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

Tue Oct 7 02:32:48 PDT 2014

After do "sudo apt-get update", the following are pass.

Install the dependencies:

    $ sudo apt-get install binutils clang-3.5 cmake gcc make

To cross-compile for ARM, install following dependencies as well:

    $ sudo apt-get install binutils-multiarch \
                           gcc-4.7-arm-linux-gnueabihf \
                           g++-4.7-arm-linux-gnueabihf

But now fail as follows,

cschen at debian:~/test/libcxx-scripts$ export CROSS_COMPILING=arm

Yeah, it would help to know more specifics about where you're getting stuck.

For my baremetal arm toolchain, I use buildit&testit for libc++abi, and
buildit&lit for libc++... Which is a bit different than what you'll get out of
using cmake for it. Also, I've customized both buildits, the testit, and
libc++'s lit config file to do this, and those changes are very specific to my
environment (I don't recommend using buildit/testit to build either library
unless you're working on porting them to a new platform. Even then, just do it
the "right way" with cmake, and don't be stupid like me ;] ).

Cheers,

Jon
