Hi Vitaly, This is the CMake command line I used: cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=$HOME/stage2 \ -DCMAKE_C_COMPILER=$HOME/stage1/bin/clang \ -DCMAKE_CXX_COMPILER=$HOME/stage1/bin/clang++ \ -DCOMPILER_RT_BUILD_BUILTINS=off -DCOMPILER_RT_BUILD_PROFILE=on \ -DCOMPILER_RT_BUILD_SANITIZERS=on -DCOMPILER_RT_BUILD_XRAY=off \ -DLLVM_ENABLE_PROJECTS="clang;compiler-rt;lld;openmp" \ -DLLVM_ENABLE_ASSERTIONS=on -DLLVM_OPTIMIZED_TABLEGEN=on \ -DLLVM_STATIC_LINK_CXX_STDLIB=on -DLLVM_TARGETS...

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

...local/myclang/lib, /lib, /usr/lib, /usr/arm-linux-gnueabihf/lib, so no surprised there. Then I added the suggested -DCMAKE_ASM_FLAGS to the cmake for the standalone compiler-rt build while leaving out the --sysroot and --gcc-toolchain: cmake -G "Ninja" ../llvm/projects/compiler-rt/ -DCOMPILER_RT_BUILD_BUILTINS=ON -DCOMPILER_RT_BUILD_SANITIZERS=OFF -DCOMPILER_RT_BUILD_XRAY=OFF -DCOMPILER_RT_BUILD_LIBFUZZER=OFF -DCOMPILER_RT_BUILD_PROFILE=OFF -DCMAKE_C_COMPILER=/usr/local/myclang/bin/clang -DCMAKE_AR=/usr/local/myclang/bin/llvm-ar -DCMAKE_NM=/usr/local/myclang/bin/llvm-nm -DCMAKE_RANLIB=/usr/local/m...

Hello, on the problems cross-building compiler-rt: Tried to follow https://llvm.org/docs/HowToCrossCompileBuiltinsOnArm.html which lead to this cmake: cmake -G "Ninja" ../llvm/projects/compiler-rt/ -DCOMPILER_RT_BUILD_BUILTINS=ON -DCOMPILER_RT_BUILD_SANITIZERS=OFF -DCOMPILER_RT_BUILD_XRAY=OFF -DCOMPILER_RT_BUILD_LIBFUZZER=OFF -DCOMPILER_RT_BUILD_PROFILE=OFF -DCMAKE_C_COMPILER=/usr/local/myclang/bin/clang -DCMAKE_AR=/usr/local/myclang/bin/llvm-ar -DCMAKE_NM=/usr/local/myclang/bin/llvm-nm -DCMAKE_RANLIB=/usr/local/m...

I am currently trying to compile a pretty simple program to work on an experimental board. It contains an (FPGA-version of) an ARMv4 processor. So basically, I try this (on my Ubuntu 18.04.1 LTS): clang -v --target=arm-none-eabi -c barehello.c -o barehelloCLANG.o clang -v --target=arm-none-eabi -c io.c -o io.o clang -v --target=arm-none-eabi barehelloCLANG.o io.o -o helloCLANGstatic -static
