From 8527dbbf4443daf3b43f3b1543192c3a2f26be80 Mon Sep 17 00:00:00 2001 From: Jakub Benda Date: Sat, 4 May 2019 10:38:02 +0100 Subject: FindBLAS: Use Intel fortran interface on OS X even with GNU Fortran According to Intel MKL Link Line Advisor, there is no GNU Fortran interface library provided for OS X variant of Intel MKL. Because of this missing library, FindBLAS was failing on OS X, looking for nonexistent library libmkl_gf_[i]lp64. To prevent this, FindBLAS will now always use Intel Fortran interface for MKL on OS X (libmkl_intel_[i]lp64), even with GNU Fortran. --- Modules/FindBLAS.cmake | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/Modules/FindBLAS.cmake b/Modules/FindBLAS.cmake index 77e689f..8d55ac7 100644 --- a/Modules/FindBLAS.cmake +++ b/Modules/FindBLAS.cmake @@ -239,7 +239,8 @@ if (BLA_VENDOR MATCHES "Intel" OR BLA_VENDOR STREQUAL "All") set(BLAS_mkl_DLL_SUFFIX "_dll") endif() else() - if(CMAKE_Fortran_COMPILER_LOADED AND CMAKE_Fortran_COMPILER_ID STREQUAL "GNU") + # Switch to GNU Fortran support layer if needed (but not on Apple, where MKL does not provide it) + if(CMAKE_Fortran_COMPILER_LOADED AND CMAKE_Fortran_COMPILER_ID STREQUAL "GNU" AND NOT APPLE) set(BLAS_mkl_INTFACE "gf") set(BLAS_mkl_THREADING "gnu") set(BLAS_mkl_OMP "gomp") -- cgit v0.12
