I have compiled gazebo from source. When I try to lauch it, either as "gazebo" or as "gzclient", it crashes. Doesn't show any splash screen. The gzserver does not seem to crash.

Backtrace obtained through gdb :

Program received signal SIGSEGV, Segmentation fault.

Any suggestions on how I can move forward with this installation ? BTW I have performed "make tests" and will update this when any results are available.

I am ready to provide more information if you tell me what would be useful.

What branch of Gazebo are you compiling? Which version of Qt do you have installed and which version are you linking against? It looks like Qt is not finding some headers.

the branch is "default", I have both Qt4 and Qt5 installed. I believe I am linking against Qt5 (according to some Makefiles I found in the build directory) but actually I'm not too sure. How can I check that ?

@chapulina thanks to your helpful hint, I can now launch gzclient. There was some mix-up between some qt4 and qt5 libraries, in particular owing to the fact that, apparently required by the Gazebo GUI, is provided solely by a Qt4 package (I am talking about Debian here). I had to resort to a trick, namely create a symbolic link of that name pointing to its nearest equivalent on Qt5,, and that's a very hackish solution. Still il solved my current problem.
