Hi,
I tried to build the latest version of llvm-trunk with Cmake (gcc-6.4.0
is necessary for CUDA-9.0) on my "SUSE Linux Enterprise Server 12.2
(x86_64)".
Unfortunately I got an error with the following configuration, because
"pthread_atfork" wasn't defined.
set LLVM_VERSION=llvm-trunk
cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr/local/${LLVM_VERSION} \
-GNinja \
-DLLVM_TARGETS_TO_BUILD:STRING="NVPTX;X86" \
-DCMAKE_BUILD_TYPE:STRING="Release" \
-DLLVM_PARALLEL_COMPILE_JOBS:STRING="4" \
-DLLVM_PARALLEL_LINK_JOBS:STRING="4" \
-DCMAKE_C_COMPILER:STRING="/usr/local/gcc-6.4.0/bin/gcc" \
-DCMAKE_C_FLAGS:STRING="-m64 -I/usr/local/valgrind/include
-I/usr/include/ncurses" \
-DCMAKE_CXX_COMPILER:STRING="/usr/local/gcc-6.4.0/bin/g++" \
-DCMAKE_CXX_FLAGS:STRING="-m64 -I/usr/local/valgrind/include
-I/usr/include/ncurses" \
-DCMAKE_EXE_LINKER_FLAGS:STRING="-m64" \
-DLLVM_LIBDIR_SUFFIX:STRING="64" \
-DLLVM_POLLY_LINK_INTO_TOOLS:BOOL=ON \
-DLIBOMPTARGET_DEP_LIBELF_INCLUDE_DIR:STRING="/usr/local/elfutils-0.169/include"
\
-DLIBOMPTARGET_DEP_LIBELF_LIBRARIES:STRING="/usr/local/elfutils-0.169/lib64/libelf.so"
\
-DLIBOMPTARGET_DEP_LIBFFI_INCLUDE_DIR:STRING="/usr/include" \
-DLIBOMPTARGET_DEP_LIBFFI_LIBRARIES:STRING="/usr/lib64/libffi.so" \
-DCUDA_INCLUDE_DIRS:STRING="/usr/local/cuda/include" \
-DCUDA_LIBRARIES:STRING="/usr/local/cuda/lib64/libcudart.so" \
-DBUILD_SHARED_LIBS:BOOL=ON \
-DOPENMP_ENABLE_LIBOMPTARGET:BOOL=On \
../llvm \
|& tee log.cmake
ninja |& tee log.ninja-build
I was able to build the project after adding the following lines to the
configuration command.
-DCMAKE_C_STANDARD_LIBRARIES="-lpthread" \
-DCMAKE_CXX_STANDARD_LIBRARIES="-lpthread" \
Can somebody add the library to the default configuration files? Thank you
very much for any help in advance.
Kind regards
Siegmar
