Hmm, I must have forgotten to test Rygel once I started focusing on GUPnP. Otherwise, I do not understand how could I have missed this.

The issue with docs is that they still depend on old GUPnP:

error: Package `gupnp-1.0' not found in specified Vala API directories or GObject-Introspection GIR directories
error: Package `gupnp-1.0' not found in specified Vala API directories or GObject-Introspection GIR directories

Can you add the following patch https://gitlab.gnome.org/GNOME/rygel/issues/132#note_457444

and docbook_xsl and docbook_xml_dtd_43?

I've done those exact things manually and things at like
result-devdoc/share/gtk-doc/html/librygel-core were empty directories...

Saw all the same warnings too so I thought it wasn't worth it.

I might be doing something wrong but I still get the same build failure with your branch.

I will take a look on complete fix later. This should be good to go for now.

Though maybe we need to link the etc file in rygel module.

Here is my failed build output: https://hastebin.com/inomojigis.sql

EDIT: actually never mind, I was also building my main channel version as well. Oops...

I've runtime tested and it does load /etc/rygel.conf.

The command you used to build was incorrect

nix-build '<nixpkgs>' -A gnome3.rygel ~/repos/nixpkgs

should be

nix-build ~/repos/nixpkgs -A gnome3.rygel

By doing <nixpkgs> you just built this from nixpkgs of your current system.

The command you used to build was incorrect

Thanks for the pointer! That did the trick, and it's now building correctly.

I'm new to NixOS and sometimes these things aren't obvious :).

I understand. Thanks for testing ❇️
