Hello Christian, I'd expect that adding the library paths (-L) from gcc -v should fix the unable to find -lc, -lm but it won't fix the -lclang_rt.builtins-armv6m.a . To get clang_rt.builtins-armv6m.a you will need to cross compile compiler-rt for v6m and copy it to /usr/local/myclang/lib/clang/8.0.0/lib/baremetal . Beware that building compiler-rt for v6m does need quite a bit of fighting cmake (https://llvm.org/docs/HowToCrossCompileBuiltinsOnArm.html). Your alternative if you already have a libgcc.a is to use --nostdlib or --nodefaultlibs to stop the driver adding -lm -lc -lc...

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

When I build llvm using llvm/clang as opposed to gcc I get the following: configure:2921: $? = 0 configure:2928: /home/rkotler/myclang/bin/clang++ -V >&5 clang: error: argument to '-V' is missing (expected 1 value) clang: error: no input files configure:2931: $? = 1 configure:2934: checking whether we are using the GNU C++ compiler
