vaapivideo Fehler beim start: undefined symbol: __epoll_pwait2_time64

Hallo,

ich wollte mal vaapivideo auf meinem Laptop testen es kommt aber bei Start von vdr

./vdr -Pskincurses -P'vaapivideo -d /dev/dri/card1':

dieser Fehler:

vdr: /usr/lib/libsystemd.so.0: undefined symbol: __epoll_pwait2_time64

zum Bau des vdr bin ich so vorgegenagen:

Code

git clone https://github.com/dnehring7/vdr-plugin-vaapivideo.git
cd vdr-plugin-vaapivideo/
cp ../../Downloads/vdr-29200d0.tar.gz .
tar xzvf vdr-29200d0.tar.gz 
mv vdr-29200d0 vdr
make
cd vdr
cp Make.config.template Make.config
Make.config
make -j 6 ONEDIR=1 LCLBLD=1

das ist unter Manjaro Linux.

Wenn ich vdr starte kommt obiger Fehler. Kompilieren läuft alles schön durch.

I also see this on my Debian testing systems (rolling release) after recent upgrades.

As far as I understood it's a mismatch between libc and the systemd library.

Can you try a full system upgrade?

As a dirty workaround I rolled back libsystemd as in example below to 'libsystemd.so.0.43.0' You'll need to repeat this after each reboot and after 'ldconfig' ran

Code

lrwxrwxrwx 1 root root      15 27 jun 20:50 libsystemd.so -> libsystemd.so.0
lrwxrwxrwx 1 root root      20 13 jul 08:30 libsystemd.so.0 -> libsystemd.so.0.43.0
-rw-r--r-- 1 root root 1152376  1 jun 17:43 libsystemd.so.0.43.0
-rw-r--r-- 1 root root 1205560 27 jun 20:50 libsystemd.so.0.44.0

I guess we need to either wait for this to be solved upstream or file a bug report to the distribution maintainers

Hi,

thank you very much for anwering. No I know it's not only on my system.

It's the same after full upgrade, there's just:

Code

lrwxrwxrwx 1 root root      15 27. Jun 17:12 libsystemd.so -> libsystemd.so.0
lrwxrwxrwx 1 root root      20 27. Jun 17:12 libsystemd.so.0 -> libsystemd.so.0.44.0
-rwxr-xr-x 1 root root 1332616 27. Jun 17:12 libsystemd.so.0.44.0

I will test with the distributions mentioned for the plugin.

Best
