...-Ubuntu-Linux-tp124226p124500.html, I can only build "libclang_rt.builtins-x86_64.a" in lib/linux, but what I want to build is "libclang_rt.builtins.arm.a". My CMake options are: cmake -G Ninja DBAREMETAL_ARMV6M_SYSROOT=${ARMEABI5GCC} -DBAREMETAL_ARMV7M_SYSROOT=${ARMEABI5GCC} -DBAREMETAL_ARMV7EM_SYSROOT=${ARMEABI5GCC} -DCMAKE_BUILD_TYPE=Release -C/home/llvm-project/clang/cmake/caches/BaremetalARM.cmake /home/llvm-project/llvm/runtimes/compiler-rt with echo $ARMEABI5GCC /home/gcc-arm-none-eabi-5_4-2016q3/arm-none-eabi Does anyone know how to fix this problem?

...s I figured my best bet would be using GCC sysroot. After which my cmake command looks like this. cmake -G "Unix Makefiles" -DBAREMETAL_ARMV6M_SYSROOT=../../gcc-arm-none-eabi-9-2019-q4-major/arm-none-eabi/ -DBAREMETAL_ARMV7M_SYSROOT=../../gcc-arm-none-eabi-9-2019-q4-major/arm-none-eabi/ -DBAREMETAL_ARMV7EM_SYSROOT=../../gcc-arm-none-eabi-9-2019-q4-major/arm-none-eabi/ -DCMAKE_BUILD_TYPE=Release -C ../clang/cmake/caches/BaremetalARM.cmake ../llvm But with this, I am getting this error attached to the email. Is there something I am missing here? Is there any update to the cross-compilation guide? My end goal...

I found https://www.llvm.org/docs/HowToCrossCompileLLVM.html. Is it enough for --sysroot? In case it is,

Hello Peter and Lists, thanks a lot, that way it worked out!
