Hi,
your backtrace states that you are linking against Qt 4 or a mixture of 4/5. Please do the following steps:
Open cmake Set QT5_INSTALL_PATH to your Qt installation dir( e.g. .../Qt-5.5.1/5.5/gcc_64 ) Select all other Qt related entries in cmake and remove them. configure generate.
You should not see any other qt4 related entries after this. Then rebuild.

Ah, I see. I included the backtrace (using GDB) below.

Hi,
we don't support Qt 5.6 yet. There are some modules missing in 5.6 so we need to port things in order to work without these modules.
However, can you send a backtrace of the segfault? (Should be generated by OpenFlipper automatically) Maybe we can see what's happening.
Best, Jan Möbius

Hi,
I just cloned the OpenFlipper-Free repository (https://www.graphics.rwth-aachen.de:9000/OpenFlipper-Free/OpenFlipper-Free.g...) and compiled it successfully (64bit Linux). However, when I try to run OpenFlipper, I immediately get a Segmentation fault. Could this be due to the fact that I'm using Qt 5.6 (there was a warning about this when running cmake)? If there's any other information I could provide, please let me know.
Thanks, Pieter
