Using CADFEKO on Ubuntu Machine
Hello,
I'm trying to install and use FEKO on a Ubuntu machine. I've successfully installed in and run ". initfeko" and I'm getting this error when I try to run "cadfeko":
_______________________________________________________________________________________________________
QCoreApplication::applicationDirPath: Please instantiate the QApplication object first
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: linuxfb, minimal, offscreen, vnc, webgl, xcb.
Aborted (core dumped)

Can anyone help?
Thanks!

Dear Spencer
The following information from the Altair Feko 2022 Installation Guide should be useful here:
Determining Missing Linux System Dependencies
If CADFEKO or POSTFEKO fails to start up with a message referring to “xcb”, the following commands can be run to determine if a system has missing dependencies:
ldd $FEKO_HOME/bin/platforms/libqxcb.so | grep "not found"
ldd $FEKO_HOME/bin/xcbglintegrations/libqxcb-glx-integration.so | grep "not found"
where $FEKO_HOME is set to the Feko installation path which contains the bin subdirectory.
Note: Ignore libQt* dependencies, since these are resolved by the application at startup.
Kind regards,
Johan H
