[llvm-dev] cannot build CUDA support with llvm-trunk

[Siegmar Gross via llvm-dev]

Hi,

I try to build the latest version of llvm-trunk with Cmake (gcc-5.3.0
is necessary for CUDA) on my "SUSE Linux Enterprise Server 12.2 (x86_64)".
Unfortunately, "libomptarget" for CUDA will not be built with that
version. I use the same configuration command as before.


cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr/local/${LLVM_VERSION} \
   -DCMAKE_BUILD_TYPE:STRING="Release" \
   -DLLVM_PARALLEL_COMPILE_JOBS:STRING="4" \
   -DLLVM_PARALLEL_LINK_JOBS:STRING="4" \
   -DCMAKE_C_COMPILER:STRING="${DIRPREFIX_PROG}/${GCCDIR}/bin/gcc" \
   -DCMAKE_C_FLAGS:STRING="-m64 -I/usr/local/valgrind/include" \
   -DCMAKE_CXX_COMPILER:STRING="${DIRPREFIX_PROG}/${GCCDIR}/bin/g++" \
   -DCMAKE_CXX_FLAGS:STRING="-m64 -I/usr/local/valgrind/include" \
   -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 \
   ../llvm \
   |& tee log.cmake


Now I get the following output.

loki build 613 tail -13 log.cmake

Do you have any ideas why I cannot build CUDA support any longer? Is it
necessary to change my configuration command to build CUDA support?
Thank you very much for any help in advance.


Kind regards
