wb_view (workbench 2.0.0) crashes in ubuntu 24.04.1 #80
Comments

Can you run ldd on this library to see if any dependencies are missing:
ldd /home/baronlab/Software/workbench_2.0.0/libs_linux64/plugins/platforms/libqxcb.so
https://forum.qt.io/topic/93247/qt-qpa-plugin-could-not-load-the-qt-platform-plugin-xcb-in-even-though-it-was-found/152
It is suggested to install this package:
sudo apt install libxcb-cursor0

Hello.
I recenlty downloaded workbench 2.0.0 in a fresh install of Ubuntu 24.04.1.
wb_view crash in start up with the following error:
***@***.***:~$ wb_view
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".
Available platform plugins are: linuxfb, minimal, offscreen, xcb.
Reinstalling the application may fix this problem.
Aborted (core dumped)
I defined QT_DEBUG_PLUGINS=1 to see more details. The final paragraph before the crash is:
Got keys from plugin meta data ("xcb")
QFactoryLoader::QFactoryLoader() checking directory path "/home/baronlab/Software/workbench_2.0.0/exe_linux64/platforms" ...
loaded library "/home/baronlab/Software/workbench_2.0.0/libs_linux64/plugins/platforms/libqxcb.so"
QLibraryPrivate::loadPlugin failed on "/home/baronlab/Software/workbench_2.0.0/libs_linux64/plugins/platforms/libqxcb.so" : "Cannot load library /home/baronlab/Software/workbench_2.0.0/libs_linux64/plugins/platforms/libqxcb.so: (/lib/x86_64-linux-gnu/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var)"
This application failed to start because it could not find or load the Qt platform plugin "xcb"

Available platform plugins are: linuxfb, minimal, offscreen, xcb.
Reinstalling the application may fix this problem.

Any hints what can I try to make it work?
Note: wb_command seems to wok fine.
Thank you for the help (and the amazing software!).
Best,
Ricardo

ldd libqxcb.so output: I installed libxcb-cursor0 in the machine but still got the same crash. |
|
Just for sanity, you put the Another possibility is to install from neurodebian instead of the zip download: |
|
Yes, I'm configuring a new computer for the lab and I'm using Lmod modules system to handle software paths. An executable zip version is prefered to handle multiple versions etc. etc. Has any other user with ubuntu 24.04.1 experienced the same problem? |

Try running ldd on the libqxcb.so that is included with workbench. “ldd libqxcb.so” may have run on a library installed on your computer.
prompt> ldd /home/baronlab/Software/workbench_2.0.0/libs_linux64/plugins/platforms/libqxcb.so
At the bottom of your first email is a link failure:
"/home/baronlab/Software/workbench_2.0.0/libs_linux64/plugins/platforms/libqxcb.so" : "Cannot load library /home/baronlab/Software/workbench_2.0.0/libs_linux64/plugins/platforms/libqxcb.so: (/lib/x86_64-linux-gnu/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var)"
This might be related, it has the same undefined symbol:

Yes, bin_linux64 is in the $PATH. which wb_view works as expected.

Yeah I did run ldd to the library inside workbench folder (I'm sorry for the confusion) |
|
Also related https://github.com/helloSystem/LinuxRuntime/issues/11. I tried the solution of both posts (LD_PRELOAD=/usr/lib/libfreetype.so wb_view ) but not luck so far :/ |
|
Same issue here after updating to ubuntu 24, would be super grateful for any suggestions! :-) |
|
1. Try running mesagl_wb_view that is in the bin_linux64 directory. This version uses software graphics libraries but I expect the same error.
2. Did we run “ldd” on the executable to see if it has any library failures? In the “exe_linux64” directory, run “ldd wb_view”.
3. In “libs_linux64”, try removing libfreetype.so.6 and then run wb_view (should use versions of this library installed on your computer, if they exist). You might also try removing libftgl.so.2.
4. Build workbench from the source code.

Removing "libfreetype.so.6" in "libs_linux64" did the job! Thank you! |
|
Hello again. Yes, I did run "ldd" on the executable inside exe_linux64. Erasing libfreetype.so.6 in the exe_linux64 folder solved the issue. I think I manually installed libfreetype at some point so I am not sure if it is already preinstalled in the latest ubuntu. But it solved the issue! |
