[petsc-users] configuration option for PETSc on cluster

[Samuel Lanthaler]

Dear Satish and Stefano,

Thank you for your answers. I believe I had initially tried to use the 
option --with-blaslapack-dir=[...], instead of specifying lib and 
include directly. But that gives me an error message:

*******************************************************************************
          UNABLE to CONFIGURE with GIVEN OPTIONS    (see configure.log 
for details):
-------------------------------------------------------------------------------
You set a value for --with-blaslapack-dir=<dir>, but 
/opt/intel/compilers_and_libraries_2017.4.196/linux/mkl cannot be used
*******************************************************************************

I attach the new configure.log. Do you think there is something wrong 
with the mkl version that I'm trying to use? Or is it only related to petsc?

Cheers,
Samuel
