For some reason, the PMS start script isn’t looking for in the Plex install lib folder.

I added this to the plex.sh script in the start section:

export LD_LIBRARY_PATH=${QPKG_DIR}/lib:$LD_LIBRARY_PATH

ChuckPa · November 23, 2020, 6:52pm

It’s not looking in the ./lib directory anymore because RPATH is set.

I am running on 4.4.3.1439 cannot replicate the failure.

[/share/CACHEDEV3_DATA/.qpkg/PlexMediaServer] # ./plex.sh stop
Stopping Plex Media Server...
[/share/CACHEDEV3_DATA/.qpkg/PlexMediaServer] # ./plex.sh start
Starting Plex Media Server...
[/share/CACHEDEV3_DATA/.qpkg/PlexMediaServer] #

We need to investigate this further and determine where the deficiency is.

jacobp · November 23, 2020, 6:55pm

@ChuckPa - let me know what I can look at to provide some more info on 4.5.1.1480.

My LD_LIBRARY_PATH looks like this - is it different than yours?

LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib:/opt/lib:/share/CACHEDEV1_DATA/.qpkg/QGit/lib:

ChuckPa · November 23, 2020, 7:46pm

Oh, that is NOT expected

What do you have installed?

jacobp · November 23, 2020, 7:48pm

What do you mean? My LD_LIBRARY_PATH?

jacobp · November 23, 2020, 7:55pm

@ChuckPa - doh! Sorry for troubling you on this one! Turns out some years ago I was manually setting LD_LIBRARY_PATH in /opt/etc/profile - in order to use an updated git.

removing that and everything looks correct in ldd and Plex starts and stops correctly.

Thanks for the quick response and pointing me in the right direction!

Jake

ChuckPa · November 23, 2020, 8:03pm

Jake,
Thank you for tracking that down.

HOWEVER —

Would you consider:

Put it back to how it was
Add the following change to your existing plex.sh

Down where the GPU card detection is performed & right before PMS is launched.

    # Append GPU Library path to LD_LIBRARY_PATH
    if [ "$GPU_LD_PATH" != "" ]; then
      export LD_LIBRARY_PATH=${GPU_LD_PATH}
    else
      unset LD_LIBRARY_PATH
    fi

This action clears LD_LIBRARY_PATH
It allows you to keep your system as it is.

I might need tweak it further but the general idea is to clear it and keep PMS atomic from the rest of the system.

Hi Chuck,

Yes this with the unset works just fine with my customized LD_LIBRARY_PATH - I don’t have an external GPU, so I can’t check the GPU_LD_PATH piece.

Thanks again!
Jake

Jake,
Thank you.

I was hoping you’d be able to confirm this works as expected.

I’ll see it gets included ASAP.

I also validated this with a couple of echo statements before and after the set/unset:

    echo "LD_LIBRARY_PATH => " $LD_LIBRARY_PATH
    # Append GPU Library path to LD_LIBRARY_PATH
    if [ "$GPU_LD_PATH" != "" ]; then
      export  LD_LIBRARY_PATH=${GPU_LD_PATH}
    else
      unset LD_LIBRARY_PATH
    fi
    echo "LD_LIBRARY_PATH => " $LD_LIBRARY_PATH

and which when execute:

[admin@qnap PlexMediaServer]# ./plex.sh start
Starting Plex Media Server...
LD_LIBRARY_PATH =>  /lib:/usr/lib:/usr/local/lib:/opt/lib:/share/CACHEDEV1_DATA/.qpkg/QGit/lib:
LD_LIBRARY_PATH =>
[admin@qnap PlexMediaServer]#

Thank you VERY much for helping out.

I’ve made the changes in packaging and am testing them now
