[petsc-users] PETSc and some external libraries configured with CMake?

[paul zhang]

Jed,

Thanks for your consistent help Bro. I wish I could help you or the
community back in some way.

I am developing a CFD code on the cluster of my university. My code calls
for PETSc to solve the linear solver, and it uses ParMetis and CGNS
libraries. I once configured the whole code (my source code, the needed
libraries above, etc) with CMake, back then the PETSc version is 3.1-p8.
After I updated the PETSc to the newest, it never worked with me. It got me
a couple of weeks to figure out what is the real reason.  One of the reason
I guess is that I have to use the mpi compiler from the cluster.  There is
nothing wrong with the installation guide on the PETSc website. The issue
is it does not work with me (maybe only with me). The other is I have add
the valgrind include dir and lib to my previous CMakeList, since it is
necessary for the new PETSc.

The FindPETSc.cmake you wrote works pretty good if I just want to use
PETSc. Well, it is my problem (or maybe fault) again since I used
old fashioned cmake and I have to call some other libraries besides PETSc.



Attached is my script to install PETSc. Maybe it helps to the others.

#!/bin/sh

export PETSC_DIR=`pwd`
export PETSC_ARCH=linux-gnu-intel

MKLPATH=/share/cluster/RHEL6.2/x86_64/apps/intel/ict/composer_xe_2013.0.079/mkl/lib/intel64
VALGRINDPATH=/share/cluster/RHEL6.2/x86_64/apps/valgrind/3.9.0
HDF5PATH=/share/cluster/SLES9/x86_64/apps/hdf5/1.8.3


./configure --configModules=PETSc.Configure
--optionsModule=PETSc.compilerOptions --with-blas-lapack-dir=$MKLPATH
-lf2clapack -lf2cblas --COPTFLAGS=-O3 --CXXOPTFLAGS=-O3 --with-debugging=1
--with-precision=double  --with-shared-libraries --with-x=no --with-x11=no
--with-mpi=1
--with-mpi-dir="/share/cluster/RHEL6.2/x86_64/apps/openmpi/1.6.2"
--with-valgrind-dir=$VALGRINDPATH  --download-metis --download-parmetis
--with-hdf5-dir=$HDF5PATH

Best,
Paul
