# If not done yet, certain python packages must be installed in a dynamico-only conda environment of yours :
#   conda create -n dynamico python
#   source activate dynamico
#   pip install scipy mpi4py jinja2 matplotlib cython cmake

# netCDF4 must be installed manually in order to use the netCDF library from the modules (requires Cython, see above)
# for unpack Python/extern/netCDF4-1.2.9.tar.gz then
#   LDFLAGS='-lirc' python setup.py build
#   cp -pr build/lib.linux-x86_64-2.7/net* ~/.conda/envs/dynamico/lib/python2.7/site-packages/
# NOTE : libirc.so is the intel runtime library and is needed at runtime.
# FIXME : python setup.py install does not seem to install anything, hence 'cp -pr ...'. There must be a better way.

# CICLAD does not have a parmetis module
# compiling parmetis uses cmake, installed above using pip because the system-wide cmake might not work with the modules
# for this unpack Python/extern/parmetis-4.0.3.tar.gz then
#   make config shared=1 prefix=$HOME/.conda/envs/dynamico
#   make install
# manually install libmetis.so and metis.h ...
#   cp $(find . -name 'libmetis.so') $HOME/.conda/envs/dynamico/lib/
#   cp $(find . -name 'metis.h') $HOME/.conda/envs/dynamico/include/
