Segmentation fault $EMCDISPLAY -ini ......

hello,
The launch of emc2 I have a problem opening the window emc2. (see file attached).
In the ini file: axis with the interface it works (DISPLAY = axis), but with our specific interface (in qt4) does not work.
With an ini file in simulation mode (without hosmot2) we have no problem whatsoever with the interaction axis or our interface.

Our configuration:
Ubuntu 10.10
emc 2.4.5
rtai 3.8

If someone has an idea, thank you in advance.

thank you for the info.
I think I have found, I have trouble with the compilation of our interface and liaison with the library libnml.
Michel

Hello,
Thank you for your offer of assistance. We discuss a possible setting for a free license of all, some or not the project.
Probably we will present the project at the beginning of September.
best regards
Michel
