[SOLVED] Zoom & Qt5 stuff

business_kid · 10-19-2020, 10:29 AM

Code:

bash-5.0$ /opt/zoom/zoom
zoom started.
Client: Breakpad is using Single Client Mode! client fd = -1
/opt/zoom/zoom: symbol lookup error: /opt/zoom/imageformats/libqsvg.so: undefined symbol: _ZdlPvm, version Qt_5
bash-5.0$ /opt/zoom/zoom.sh #This is their debug mode!
=============================================================================================
This is debug mode of zoom client. Once crash, zoom will generate core dump under this mode.
=============================================================================================
The current core dump file is "core".
Do you want to modify the default core dump file name?

And it starts up with no error :-o

Could this be my local Qt-5.15.1 interfering with zoom's older Qt? Or should I be doing something about the picture format

might be: you can check that removing the bundled Qt5 stuff from the zoom tarball, like described here

I'm running Zoom 5.3.472687.1012 on -current (from the SBo SlackBuild, but version bumped), not seeing any errors with qt5-5.15.1-x86_64-2 installed.

I just upgraded to 5.3.472687.1012, all is working well. I use my own SlackBuild but the only real differences are I use the zoom_x86_64.rpm as my source and install to /usr/lib64/zoom-client.

Interesting. I have the unzipped tar (Zoom 5.3.472687.1012) in /opt, & qt5-5.15.1-x86_64-1 from Alien Bob. The -1 & -2 are Slackware in-house things afaict, and not a package version.I also have a recently decent qt5-webkit - 5.212 or somesuch.

The only other thing that strikes me is that the zoom.sh alters the LD_LIBRARY_PATH, to /opt/zoom

Code:

#From /opt/zoom/zoom.sh

#LD_LIBRARY_PATH=$dirname/Qt/lib
LD_LIBRARY_PATH=$dirname
export LD_LIBRARY_PATH
echo $LD_LIBRARY_PATH
ulimit -c unlimited
$dirname/$appname "$@"

So the difference is that in running the zoom binary, the system has the run of my various libraries, but in zoom.sh it doesn't

EDIT: Well, another idea bites the dust. To test the LD_LIBRARY_PATH idea I hacked the script, set "LD_LIBRARY_PATH=$dirname" to "LD_LIBRARY_PATH=LD_LIBRARY_PATH:$dirname". And still, /opt/zoom/zoom.sh starts, but /opt/zoom/zoom pukes

Never had any problems with interference between Slackware's qt5 (right now qt5-5.15.1-x86_64-2) and the qt stuff that's part of zoom and resides in /opt/zoom-linux (right now qt5-5.9.9).

You write that you have the unzipped zoom tar in /opt, so apparently you haven't built and installed a SBo package. Maybe worth a try, since that solution works for me, and apparently for christretusn and drgibbon as well.

EDIT the -1 and -2 (et cetera) do indeed signify package versions, and sometimes that can be of great importance. From the Slackware changelog:

Quote:

Wed Oct 14 03:52:13 UTC 2020
l/qt5-5.15.1-x86_64-2.txz: Rebuilt.
Recompiled against llvm-11.0.0.

Which is why reading the changelog is important for -current users.

Yeah the number at the end is just the build number, but compile options could have changed or whatever.

The normal way to start it is with the 'ZoomLauncher' binary. For what it's worth, if i run the 'zoom' binary I also get:

Code:

zoom started.
Client: Breakpad is using Single Client Mode! client fd = -1
./zoom: symbol lookup error: /opt/zoom-linux/imageformats/libqsvg.so: undefined symbol: _ZdlPvm, version Qt_5

but no problems with ZoomLauncher.

business_kid · 10-20-2020, 10:29 AM

Yeah, you're right. Just lazy, I guess. I'll set about it. I just altered the entry in startup to zoom.sh, but that's the lazy way.

drgibbon · 10-20-2020, 10:52 AM

Hm, well ZoomLauncher is the usual way to start it from what I can see (e.g., SlackBuild on SBo will give you a desktop entry pointing to ZoomLauncher right from the start).

chrisretusn · 10-20-2020, 12:06 PM

I get no errors when launching zoom.

business_kid · 10-25-2020, 02:47 PM

Marked solved because ZoomLauncher works here too. It used barf on the 1st version, but they obviously fixed that.
