cannot start vlc with skins2 (segmentation fault)

[obelix]

Hi,
i have compiled vlc with all depending libraries from scratch for GoboLinux. Everything seems to work fine but skins2. Everytime i want to start svlc it crashes with segmentation fault. But there is no further hint, which tells me what is probably wrong.

svlc -vvvv
VLC media player 0.8.2 Janus

zsh: segmentation fault svlc -vvvv

Can somebody help me, please?
Do i need some special libraries for the skins2 interface? (GTK?)

Thanks

could you try deleting ~/.vlc (just to be sure)

then i'll get the following:

[obelix]

i have found the problem. I have to compile vlc with -lm because the ping library is using the math library.

thanks

[deboutv]

I have exactly the same problem but compiling with -lm does not solve my issue.

Can somebody help me, please?

[nemesi]

Can you explain me this? What do you mean with "-lm"?

./configure -lm or what?

Have a nice day

[ipkiss]

Compiling with -lm actually means linking with the math library. It cannot be done with a configure switch, you need to edit the vlc-config file after configuring, and before running make. But i really doubt that it would change anything...

Something much more useful would be to have a backtrace of the crash.
On Unix, you can do the following:
- compile vlc in debug mode if possible
- run 'ulimit -c unlimited' to make sure vlc generates a core file when it crashes
- start vlc, and make it crash --> this generates a core file
- run 'gdb vlc core' where vlc is the path to the vlc executable, and core is the path to the generated core file
- type 'bt' in gdb
- post the results here

Hello,

So the crash is in the ffmpeg library.
You should try compiling with more recent versions of ffmpeg (or older?)...

[deboutv]

Thanks for your help, now it runs.

But, I have another question: I am installing VLC for the FreePlayer tool ( http://adsl.free.fr/tv/freeplayer/) and I need the options "--sout-ts-pid-*". I have configured VLC with "./configure --prefix=/usr --enable-wxwindows --enable-debug --enable-release"
but the options "--sout-ts-pid-video" is unknown.
Can you help me?

Thanks

[deboutv]

I have found the solution: I need the library libdvbpsi.

Thanks
