I need to set a path to fortan compiler in cmake, like
set(CMAKE_FC_COMPILER /bin/aarch64-none-linux-gnu-gfortran) set(CMAKE_Fortran_COMPILER /bin/aarch64-none-linux-gnu-gfortran)
cmake documentation is saying CMAKE_Fortran_COMPILER: https://cmake.org/cmake/help/latest/envvar/FC.html
but I see people CMAKE_FC_COMPILER: https://mixable.blog/how-to-set-c-c-or-fortran-compiler-for-cmake/
which one is correct and what is the difference?
CMAKE_FC_COMPILER isn't something I've ever come across. CMake's own documentation is trustworthy here, I don't see why it wouldn't be. I've used
CMAKE_Fortran_FLAGS and build a ton of HPC software for the clusters I manage.
The only references I find of real projects using
CMAKE_FC_COMPILER is to convert it to the proper
I need to set a path to fortan compiler in cmake
Or set the things during the configuration step, like
cmake .. -DCMAKE_Fortran_COMPILER=/bin/your_fort
Hardcoding guesses like this typically always just unnecessarily break things for everyone else (like anyone on a different OS, anyone in an HPC environment etc.).
