[llvm-dev] LLVM cross compilation for arm target

[Balasaheb Dabhade via llvm-dev]

Hello All,

I am building llvm-clang tool chain for *arm target* by following the steps
from
http://clang.llvm.org/docs/CrossCompilation.html

*However when I tried following cmake command for build tool chain it gives
the error message :*

#CC='clang' CXX='clang++' cmake -G Ninja /home/iiita/llvm-exp/llvm
-DCMAKE_CROSSCOMPILING=True
-DCMAKE_INSTALL_PREFIX=/home/iiita/llvm-exp/llvm/build
-DLLVM_TABLEGEN=/usr/bin/host/llvm-tblgen
-DCLANG_TABLEGEN=/usr/bin/host/clang-tblgen
-DLLVM_DEFAULT_TARGET_TRIPLE=arm-linux-gnueabihf -DLLVM_TARGET_ARCH=ARM
-DLLVM_TARGETS_TO_BUILD=ARM -DCMAKE_CXX_FLAGS='-target
armv7a-linux-gnueabihf -mcpu=cortex-a9
-I/usr/arm-linux-gnueabihf/include/c++/4.7.1/arm-linux-gnueabihf/
-I/usr/arm-linux-gnueabihf/include/ -mfloat-abi=hard -ccc-gcc-name
arm-linux-gnueabihf-gcc'


*error :*

CMake Error at cmake/modules/CheckCompilerVersion.cmake:38 (message):
  Host Clang must be able to find libstdc++4.7 or newer!
Call Stack (most recent call first):
  cmake/config-ix.cmake:14 (include)
  CMakeLists.txt:412 (include)

I have installed libstdc++4.7-dev library but still same issue is coming.

Does anyone know how to resolve this issue?

Thanks,
Bala
