Help building shairport-sync

Hey guys

Love the project but waned to try to make a addon

Kodi includes airplay by default but shairport-sync allows for synced multi-room audio.

I have built it for OSMC which was really easy, but I dont want anything else than Libreelec running on my boxes at home

I just started messing around with the plugin buildsystem, but hit my first hurdle.

According to the readme there are some dependancies that need to be included:

The following libraries are required:

OpenSSL or PolarSSL
Avahi
ALSA
libdaemon
autoconf
automake
libtool
libpopt
libconfig

The error I'm getting is:

Quote

>>Including libpopt
checking for POPT... no
configure: error: Package requirements (popt) were not met:

No package 'popt' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

If I understand it correctly I would need to statically build popt/libpopt if I want the plugin to work on a vanilla libreelec install?

Can anyone confirm that and maybe even point me in the right direction to do so?

Thanks

Quote from chewitt

Popt is not currently built/used by anything else in the build-system so you will need to create a popt package and add this as a dependency to the shairport-sync package. We also use LibreSSL instead of OpenSSL, but that's probably a minor difference.

Thanks for the reply - I ended up building it on ubuntu and copying the binary + libs over

I needed to add the path to the systemd service file to make it work:

Environment=LD_LIBRARY_PATH=/lib:/storage/.kodi/addons/plugin.audio.shairport-sync/lib

Really hacky but works until I figure out the build process.

I saw that and I can run it from bash, but when systemd launches the library the path is not there

Instead of playing with it I just added the variable to the service file (maybe it´s not correct)

[Unit]
Description=ShairportSync AirTunes receiver
After=kodi.target


[Service]
Environment=LD_LIBRARY_PATH=/lib:/storage/.kodi/addons/service.shairport-sync/lib
ExecStart=/storage/.kodi/addons/service.shairport-sync/shairport-sync


[Install]
WantedBy=kodi.target

As I said it´s just a hacked together solution for now so I did not even make a .zip to install from, just copied the files over (to /storage/.config/systemd and /storage/kodi/addons) and enabled the service.

Maybe LE is doing something in the background when a addon is correctly packaged and installed via ZIP.. but I will cross that bridge when I can cross compile it with the LE build utilities

Is the best way to compile the libraries needed and package them with the addon (like my hack does now)?

I however would need to script the build so it would work on all platforms. I saw that the Chromium is doing something like that I maybe I could use that as a template?

The only problem I see is meeting the dependencies during build time
