MKL 2024.2 doesn't work with CMake

V-T — Fri, 16 Aug 2024 15:28:21 GMT

Consider the following contents of two files in the same directory:

`CMakeLists.txt`:

cmake_minimum_required(VERSION 3.12) project(test Fortran) set(MKL_ARCH "intel64") set(MKL_LINK "dynamic") set(MKL_THREADING "sequential") set(MKL_INTERFACE "lp64") set(MKL_MPI "intelmpi") find_package(MKL) add_executable(test test.f90) target_link_libraries(test ${MKL_LIBRARIES})

`test.f90`:

program p real sdot print*,sdot(1,[1.],1,[1.],1) end

An attempt to compile the program with the following commands in the same directory

mkdir build cd build FC=mpiifx cmake .. cmake --build .

results in an error `undefined reference to `sdot_'`.

It only happens with the newest MKL version 2024.2. The older MKL version 2024.1 works properly. Did something important change in the `MKLConfig.cmake` file? Am I missing something in the `CMakeLists.txt` file?

Hi,

From oneMKL 2024.2, we recommend users use MKL::MKL instead of MKL_LIBRARIES in target_link_libraries(test MKL::MKL)

Please use MKL::MKL target. You can also find an example in the oneMKL CMake documentation page.

Regards,

Ruqiu
