLD was the correct option to pass. However, adding this options makes the configure step fail, complaining that the

I described this off-list to Zac, but for anyone else who is following, simply specifying the target triple is not enough to have the build system set an older macOS deployment target. I.e the 6.0.0-rc1 binaries I've just uploaded have the same deployment target problem. Looking at the 5.0.0 and 6.0.0-rc1 binaries, I can confirm that their deployment target was too new: Load command 9

I can replicate the problem on Linux with mkdir foo && cd foo cmake -DLLVM_TARGETS_TO_BUILD=X86 ../llvm I'll investigate a bit.

...me that the variable for specifying the toolchain file was unused when I set it on the command line, and none of the variables were propagated. It's been about a month since I tried though, so it may have been fixed. I get that warning, but it works anyway. Some of the options are forwarded (CMAKE_CXX_COMPILER being particularly important) others just disappear (presumably having done their job). >> Do you also see the "make -j9 dies" issue? > > I use ninja -j64 and it works fine.
