[LLVMdev] Can libc++ build for arm cross compiler?

[gamma_chen]

Logan and Richard,
Thank your quick and kindly help. I am busy with something else today and will try these script tomorrow.
Best regards

 Hi cschen,

Here are the test scripts which I written when I was developing ARM exception handling support:
https://github.com/loganchien/libcxx-scripts

The script should work on Debian wheezy (cross-compiling from amd64 to armhf.)

In general, here are the necessary steps:
1. Get a working arm-linux-gnueabihf gcc/g++ toolchain (for the headers and libraries)
2. Setup the include search path (e.g. /usr/arm-linux-gnueabihf/include)
3. Compile with correct compiler/linker flags (e.g. -target arm-linux-gnueabihf and some cmake tricks)

Feel free to let me know if you have encountered any problem.

Sincerely,
Logan

  The following web say the libc++abi is ready on arm. http://libcxxabi.llvm.org/spec.html 
  I try to build libc++ and libc++abi for host x86_64(linux) and target arm(linux) but fail. I have read the web http://llvm.org/docs/HowToCrossCompileLLVM.html 
  Does anyone know whether it's available for my need? If you know how to build, what is the build options you use? 
  
 I use libc++ and libc++abi (as well as compiler-rt) for the ELLCC cross compilation tool chain project (http://ellcc.org). I use makefiles to build the libc++ stuff, which are pretty dependent on being used in an ELLCC environment. You can get pre built binaries from ftp://ellcc.org/pub. The tarballs contain pre built libraries for ARM (as well as Mips, x86, PowerPC, and semi-functional Microblaze).
