Cool VL Viewer forum

Hello Henri.

Since the last few days —ever since I started meddling with my system in order to build some 32-bit prerequisite libraries for gstreamer— I can't start coolvlviewer. Today I downloaded the installer again, ran it with no changes whatsoever and I'm enclosing logfiles.

LL Viewer, Firestorm and Dolphin (all 32-bit viewers) start normally. Singularity (natively 64-bit) of course starts normally.

CoolVLViewer starts and works normally, but only if the offending library (/usr/lib32/libspeexdsp.so) is missing. So, I figure it's a coolvlviewer-specific issue. Could you please look at it?

Thanks in advance.

The stacktrace says it all:

This is a crash (caught by the viewer error handler) in libspeexdsp.so.

This is *not* a viewer bug, but a library bug issue on your particular Linux distribution.

The reason why you don't see it happening in other viewers if probably because they are using OpenAL (or FmodEx) instead of FMOD which the CoolVLViewer uses by default and OpenAL probably doesn't trigger the loading of that faulty library. You can update to a fixed library or switch to OpenAL by editing the first lines of the cool_vl_viewer wrapper script, like so:

Yes, indeed. I figured it out on my own. Apparently the distro binary was corrupted. I rebuilt it and everything works fine now. Sorry to have bothered you.
