Output of build command
Using Clang built from an earlier trunk checkout there is a segmentation fault
when building lib/IR/CMakeFiles/LLVMCore.dir/AutoUpgrade.cpp.o.
Output from build in attachment.
I configured using
LLVM_ROOT=/home/arrow/tmp/clang/llvm
PROJECTS_ROOT=$LLVM_ROOT/projects
CC=clang CXX=clang++ \
cmake \
-DCMAKE_C_COMPILER=clang \
-DCMAKE_CXX_COMPILER=clang++ \

-DLIBCXXABI_LIBCXX_PATH=$PROJECTS_ROOT/libcxx \
-DLIBCXX_CXX_ABI_INCLUDE_PATHS=$PROJECTS_ROOT/libcxxabi/include \
../llvm
I build using
cmake --build . --config Release
There are previous version of Clang, libcxx and libcxxabi installed.
`clang --version` reports
clang version 4.0.0 (trunk 276574)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/local/bin
I'm on a fully update Ununtu 16.04 system.</pre>
