Hello @smeenai , this commit causes LLVM to fail to build when set set `-D
BUILD_SHARED_LIBS=ON`. Here is the failing CMake and Ninja invocation:
/tools/build/cmake-3.14.5/bin/cmake \
-G Ninja \
-D CMAKE_MAKE_PROGRAM=/tools/build/ninja-1.9.0/ninja \
-D CMAKE_C_COMPILER=/usr/lib/llvm-7/bin/clang \
-D CMAKE_CXX_COMPILER=/usr/lib/llvm-7/bin/clang++ \
-D CMAKE_BUILD_TYPE=Release \
-D CMAKE_INSTALL_PREFIX=/work/upstream/install \
-D LLVM_TOOL_CLANG_BUILD=ON \
-D LIBCXX_INCLUDE_BENCHMARKS=ON \
-D BUILD_SHARED_LIBS=ON \
-D LLVM_ENABLE_ASSERTIONS=ON \
-D LLVM_TARGETS_TO_BUILD=X86 \
/work/upstream/llvm-project/llvm
/tools/build/ninja-1.9.0/ninja -v install
I am able to successfully build LLVM when I change to `-D
BUILD_SHARED_LIBS=OFF`.
The outputted errors happen during link time of `lib/libclang_shared.so.9svn`:
