[LLVMdev] Lib C++ buildbot problem
...++ buildbot on ARM and I found an
inconsistency which I'm not sure how to fix.
I got a build error like this:
libc++abi.so: undefined reference to `_Unwind_GetGR'
Since I expected that the symbol would be provided by that library, I
searched the CMake on libc++abi and found this:
option(LIBCXXABI_USE_LLVM_UNWINDER "Build and use the LLVM unwinder." OFF)
...
if (LIBCXXABI_USE_LLVM_UNWINDER)
add_subdirectory(src/Unwind)
endif()
But on the Libc++AndAbiBuilder, there's no way to set the CMake
argument (or is there?):
def getLibcxxAndAbiBuilder(f=None, env={}, additional_features=set()):

Building LLVM with LLVM with no dependence on GCC
Thus wrote David Demelier via llvm-dev:

Building LLVM with LLVM with no dependence on GCC
Hi folks!
I'm trying to get rid of any dependency on libgcc*, but without success so
far. The following commands were executed on a freshliy installed and updated
Ubuntu 16.04 LTS:
=== snip ===
sudo apt-get install build-essential libffi-dev cmake # see aptget.txt for packages installed
sudo mv /usr/local /usr/local.orig
git clone https://github.com/llvm/llvm-project.git
cd llvm-project; git
