[llvm-dev] Cross-compiling libc++ to linux-armv7hf gives undefined symbols in cmath / math.h

Hello,
I am trying to cross-compile libc++ from my x86_64 linux system to armv7hf.
We have our own gcc compiler that we build with crosstools-ng (based on gcc
6.3.0) and I set my environment like this:
CC=armv7a-plex-linux-gnueabihf-gcc
CXX=armv7a-plex-linux-gnueabihf-g++
CFLAGS=-fPIC -DPIC -mfloat-abi=hard -march=armv7-a -Os -mfpu=vfpv3-d16
--sysroot=<path>
CXXFLAGS=-fPIC -DPIC -mfloat-abi=hard -march=armv7-a -Os -mfpu=vfpv3-d16
--sysroot=<path>
LDFLAGS=-static-libgcc --sysroot=<path>
then run cmake:
cmake -GNinja -DLIBCXXABI_USE_LLVM_UNWINDER=ON DLLVM_TARGET_ARCH=ARM
-DLLVM_DEFAULT_TARGET_TRIPLE=arm-linux-gnueabihf
-DLLVM_TARGETS_TO_BUILD=ARM -DCMAKE_CROSSCOMPILING=True ..
This errors out as shown below. It's like it's missing some definitions of
different math functions that I can't seem to be able to see anywhere else.
Is this a known problem? Or is it something with my compiler / toolchain
setup that creates this problem?
Thanks for any assistance.
