I am compiling Fortran code with the ifx compiler (version 2025.0.4) on Windows. I have the Intel MKL library downloaded as well and I am trying to compile a program using it, like this:

ifx test.f90 -o test.exe -Qmkl

However, when I have this program:

include "mkl_blas.f90"
program main
    use BLAS95
    implicit none
    integer, parameter :: dp = selected_real_kind(15, 307)
    real(dp), dimension(2,2) :: A, B, C
    A = 1.0
    B = 1.0
    C = 0.0
    call gemm(A, B, C)
    write(*,*) C
end program main

it gives me linker error LNK2019, unrecognised extern symbol DGEMM_F95.

However, if I use the old dgemm function with all the arguments instead of the generic gemm,

call dgemm("N", "N", 2, 2, 2, 1.d0, A, 2, B, 2, 0.d0, C, 2)

everything works perfectly. What is happening here? I thought that using blas95 was enough to get the generic versions.
