Comment:
I've almost successfully packaged `jami-daemon` (see [this commit](https://github.com/chloris-pale-green/void-packages/commit/e2e1ef07781df3376d0ac3ad15485c36f569caa2)). The build documentation is quite abysmal. I've ripped off most of the build process from Arch. Dependencies compile successfully, the configure step is successful (except some complaining about `dbus`, which can be disabled, if needed), but the `jami-daemon` itself fails to compile. We don't have `libnatpmp` in the repos, if that's desired.

The compile error seems to be about class member naming:

```

And so on... Any suggestions? Is is sloppy code or does one of our libraries have different variable names in it than on another distro (`ch_layout` vs `channel_layout`)? We don't need to patch the source files to rename them, right? If that's the case, `sed` would probably do the job.
