gazebo-9 gui doesn't launch
Hi,
I recently un-installed my copy of gazebo 7 that came with my installation of ros kinetic (desktop full) on my Ubuntu 16.04 system. It was crashing on launch and I attributed that to this issue based on Sharvashish Das's comment (I could have been totally wrong but I didn't really document my error tracking process.) I knew I needed to upgrade to gazebo 9 at some point anyway (project reasons) so I decided to install it from source based on the tutorial here. I also installed the dependent libraries from source as the tutorial suggested. I made sure that ros was not sourced during this whole process as the tutorial suggests.
Everything built and was installed in my usr/local/ directory. However, when I tried to launch gazebo it did nothing.
I tried to run the executable directly from usr/local/bin and still nothing
It seems that I can launch the gzserver executable. Here is the verbose output:
But I get a Segmentation fault (core dumped) output from the gzclient:
I read somewhere that this error could be fixed by installing the latest proprietary Nvidia drivers. I have a Nvidia GTX-970 graphics card, and found that the latest driver was the nvidia-390.25. I installed it, and made sure it was running:
but I'm still getting the same results. I'm not really sure what to do next. Try un-installing and re-installing? Un-install ros and gazebo and re-install gazebo-9 first? Is there something obvious I'm missing and I can avoid that all together?
As a side note. The install from source tutorial has you download and build everything from the /tmp directory, and then says to do sudo make uninstall from the build directory if you want to un-install. In my case, those directories got wiped when I had to reboot for the graphics drivers to update. I made local copies of these directories before I rebooted, but I'm still confused as to why they would have you do all this in the /tmp folder in the first place? I'm still somewhat new to Linux and don't do much building from source, so maybe that's a newbie question.
Good point about the `/tmp` dir, it would be great if you could send a change to gazbeo_tutorials: https://bitbucket.org/osrf/gazebo_tutorials/

@chapulina I added an issue https://bitbucket.org/osrf/gazebo_tutorials/issues/86/from-source-ubuntu-and-mac-tutorial-build
Thank you!
Hi, did you manage to solve the problem? I am facing exactly the same one. It seems when running the gzclient in gdb mode, the segmentation fault comes from Qt4: Program received signal SIGSEGV, Segmentation fault. 0x00007fffe8d795a4 in ?? () from /usr/lib/x86_64-linux-gnu/libQtGui.so.4
No, I never did get it working and just reverted back to gazebo-7 for the time being. I'm working on a different machine now and probably won't try gazebo-9 until my whole lab migrates away from ros-kinetic. This is a total shot in the dark, but do you have the right version of libqtgui? Might be related to this issue: https://bitbucket.org/osrf/gazebo/issues/2215/gazebo-9-link-with-wrong-qt
