[Nix-dev] Gajim and OMEMO

[Christoph-Simon Senjak]

Hi.

Has anyone managed to install Gajim with OMEMO-Support? I installed 
gajim with the plugin-manager (which I had to install manually), as 
apparently plugins are not packaged. Now, I normally use stable, that 
is, 16.09.1772.6e17350. When trying to activate the OMEMO plugin, it 
complains that I have to install python-axolotl. I tried the following 
in my ~/.nixpkgs/config.nix:

   packageOverrides = pkgs: rec {
       gajim_ = pkgs.stdenv.lib.overrideDerivation pkgs.gajim (old : {
         extraPythonPackages = with pkgs.pythonPackages; [ cryptography 
python-axolotl python-axolotl-curve25519 qrcode python-axolotl ];
       });

...

     });

and it runs and compiles, but still, I cannot activate the OMEMO plugin. 
Then I tried to use a shell and use the unstable tree, with the 
following default.nix:

with import (builtins.toPath (builtins.getEnv "HOME" + 
"/nobackup/nixos-unstable/nixpkgs")) {};
runCommand "bash"
{
    gajim_ = pkgs.stdenv.lib.overrideDerivation pkgs.gajim (old : {
         extraPythonPackages = with pkgs.pythonPackages; [ cryptography 
python-axolotl python-axolotl-curve25519 qrcode python-axolotl ];
       });
    buildInputs = [gajim_];
} ""

when trying to build it, I get the error message

running install tests
python test/runtests.py
process 19420: arguments to dbus_move_error() were incorrect, assertion 
"(dest) == NULL || !dbus_error_is_set ((dest))" failed in file 
dbus-errors.c line 282.
This is normally a bug in some application using the D-Bus library.
   D-Bus not built with -rdynamic so unable to print a backtrace
make: *** [Makefile:986: test] Aborted

/run/current-system/sw/bin/nix-shell: failed to build all dependencies

so I cannot really build anything with OMEMO support. I am really out of 
ideas now. How can this be done? Can somebody help, please?

It would btw be nice to have a gajim-omemo package, as many other 
distros do, since OMEMO is such an essential feature.
