[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Different, but not better. vdr simply ends without doing anything.

since there is no coredump, i tried a strace with follow threads. I
uploaded the strace-output to

http://steckrue.be/vdr_debug.tbz

Just 4 Info, syslog says nothing:

Mar 19 15:35:46 localhost vdr: [3844] deleting plugin: graphlcd

everything works wonderfull, if using vdr-1.3.43 ..

Friedhelm.
