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

[Bruno Ramon Batista Fernande]

Hi Satish,
Thank you for your prompt response.
It seems like it doesn't reach the point of writing the configure.log for
this issue.
The command used is below. I am using mpich and oneAPI both installed from
apt from Ubuntu.

./configure --with-cc=mpicc --with-cxx=mpicxx --with-fc=mpif90
--with-debugging=0 --download-hypre
--with-blaslapack-libs=["/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"]
--with-scalapack-libs=["/opt/intel/oneapi/mkl/2025.0/lib/intel64/libmkl_scalapack_lp64.a","/opt/intel/oneapi/mkl/2025.0/lib/intel64/libmkl_blacs_lp64.a"]
--with-scalapack-include=/opt/intel/oneapi/mkl/2025.0/include

Best regards,
Bruno
