Packages build against the reference cblas, but the others +are (by design) compatible, so we can force one to take precedence at +runtime with an ld.so.conf entry. But that only works when consumers +link to libcblas.so. If they link directly to (say) openblas, then +changing how libcblas.so resolves won't help. + +When Flint tries to find "cblas," it looks for accelerate and openblas +before plain cblas. That runs afoul of the scheme described above. To +remedy it, we patch the search function so that only "cblas" is +considered. Since virtual/cblas always pulls in the reference +implementation, there'd be no point in altering the search order to +consider e.g. openblas after cblas. +--- + CMake/FindCBLAS.cmake | 4 +--- + 1 file changed, 1 insertion(+), 3 deletions(-) + +diff --git a/CMake/FindCBLAS.cmake b/CMake/FindCBLAS.cmake +index f5b5b1c..f4919f4 100644 +--- a/CMake/FindCBLAS.cmake ++++ b/CMake/FindCBLAS.cmake +@@ -11,13 +11,11 @@ + find_path(CBLAS_INCLUDE_DIRS NAMES cblas.h + HINTS CBLAS_ROOT ENV CBLAS_ROOT + PATHS ${INCLUDE_INSTALL_DIR} ${CMAKE_INSTALL_PREFIX}/include +- PATH_SUFFIXES openblas cblas blis flexiblas + ) + +-find_library(CBLAS_LIBRARIES NAMES accelerate openblas cblas blas blis flexiblas ++find_library(CBLAS_LIBRARIES NAMES cblas + HINTS CBLAS_ROOT ENV CBLAS_ROOT + PATHS ${LIB_INSTALL_DIR} ${CMAKE_INSTALL_PREFIX}/lib +- PATH_SUFFIXES openblas cblas blis flexiblas + ) + + include(FindPackageHandleStandardArgs) +-- +2.41.0 + |
