I try to run my program as described in the used guide with the command
tcollect -b myfile.e
and I get the following error message:
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.

Error reading configuration file /usr/bin/gauss.cfg: Can't open configuration file
My operating system is Ubuntu 16.04 LTS.
I haven't found any forum entries or other documentation on the profiler except in the user guide.
I found a way to make it work. The problem was that I created a symbolic link to call tcollect from everywhere. This implied, however, that tcollect did not find files in /bin within my GAUSS directory.
Executing tcollect from its original directory does the trick.
In GAUSS for Linux version 18 and newer all binaries, including
tcollect, are launched through a shell script which maintains the correct path. So the symbolic link should work fine for newer versions.
