6.8.1

See /usr/local/shared/ubuntu-18.04/x86_64/nwchem/6.8.1/build-nwchem-atlas.sh and /usr/local/shared/ubuntu-18.04/x86_64/nwchem/6.8.1/test-nwchem.sh . The QA suite that ships with nwchem contains many, many failing tests but the test script used here contains only the ones the nwchem developers use themselves.

#module add mpi/openmpi/64/gnu/1.6.5

$NWCHEM_TOP/contrib/distro-tools/getmpidefs_nwchem # and then execute the result
# You may need to add -Wl,-rpath -Wl,/path/to/your/openmpi/lib too MPI_LIB too
#export LIBMPI="-lmpi_f90 -lmpi_f77 -lmpi -ldl -Wl,--export-dynamic -lnsl -lutil"

export PYTHONVERSION=2.7
export USE_PYTHON64=y
export PYTHONLIBTYPE=so
export PYTHON_SYSLIB=/usr/lib
export PYTHONCONFIGDIR=config-x86_64-linux-gnu
vim src/config/makefile.h

find the PYTHON64 bit and change $(PYTHONHOME)/lib64/python$(PYTHONVERSION)/config-x86_64-linux-gnu/libpython$(PYTHONVERSION).$(PYTHONLIBTYPE) to $(PYTHONHOME)/lib/python$(PYTHONVERSION)/config-x86_64-linux-gnu/libpython$(PYTHONVERSION).$(PYTHONLIBTYPE)

cd $NWCHEM_TOP/src
make nwchem_config
make

export NWCINS=/whereever
mkdir $NWCINS
mkdir $NWCINS/bin
mkdir $NWCINS/data
mkdir $NWCINS/contrib
cd $NWCHEM_TOP
cp -r contrib/python $NWCINS/contrib
cp bin/$NWCHEM_TARGET/nwchem $NWCINS/bin
chmod 755 $NWCINS/bin 
cd $NWCHEM_TOP/src/basis
cp -r libraries $NWCINS/data
cd $NWCHEM_TOP/src/
cp -r data $NWCINS
cd $NWCHEM_TOP/src/nwpw
cp -r libraryps $NWCINS/data
chmod -R go+rX $NWCINS

Make a $NWCINS/data/default.nwchemrc file containing this (expand the vars)

nwchem_basis_library $NWCINS/data/libraries/
nwchem_nwpw_library $NWCINS/data/libraryps/
ffield amber
amber_1 $NWCINS/data/amber_s/
amber_2 $NWCINS/data/amber_q/
amber_3 $NWCINS/data/amber_x/
amber_4 $NWCINS/data/amber_u/
spce $NWCINS/data/solvents/spce.rst
charmm_s $NWCINS/data/charmm_s/
charmm_x $NWCINS/data/charmm_x/

You need the module for nwchem to link the default.nwchemrc to ~/.nwchemrc
