RTabMap launch error

[brunoeducsantos]

Hey,
I have a segmentation error launching  RtabMap GUI:

Error 4  in libQt5Widgets.so.5.5.1


OS: Ubuntu 16.04


Can you help?

Best,

Bruno

Hi,

Is the crash happen often? You could try starting rtabmap with gdb, then do "bt" (backtrace) when it crashes to have last functions called.

$ gdb rtabmap
$ run
... (use until crash)
$ bt

Copy paste bt log here.

Cheers,
Mathieu
