Bugzilla Automation <bugzi...@freebsd.org> has asked freebsd-kde (Team) <k...@freebsd.org> for maintainer-feedback: Bug 270954: devel/cmake-core: lots of armv7 build failures with "No SOURCES given to target" https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=270954
--- Description --- Many ports fail on armv7 with the same class of error message: -- Detecting CXX compile features -- Detecting CXX compile features - done CMake Error at /wrkdirs/usr/ports/graphics/pfstools/work/.build/CMakeFiles/CMakeTmp/CMakeLists .txt:14 (add_executable): No SOURCES given to target: cmTC_7730d CMake Error at /usr/local/share/cmake/Modules/FindOpenMP.cmake:261 (try_compile): Failed to generate test project build system. Call Stack (most recent call first): /usr/local/share/cmake/Modules/FindOpenMP.cmake:537 (_OPENMP_GET_FLAGS) CMakeLists.txt:39 (find_package) -- Configuring incomplete, errors occurred! See also "/wrkdirs/usr/ports/graphics/pfstools/work/.build/CMakeFiles/CMakeOutput.log". *** Error code 1 This affects at least the following ports (tested on 2023Q2): graphics/oyranos audio/fluidsynth cad/gmsh science/gromacs math/cimod lang/halide games/regoth misc/openmvg cad/FreeCAD graphics/cloudcompare math/blaze science/gnudatalanguage graphics/pfstool Without having investigated this at all, the cause may be connected with LLVM not supporting OpenMP on armv6/armv7. The offending file FindOpenMP.cmake is installed by devel/cmake-core. Unfortunately I am not very familiar with cmake and don't really have any idea on what the cause could be.
