74. Building nwchem 6.1 on debian testing 32 bit only

EDIT 18 May 2012: 
It's now been solved on 64 bit as well
Compiling nwchem 6.1 with internal libs on debian: http://verahill.blogspot.com.au/2012/05/compiling-nwchem-61-with-internal-libs.html
Compiling nwchem 6.1 with openblas on debian: http://verahill.blogspot.com.au/2012/05/building-nwchem-61-on-debian.html


This doesn't work with the 64 bit version of nwchem 6.1. There's a separate post on that. Nwchem 6.1 64 bit will build just fine, but will crash when run. Again, see the other post.

Building on 32 bit debian testing:



Put a hold on your mpich2 and mpich2-dev packages (see e.g. here for more details)
1. edit your /etc/apt/sources.list to allow packages from stable e.g.

deb ftp://ftp.au.debian.org/debian/ testing main contrib non-fre
deb ftp://ftp.au.debian.org/debian/ stable main contrib non-free

2. create an /etc/apt/preferences file e.g.

Package: *
Pin: release a=testing
Pin-Priority: 990
Package: *
Pin: release a=stable
Pin-Priority: -10

2. install v 1.2 explicitly

sudo apt-get update && sudo apt-get install mpich2=1.2.1.1-5 libmpich2-dev=1.2.1.1-5

3. put a hold on the packages

sudo su
echo "mpich2 hold"|dpkg --set-selections
echo "libmpich2-dev hold"|dpkg --set-selections

exit

Make sure you have the necessary packages:
sudo apt-get install build-essential gfortran fort77

I had some error messages before installing fort77. Not sure they are related.

Download the nwchem source
cd ~
wget http://www.nwchem-sw.org/images/Nwchem-6.1-2012-Feb-10.tar.gz
tar -xvf Nwchem-6.1-2012-Feb.tar.gz
cd nwchem-6.1

create buildconf.sh in ~/nwchem-6.1


export LARGE_FILES=TRUE
export TCGRSH=/usr/local/bin/ssh
export NWCHEM_TOP=/home/me/nwchem-6.1
export NWCHEM_TARGET=LINUX
export NWCHEM_MODULES=all
export USE_MPI=y
export USE_MPIF=y
export USE_MPIF4=y
export MPI_LOC=/usr
export MPI_LIB=$MPI_LOC/lib
export MPI_INCLUDE=$MPI_LOC/include/mpich2
export LIBMPI="-lmpich -lfmpich -lpthread"
export NWCHEM_MODULES="all"
cd $NWCHEM_TOP/src
make clean
make nwchem_config
make FC=gfortran

run
sh buildconf.sh


Building takes ages. But it works. Why it works for 32 bit and not 64 bit has me a bit confused, but it's probably a good hint to the solution.
