Using the Ubuntu 10.10 beta and installing MRT as follows:
sudo apt-get install mrpt-apps libmrpt-dev
I'm getting a crash when calibrating a camera using camera-calib. The parameters I'm entering are 6x9 pattern with 24mm squares. The video displays as usual, but it looks as if as soon as the pattern is detected the program crashes.
*FATAL*: Signal SIGSEGV caught!
Aborted (core dumped)
I did have this working previously, but on the 10.04 version of Ubuntu.
I hope this came just in time! :-)

My program was working in Ubuntu 10.04. Then I moved to Ubuntu 12.04 and it give me this runtime error:
*FATAL*: Signal SIGSEGV caught!
Aborted (core dumped)
I have installed the latest versions of MRPT packages. It would be great if you can help me to solve this
I had a similar problem running the RawLogViewer application.
After debugging on gdb i found out that the it was a seg. fault ocurred in libGL.so by fglrx.
So it turned out that it was a driver problem.
If you are using an ATI graphic card like me, maybe you need to remove the proprietary drivers and replace them with their open source equivalents.
That worked out for me, i replaced the correct drivers, re-installed mrpt-apps and restarted my computer.
If it still doesn't work at least try
$ gdb --args camera-calib
...
(gdb) run
