Segmentation fault on CentOs (Linux)
« on: April 19, 2011, 08:53:34 PM »

Currently I am unable to launch the gui on CentOS.  The version I have installed is 6.1.2.  Here is the output from gdb

Any ideas as to why it wont load?  Let me know if you need additional information.

Which release of CentOS is this?  We currently support up to CentOS 5.5

In addition to the compiled executable, we also ship the python source for the QubeGUI.  This is packaged into the qubeGUI .rpm, and will be located in /usr/local/pfx/qube/api/python/qb.

You will need the following dependencies installed, all of which should be available via yum:


You should then be able to run "python  /usr/local/pfx/qube/api/python/qb/"

Once you are able to run the interpreted version of the QubeGUI, you may re-compile a version appropriate to your local installation and distribute it to your users.

You will need pyinstaller, available at

To compile into an executable, run "python" in the api/python/qb/gui directory.
