Segmentation Fault on Linux at startup (VLC 0.8.4.a and 0.8.

[Didier Spaier]

Hello,

I am using a Slackware 10.2 distro.

I could configure and make VLC wih both 0.8.4a and 0.8.5-svn (downoaded CVS tree this morning) versions but at startup in both cases I get this or that :

VLC media player 0.8.5-svn Janus
Erreur de segmentation

VLC media player 0.8.4a Janus
Erreur de segmentation

For information, my configure command was in both cases :

Code: Select all

./configure --prefix=/usr --enable-livedotcom --enable-dvdread --enable-cdda --enable-faad --enable-twolame --enable-flac --enable-theora --enable-caca --enable-skins2 --enable-ncurses --with-gnu-ld --with-livedotcom-tree=/usr/lib/live --with-ffmpeg-tree=/home/logiciels/ffmpeg --with-ffmpeg-mp3lame --with-ffmpeg-faac

Any idea ?

Try running 'vlc --reset-plugins-cache --reset-config'. Do you still get the crash?

Yes, in boh cases (after a few seconds first time I try it).

Thanks anyway

then add --enable-debug to your config line

and then install gdb and run
gdb vlc
run
wait for the crash
bt

and post the output of bt

I've installed wxGTK-2.6.2. Should I try an other one, or configuring it an other way ?

FYI I've installed Freerock Gnome too though I don't use it much.

Thanks,

Maybe there is a problem with --enable-unicode in xwWidgets

I tried a package from http://www.develia.org compiled without this configure's option and now VLC works -- though french accents are not displayed properly on the GUI

I have the same error on the Debian Linux on PowerPC 7447 Pegasos platform. I download the snapshot version 20060310.

PS, on my platform, there is no UTF-8 locale support, is it the causing?

[xtophe]

Orient:
The problem seems different.
Yours is more like a corrupt cache plugin. Delete ~/.vlc/cache

Or some older plugins remaining on the system, maybe

I have tried to rm -rf ~/.vlc. But the problem is still there. If you suspect there are some older plugins in the system, I should how to check this issue?

Thanks.

Maybe there is a problem with --enable-unicode in xwWidgets

Exactly the same symptom since I compiled wxWidgets with the -enable-unicode option.
I'd like to have the french accents in th gui.

I keep getting seg faults on the Ubuntu version but my GFs Deb testing with Marrilat sources works fine... this leads me to think sinve Christian is French he has solved this problem! I mean its seriously beautiful but when I did the apt-get it had huge deps and rebuilt all the language support files .. which for complex reasons includes quite a few languages!

I might eMail him and find out what exactly he did

[xtophe]

Hi,
The official ubuntu package is not so good.
You should try the one on http://nightlies.videolan.org

Thanks ... now looks great ... the utf stuff is all working too so French accents are working.
Now I need to work out how to record

Now, works fine with wxGTK 2.6.3.

I compiled vlc simply like this :

./configure --prefix=/usr --with-ffmpeg-tree=./ffmpeg-21826-7407/

It worked before with wxWidgets 2.6 but now I have installed wxWidgets 2.8. I have also change a thing in my /etc/profile : export LANG=fr_FR@euro before it was utf8

I've compiled wxWidgets 2.8 like this :

../configure --prefix=/usr --with-gtk --with-gnomeprint --with-opengl --enable-debug --enable-geometry --enable-graphics_ctx --enable-sound --with-sdl --enable-mediactrl --enable-display --disable-debugreport

other package installed on my LFS system : gtk+-2.10.1

Someone can help me please ?
Thank you.

[Jean-Baptiste Kempf]

Did you VLC patch for wx-2.8 ?

[cowmet]

Yes I did it by this command :

sed -i "s@SetStyle@SetWindowStyle@g" modules/gui/wxwidgets/dialogs.cpp

without it, it's impossible to compile vlc.
