Error Building BLAS Fortran95 Interface

cpage — Sat, 09 Mar 2024 19:05:01 GMT

I am trying to build the BLAS Fortran95 interface with the ilp64 option using gfortran. I can successfully build the lp64 interface but when I call the Intel supplied makefile with the ilp64 interface option compilation fails with an error indicating there is no specific subroutine for the generic 'f77_axpby'. See posting below

Note that I am using the makefile provided in $(MKLROOT)/share/mkl/interfaces/blas95. What do I need to do to build the BLAS Fortran95 interface with the ilp64 option?

make libintel64 interface=ilp64 INSTALL_DIR=/home/cap/Documents/code/fortran FC=gfortran
make PLAT=lnx32e build interface=ilp64 MKLROOT=/home/cap/intel/oneapi/mkl/2024.0 INSTALL_DIR=/home/cap/Documents/code/fortran FC=gfortran

Hi Christopher,

Thank you for your question. We are trying to check the issue at our end by compiling the interface file.

Hi,

Can you use this link https://www.intel.com/content/www/us/en/developer/tools/oneapi/onemkl-link-line-advisor.html#gs.6fcu5r and choose "Fortran API with 64-bit integer" to build the interface?

There is the wrong path of source or include directory. If you see this message - 'There is no specific subroutine .... ' with compiling, which is almost uses wrong directory path. In this case, you missed to include directory. ( I can't see -I option) . "-I${F95ROOT}/include/mkl/intel64/ilp64 -fdefault-integer-8 -m64 -I"${MKLROOT}/include"" is need
