Hi HifiBerry Folks,

Thanks for the awesome piece of hard- and software that is HifiBerry!

With my Raspberry Pi 3 I am going for a mpd satellite setup where my NFS Server runs mpd and stores the database. The raspberry pi shall mount the NFS Directory and use the proxy-plugin for the database.

Unfortunately mpd is compiled without nfs support and refuses to start when configured for nfs storage:

music_directory "nfs://fileserver.local/srv/mp3"

database {
    plugin "proxy"
    host "fileserver.local"
}

# mpd --version
Music Player Daemon 0.21.21 (0.21.21)

 ...

Database plugins:
 simple proxy upnp

Storage plugins:
 local smbclient udisks curl

I see you have disabled NFS Support in the file hifiberry-mpd.mk:

HIFIBERRY_MPD_CONF_OPTS += -Dnfs=disabled

What steps are needed to re-enable NFS Support?

Thanks,
Juo

  This would require building a new mpd with different configuration options. I would rather recommend to use SMB instead of NFS.

  Let me see if we can include it in the next release. Doesn't seem to be too much work.

  You can try this experimental build (release coming soon):

  Thanks for the build!

  I tried it myself but It returned errors on building mpd - nfslibs are missing. Enabling the nfs-utils package didn't help.

  CMake binary for MachineChoice.HOST is not cached
  CMake binary missing from cross or native file, or env var undefined.
  Found CMake: NO
  No CMake binary for machine MachineChoice.HOST not found. Giving up.
  Run-time dependency libnfs found: NO (tried pkgconfig)
  
  src/lib/nfs/meson.build:1:0: ERROR: Dependency "libnfs" not found, tried pkgconfig

  How did you enable nfslibs in buildroot? Thanks,
  Juo

  Just run "config"
  
  Our new mpd package has libnfs selected automatically

  Can I find the new mpd package config in the development branch?

  What do you think would be the best interface for mpd on hifiberry?

  The best is the one that will come at some point in the future ;-) Stay tuned...
  ympd is included. That's not the best in the worl, but it's working.

  It seems that current DLNA support is based on gstreamer, and wonder whether there's any special reason for adopting it instead of upmpdcli ? I ask this because I personally believe mpd sounds better than any other streaming implementations out there.

  Well, yes my personal view but just got curious !

  No specific reason, that was just the first we found. If you want to contribute another implementation, we'll look into it.
