[petsc-users] --download-hdf5 and then compiling cgns

[Klaij, Christiaan]

Satish, Gaetan, thanks for your suggestions. I've decided not to
use cmake for cgns, and that works fine with petsc's build of
hdf5.

I have compiled CGNS3.3 with hdf from PETSc but not using cmake from CGNS. Here is what I used:

git clone  https://github.com/CGNS/CGNS.git

cd CGNS/src
export CC=mpicc
export FC=mpif90
export FCFLAGS='-fPIC -O3'
export CFLAGS='-fPIC -O3'
export LIBS='-lz -ldl'

./configure --with-hdf5=$PETSC_DIR/$PETSC_ARCH --enable-64bit --prefix=/u/wk/gkenway/.local  --enable-parallel --enable-cgnstools=yes --enable-shared
make -j 10

Hope that helps
Gaetan

--download-hdf5 uses 'autoconf' build of hdf5 - and not cmake
build. [hdf5 provides both build tools].

This must be the reason why hdf5Config.cmake and hdf5-config.cmake
files might be missing.

You might be able to install hdf5 manually with cmake - and then build
cgns-3.3.1 with it.
