[petsc-users] PETSC configuration on linux with intel MKL

[Satish Balay]

This syntax is useful for python - for ex.: config/examples*.py

Best to use shell friendly notation - when not using python scripts. i.e.:

--with-blaslapack-lib="/opt/intel/oneapi/mkl/2025.0/lib/intel64/libmkl_blas95_lp64.a /opt/intel/oneapi/mkl/2025.0/lib/intel64/libmkl_lapack95_lp64.a /opt/intel/oneapi/mkl/2025.0/lib/intel64/libmkl_gf_lp64.a /opt/intel/oneapi/mkl/2025.0/lib/intel64/libmkl_sequential.a /opt/intel/oneapi/mkl/2025.0/lib/intel64/libmkl_core.a" 

or

--with-blaslapack-lib="-L/opt/intel/oneapi/mkl/2025.0/lib/intel64/ -lmkl_lapack95_lp64 -lmklblas95_lp64 -lmkl_gf_lp64 -lmkl_sequential -lmkl_lapack95_lp64"

Also "--with-blaslapack-dir=/opt/intel/oneapi/mkl/2025.0/lib/intel64" should automatically find and give something like:

BlasLapack:
