[SOLVED] RTShadersSystem doesn't start up after upgrade

[paul424]

Ogre Version: : 1 13 6 5:
Operating System: :Linux Tumbleweed:
Render System: :OpenGL3+
I try to upgrade to the relatively new Ogre3d, which would have the CEGUI support -- that is 1 13 6 5 version.
I keep getting errors when loading materials which depend on RTSS like this :

Parsing script GoblinBed.material
Error: ScriptCompiler - reference to a non existing object in GoblinBed.material(2): RTShaderSystem.material
Error: ScriptCompiler - base object not found in GoblinBed.material(3): RTSS/NormalMapping_MultiPass

Also the CEGUI returns an error :

"An exception has occurred: CEGUI::RendererException in function 'void CEGUI::OgreRenderer::constructor_impl(Ogre::RenderTarget&)' (/home/tom/Downloads/cegui-0-8/cegui/src/RendererModules/Ogre/Renderer.cpp:802) : RT Shader System not available but trying to render using OpenGL 3.X+ Core.When GLSL shaders are necessary, the RT Shader System component of Ogre is required for rendering CEGUI."

I believe the RTShader are correctly set up in resources.cfg :

Code: Select all

allow using GL3Plus

still the main problem of RTSS being to late persist I get :

An exception has occurred: CEGUI::RendererException in function 'void CEGUI::OgreRenderer::constructor_impl(Ogre::RenderTarget&)' (/home/tom/Downloads/cegui-0-8/cegui/src/RendererModules/Ogre/Renderer.cpp:802) : RT Shader System not available but trying to render using OpenGL 3.X+ Core.When GLSL shaders are necessary, the RT Shader System component of Ogre is required for rendering CEGUI.

After close examination , the CEGUI is really created after RTSS. Seems the RTSS here doesn't start at all....

Uhh I downloaded the paroj version of CEGUI and now everything bells and whistles , I have a working 1 13 6 5 version of OGRE !!!!!!
