[Bug 1941786] [NEW] OpenMPI 4.0.3 forgets to link open-pal
Public bug reported: Hi, I am trying to compile a C++ program with CMake 3.16.3 on Ubuntu 20.04 LTS, which ships OpenMPI 4.0.3. I realized that the mpic++ --showme:link flags forget to link `-lopen-pal`, which is part of the OpenMPI lib dir. -pthread -L/usr/lib/x86_64-linux-gnu/openmpi/lib -lmpi_cxx -lmpi Following that, a CMake CXX program compiled with clang++ that checks for `find_package(MPI REQUIRED)` will error out with: ``` -- Found MPI_C: /usr/lib/x86_64-linux-gnu/openmpi/lib/libmpi.so (found version "3.1") -- Could NOT find MPI_CXX (missing: MPI_CXX_WORKS) CMake Error at /usr/local/share/cmake-3.21/Modules/FindPackageHandleStandardArgs.cmake:230 (message): -- Configuring incomplete, errors occurred! Could NOT find MPI (missing: MPI_CXX_FOUND CXX) (found version "3.1") ``` The reason for that is in the compile check ``` /opt/rocm/llvm/bin/clang++ -pthread CMakeFiles/cmTC_abf94.dir/test_mpi.cpp.o -o cmTC_abf94 -Wl,-rpath,/usr/lib/x86_64-linux-gnu/openmpi/lib /usr/lib/x86_64-linux-gnu/openmpi/lib/libmpi_cxx.so /usr/lib/x86_64-linux-gnu/openmpi/lib/libmpi.so ld.lld: error: /usr/lib/x86_64-linux-gnu/openmpi/lib/libmpi_cxx.so: undefined reference to opal_class_init_epoch [--no-allow-shlib-undefined] ld.lld: error: /usr/lib/x86_64-linux-gnu/openmpi/lib/libmpi_cxx.so: undefined reference to opal_list_item_t_class [--no-allow-shlib-undefined] ld.lld: error: /usr/lib/x86_64-linux-gnu/openmpi/lib/libmpi_cxx.so: undefined reference to opal_class_initialize [--no-allow-shlib-undefined] ld.lld: error: /usr/lib/x86_64-linux-gnu/openmpi/lib/libmpi_cxx.so: undefined reference to opal_uses_threads [--no-allow-shlib-undefined] ``` where the linker refuses the missing lib and fails the check. The solution to this is to make sure that mpic++ --showme:link appends -lopen-pal as well. User-side work-around until fix is applied: export LDFLAGS="-lopen-pal" ** Affects: openmpi (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1941786 Title: OpenMPI 4.0.3 forgets to link open-pal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openmpi/+bug/1941786/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1865091] [NEW] Backport broken scatter/gather Signatures
Public bug reported: Ubuntu 18.04 LTS ships CUDA 9.1.85 which is broken with provided GCC compilers in a slightly complex way. By default, the g++ compiler version is 7.4.0, which is not supported by CUDA/NVCC 9.1.85. Next, CUDA/NVCC 9.1.85 should have provided support for g++ 6. But the release overlooked an incompatibility with std::tuple which renders this compiler combination not useful either: https://gist.github.com/ax3l/9489132 Consequently, users that want to use mature C++11/14 features can still switch to install a g++-5 package on Ubuntu 18.04 but this compiler has another set of bugs in signatures of gather/scatter intrinsics which were fixed in later GCC releases.

[Bug 1706326] [NEW] Clang CUDA Support Failing
Public bug reported: Hi, clang 3.9+ supports compiling CUDA C++ files (.cu): http://llvm.org/docs/CompileCudaWithLLVM.html#prerequisites I installed the packages - clang-3.9 - nvidia-cuda-toolkit (8.0) on Ubuntu 16.04 (via the latest docker image: ubuntu:16.04). My example file is just any .cu file, e.g. this one: https://github.com/ax3l/cpp_snippets/blob/master/cuda_mandelbrot/mandelbrot.cu If I now run clang++ main.cu or clang++ --cuda-path=/usr main.cu I get the error clang: error: cannot find CUDA installation. Provide its path via --cuda-path, or pass -nocudainc to build without CUDA includes. This is the same bug as reported upstream in https://bugs.llvm.org/show_bug.cgi?id=26966 due to the "scattered install" of CUDA in Debian/Ubuntu. Is there a way to fix this from the packaging side? ** Affects: clang (Ubuntu) Importance: Undecided Status: New ** Affects: nvidia-cuda-toolkit (Ubuntu) Importance: Undecided Status: New ** Tags: clang cuda ** Also affects: nvidia-cuda-toolkit (Ubuntu) Importance: Undecided Status: New ** Summary changed: - CUDA Support Failing + Clang CUDA Support Failing -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1706326 Title: Clang CUDA Support Failing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/clang/+bug/1706326/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
