Good.

How is that related to your problem?

Yes, there are plans.  There currently is no documentation, because we
wanted to find a solution that would cover GPGME as well as all
bindings.  Last year we spoke about that at one of our hackathons, and
decided to give Sphinx a shot.

Help is always needed.  However, the first step is to integrate Sphinx
in our build system.  If you feel up to that, great!  We'd need a DCO
From you.  If you wanted to write documentation, also great, but that is
not what we need right now.


Cheers,
Justus

Thank you Justus for your advice, I could fix that and use the lib
from Python. I had not realized that both gpg and gpg2 are installed
by default on Ubuntu 16.04 LTS.

Do you know if there is any plan to better document the python
bindings in the GPGME doc? I may be able to help with that if needed.

Cheers,
Jean-François

Hi,

Thanks for your advice, I could fix that and use the lib from Python.

Do you know if there is any plan to better document the python bindings in
the GPGME doc? I may be able to help with that if needed.

gpgme_pubkey_algo_string is new in GPGME 1.7.  This suggests that the
version 1.8 that you built is not picked up.  How you resolve that is
really up to you and your needs.  You could for example add the
$your_install_prefix/lib to LD_LIBRARY_PATH in your bin/activate script.
