[PETSC #16590] PETSc on Dual Opteron Cluster

[amjad ali]

Hello all in PETSc team and others,

I tried to install/configure PETSc 2.3.3-p5 on my FC6 desktop computer.
Following Happend:

[petsc1 at localhost petsc-2.3.3-p5]$ ./config/configure.py --with-cc=gcc
--with-fc=gfortran --with-cxx=g++ --download-f-blas-lapack=1
--download-mpich=1 --with-scalar-type=complex --with-clanguage=cxx
=================================================================================
             Configuring PETSc to compile on your
system
=================================================================================
TESTING: configureLibrary from config.packages.BlasLapack
(python/BuildSystem/con*********************************************************************************
         UNABLE to CONFIGURE with GIVEN OPTIONS    (see configure.log for
details):
---------------------------------------------------------------------------------------
Error downloading fblaslapack.tar.gz requested with -with-f-blas-lapack
option
*********************************************************************************

How to tackle this situation?

At the moment I want to develop & run PARALLEL codes on my FC6 Desktop
(single machine). Should I use the option --download-mpich=1 or
--download-mpich=0

Regards to All.
Amjad Ali.
