Thank you! I can build arm libcxx.so and compile it now. I want to run it with qemu further but fail as below. Do you know how to run the compiled code on qemu.
cschen at debian:~/test/libcxx-scripts$ clang++ -target arm-linux-gnueabihf -mcpu=cortex-a9 -mfloat-abi=hard -mfpu=neon -isystem out-arm/include -isystem out-arm/include/c++/v1 -isystem /usr/arm-linux-gnueabihf/include -Lout-arm/lib -lc++ -lpthread -lc++abi -lm -lc -lgcc_s -lgcc hello-world.cpp -o aa
cschen at debian:~/test/libcxx-scripts$ ./aa
bash: ./aa: cannot execute binary file
cschen at debian:~/test/libcxx-scripts$ qemu-arm aa
Best regards
cschen

Hi cschen,
It seems that libunwind (the one included in libcxxabi) is mandatory at the moment.
Use the second build command instead:
$ CROSS_COMPILING=arm ENABLE_LIBUNWIND=1 ./scripts/compile-all.sh
