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

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 Logan On Tue, Oct 7, 2014 at 5:32 PM, gamma_chen <gamma_chen at yahoo.com.tw> wrote:> After do
