compiling_on_linux [Debian Squeeze Not Ubuntu]

[bistro2000]

Hi there,

The very first step at:

http://www.mixxx.org/wiki/doku.php/compiling_on_linux

doesn't work for my fresh Debian Squeeze:

Code: Select all

root@upc:~/mixxx/mixxx-1.10.0-beta1# apt-get build-dep mixxx
Reading package lists... Done

and then I run into a segmentation fault:

Most of the instructions seem very Ubuntu...
Has anyone been successful on Debian Squeeze ?

cheers

doesn't work for my fresh Debian Squeeze:

Odd since I believe there is a mixxx package in squeeze. You can just install each individual build dependency, that's all that that build-dep does. Based on your next queston it looks like you figured this out fine.

Xlib: extension "GLX" missing on display ":1.0".

Segmentation fault

Does glxgears work?

Could you please get a backtrace for that crash? http://www.mixxx.org/wiki/doku.php/creating_backtraces

[bistro2000]

Trying to fix the above, I fiddled shared libraries to a point where Squeeze no longer functioned, so I jettisoned it and installed Maverick. At first glance things seem to work... even Shuffle! But this server is to be headless... used only for broadcasting, NOT playback via soundcard. So I was hoping xrdp, xming, freenx, vnc or some sort of remote access solution would work. Alas, heavy duty glx, and stress from Jack... Although somewhat slow, I got your glxgears test to work with xming, but executing mixxx runs into another Segmentation fault after whole lot of complaints about Jack...

Code: Select all

8 frames in 5.5 seconds =  1.451 FPS

I can get this working on Windows together with rdp or LogMeIn but would've prefered a linux solution.

[rryan]

To give you a hint of how to fix this, could you get a backtrace? See the link I posted above.

[bistro2000]

If I follow the steps in the backtrace, the recurring Jack errors I mentioned before take a lot longer to cause the segmentation fault.

Is this output useful then?
I mean, it doesn't happen when Mixxx's screen output is local,
only when I start Mixxx via xming, xrdp, vnc and such like.
I'm afraid I don't know how Jack ties in with remote X windowing.

That's not the whole back-trace. Type set height 0 at the gdb prompt, then run Mixxx in it and collect all of the output.
