This is solved, see below.
Thanks for this great product. I'm new here, but I'm already finding it very useful.
I encontered a problem when trying to use the python integration.
The steps to reproduce are the following
cd basilisk/src/
make stream.py
The same happens when manually creating stream.c elsewhere.
The error is the following
$ make stream.py

This is a docker container, but I don't think the problem is related with docker.
I did the installation using wget, on 2018-oct-10. By the way, how can I get a specific tag of the code using wget?
---------------
UPDATE:
If I copy this file http://basilisk.fr/src/navier-stokes/stream.i to my local directory, the error is different.
swig -I/home/dd22/basilisk/src -python stream.i
No module name specified using %module or -module.

UPDATE [SOLVED]:
I didn't say before, the OS is debian/stretch. I solved this problem with
apt-get install libpython2.7-dev python-numpy python-matplotlib
Moreover, since the is no display in my container, it was also necessary to
export MPLBACKEND=Agg
and to add plt.savefig("{}.png".format(i)) to the graph function.
