[petsc-dev] Error compiling PETSc on Windows

[Hector E Barrios Molano]

Thanks Barry and Satish for your answers.

I installed the correct version of hypre. Also, I changed the paths to 
short dos paths as Satish suggested. Now PETSc compiles without problems 
and the tests are ok.

Regarding Satish notes:

I had to include -LIBS because otherwise the configure script stops 
while testing blas-lapack with the following error:

===============================================================================
TESTING: checkLib from 
config.packages.BlasLapack(config/BuildSystem/config/packages/BlasLapack.py:114)*******************************************************************************
          UNABLE to CONFIGURE with GIVEN OPTIONS    (see configure.log 
for details):
-------------------------------------------------------------------------------
You set a value for --with-blaslapack-lib=<lib>, but 
['-L/cygdrive/c/PROGRA~2/INTELS~1/COMPIL~1/windows/mkl/lib/intel64', 
'mkl_intel_lp64.lib', 'mkl_core.lib', 'mkl_intel_thread.lib'] cannot be used
*******************************************************************************

Do I need to turn on the MKL sparse functionality? what is the 
difference between MKL_SPARSE, MKL_SPARSE_OPTIMIZE and MKL_SPARSE_SP2M 
in the configure options?

Why is better to use sequential MKL? Is it possible to use a hybrid MPI 
- OpenMP approach? for example MPI for internode communication and 
OpenMP for intranode computation? In that case would it be good to use 
threaded MKL + MPI?

Thanks,

Hector
