...ons from http://llvm.1065342.n5.nabble.com/llvm-dev-Compiling-for-baremetal-ARMv4-on-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-...

...ure why --gcc-toolchain isn't used, anyway libc.a and libm.a are under $SYSROOT/libc/usr/lib (and I did try --sysroot=...../libc --sysroot=.../libc/usr and --sysroot=../libc/usr/lib, none of which worked) Any idea?

...gling things led me to this thread. http://llvm.1065342.n5.nabble.com/llvm-dev-Compiling-for-baremetal-ARMv4-on-Ubuntu-Linux-td124226.html After going through this 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...

So I have copied BaremetalARM.cmake into llvm/cmake/caches/BaremetalARM.cmake to be able to alter it, I've put all other repos in llvm/projects and the command is: # cmake -G 'Unix Makefiles' -DBAREMETAL_ARMV7EM_SYSROOT=~/arm-sysroot -DBAREMETAL_ARMV6M_SYSROOT=~/arm-sysroot -DBAREMETAL_ARMV7M_SYSROOT=~/arm-sysroot -C ../../code/llvm/cmake/caches/BaremetalARM.cmake ../../code/llvm Before adding all repos into llvm/projects, it complained about 'Specified distribution component 'clang' doesn't have a target' (just an example). Now I ha...
