Can you provide us small reproducer? Sycl and oneMKL work in our test-case. You should not need to load any env, module load oneapi​ should do the trick on JLSE (and nothing required on sunspot).

If I don’t source /soft/restricted/CNDA/sdk/2022.10.15.001/oneapi/setvars.sh, then it can't find the mkl libraries and I get the error /usr/bin/ld: cannot find -lonemkl If I DO source it, then I get the Undefine error, but not the missing library. Am I sourcing the wrong setup file? thanks, Charles.
