Fedora 26 ember crash on startup "Could not load gui"

[albiorix]

Hi. I've installed ember, cyphesis and dependencies from the packages supplied by the Fedora team.
The configuration screen comes up, I leave everything as-is, the program starts loading stuff and then fails.

Here are the messages -

I've looked in the ember.log file, and it fails immediately it tries to start CEGUI for the second time -

So there seems to be a problem with OgreDynLib to load the respective shared libraries:

1. RenderSystem_GL.so
2. RenderSystem_GL_d.so
3. Plugin_ParticleFX.so.
4. Plugin_ParticleFX_d.so
5. Plugin_CgProgramManager.so
6. Plugin_CgProgramManager_d.so
7. Plugin_OctreeSceneManager.so
8. Plugin_OctreeSceneManager_d.so

Do you have the development headers for Ogre installed? You should also check /usr/lib, /usr/lib64, /usr/local/lib and /usr/local/lib64 for the respective files.

OK...I've looked carefully through this stuff again, the system tries to load its plugins from various places (/usr/lib, /usr/local/lib, /usr/lib64, /usr/local/lib64, etc. It also varies the name from .so to _d.so until it either succeeds or runs out of options. The only one it has run out of options on is CgProgramManager, which makes sense because that seems to be some kind of NVidia thing and I don't have any NVidia hardware. I've dyked it out of the config file, and it no longer tries to load it.

The only real error now that I can see is -

Okay, so there seems to be a Lua problem in /builddir/build/BUILD/cegui-0.8.7/cegui/src/ScriptModules/Lua/Functor.cpp:222. Do you have the proper lua packages installed?

[erikogenvik]

The error seems to be that the Lua module "debug" isn't available in Fedora by default.
I'll patch the current source to check for it, but in the meantime you can disable that functionality by adding the following to your ~/.config/ember/ember.conf file.

[lua]
debug = false

[erikogenvik]

This issue is now also fixed in commit ca699b9
