Could you provide your ~/.local/share/ember/ember.log file?

[emmanuel (emmanuel-tuloup)]

thanks for your answer

there the file, but this morning there wasn't this error again

perhaps a standby mode/wake up of the system has changed somethings ?

i've succeded in create a character and walk, but the terrain isn't there:
i can see trees, houses, grass, flowers, characters, but not the terrain (static meshes ?)

that was for the compiled ember on my system (v1.8)

for the donwloaded version, there is an error:

i give precision about that i've compiled the ogre 1.9 source from bitbucket some days ago directly, into another directory,
and develop a little application that use OgreBullet, load some meshes, create some bullet objets into the world, created a sun that revolve around my world and create shadows

and i've never met this problem with my driver r600

[emmanuel (emmanuel-tuloup)]

my sources there:
https://bitbucket.org/emmanuel1359/

[emmanuel (emmanuel-tuloup)]

well i've relaunched the compiled version 0.8, and the error reappears
there the log

[Erik Ogenvik (erik-ogenvik)]

This error is unfortunately caused by bad drivers. I.e. the low level drivers that supply the OpenGL functionality are broken, and will in some cases result in a crash. We've seen this before with Mesa-drivers on both AMD and Intel.

The only recommended solution is to try with other drivers. Perhaps the proprietary provided by AMD if possible, or other open source ones. I'm not that well verses with the AMD driver eco system to provide a better answer.

[Erik Ogenvik (erik-ogenvik)]

Marking this as confirmed, although it's not a bug in either Ember or Ogre (which is the 3d graphics library we use).

[emmanuel (emmanuel-tuloup)]

Hello again,

is there some doc to learn how the code source is organized ?
I would like to add the behaviour of natural life : animals and trees
from wich source file the ogre meshes are imported ?

i've read some source into:
hammer/work/source/worldforge/clients/ember/src/components/ogre/

the web site tell about "Plants grow and wither. Animals roam the world,
eating and getting eaten."
where is this code ?

i've intregrated bullet into my little ogre application, are you interested
into integrating bullet into worldforge ?
into cypheris or ember ? i'am a little bit lost about what module do what,
cypheris is the server and manage network communication, but where is a
character manager into it ?

Worldforge is made up of a lot of different components, so it's not always clear on where to start.

The wiki has a lot of useful content, but it's also a bit disorganized. But do check it out: http://wiki.worldforge.org/wiki/Main_Page

Here's a quick overview of the various Worldforge libs: http://wiki.worldforge.org/wiki/Ember_development#Worldforge_libraries

Regarding Ember and Cyphesis it's worth knowing that the server (Cyphesis) is authoritative in everything. So any behaviour or rule is always placed on the server.
The code for Plants for example is contained in Cyphesis, more specifically in the "ruleset" module.

We do have an ongoing project for integrating Bullet into the system, starting at Cyphesis. Do you have any example of the work you've done with Bullet?

[emmanuel (emmanuel-tuloup)]

ok, i'm going to read this as soon as i have some free time.

yes there my little application:
https://bitbucket.org/emmanuel1359/heightmapterrain/src

i've integrated bullet with an heightmapped terrain,
and tried to do the same thing with a TerrainVolume (i would like to dig
the terrain, to find some ore...)

I have confirmed this with Xubuntu 14.04.3 LTS on three different hardware platforms (eMachines, HP Proliant, and a more modern HP with quad processor and 8 GB RAM), so I think it needs addressing. As emmanuel is mentioning, many other applications are working fine with OpenGL (e.g. Blender). I would like to try any help diagnose and solve this bug, so am setting up a fresh system on the hardware that fails... more to come.

[Jonathan Deeds (jonathandeeds)]

The seg fault crash occurs when either of the following functions are called inside Ogre for the first time. The OpenGL documentation says the arguments are valid, although not sure why one is trying to unbind before anything has happened yet.

Function GLStateCacheManagerImp::initializeCache()

        glBindFramebuffer(GL_FRAMEBUFFER, 0);

        glBindRenderbuffer(GL_RENDERBUFFER, 0);

This crash happens even with Ogre's Wiki - Basic Tutorial 1. However if I rebuild Ogre with these two lines commented, the tutorial runs, and I get about 300 FPS.

Ember runs also up to the point of rendering a blank screen after the settings and login as admin. This might be due to some other misconfiguration on my part, but looks hopeful.

[Jonathan Deeds (jonathandeeds)]

Checking the Open GL documentation and my Open GL version on the test machine, I see that these functions are not supported until Open GL 3.0, but my test machine is running Open GL 2.1.

glxinfo gives OpenGL version string: 2.1 Mesa 10.5.9

I guess Ogre really should check the Open GL version level before trying to call functions that are not implemented.

My choices are probably two: 1) find an older version of Ogre that works with Ember (unlikely), or 2) try the proprietary drivers to see if it can raise the Open GL version to 3.0 or higher.

[Erik Ogenvik (erik-ogenvik)]

NIce find. You should really report this issue on the OGRE forum.

[Erik Ogenvik (erik-ogenvik)]

Regarding #15, this is a separate issue. Could you report this as a new bug?
It seems like the main issue is that if we can't access the sound card (for whatever reason, including there being no installed sound card) Ember crashes.
