Cześć Piotr,

I found this thread while trying to update the Debian packaging 
for a Python library that I maintain.  The library has Sphinx 
documentation that is quite complex to build:  First, the library 
needs to be built (it contains C extensions), then figures are 
generated by scripts, and finally Sphinx is run.  This is all done 
in a Makefile.

With “install target”, do you mean dh_installdocs?  In our 
debian/rules, we have now

# Make documentation only if needed.
ifneq "$(shell dh_listpackages | grep -- -doc)" ""
override_dh_installdocs:
	cd doc && PYTHONPATH=$(abspath 
	debian/python-kwant/usr/lib/python2.7/dist-packages) 
	$(MAKE) html
	dh_installdocs
endif

This seems to work, but is this what you meant?  Also, I have two 
questions:

• How to get rid of the explicit mention of python2.7?

• Is the “ifneq”-clause the proper way to ensure that 
  documentation is only built for binary-indep?

I have one further more general question with regard to Debian 
packaging with pybuild.  Pybuild deletes the *.egg-info directory 
but that directory is included in the tarball as made by “setup.py 
sdist”.  (I am aware that some people consider that directory to 
be generated data, but this is debatable [1], and it’s standard 
practice to include it in the tarball anyway.)  This has the 
consequence that after running “gbp buildpackage”, some files are 
missing and thus “gbp buildpackage” cannot be re-run without “git 
checkout .”.  This situation is unsatisfactory.  Is there a 
recommended solution?

The complete Debian packaging of our library is available in a git 
repository [2].

Thanks for any hints,
Christoph
