failure, see the Visual C++ documentation on asserts.

That's what I got when I try to execute my Ogre application. Source is a total copy of Ogre Tutorial Framework. I found ridiculously much exceptions from Ogre.log. It seems like that all of the errors came from OgreGpuProgramParams.cpp and OgreResourceGroupManager.cpp. Some of the first ones coming next. I couldn't paste em all, because there's about 1000 lines of that crap.

Notice, that those errors came only when using OpenGL or D3D9 rendersystems. When using D3D11, runtime error is different:

OGRE EXCEPTION(3:RenderingAPIException): Attemped to render to a D3D11 device without both vertex and fragment shaders there is no fixed pipeline in d3d11 - use the RTSS or write custom shaders. in D3D11RenderSystem::_render at ..........\RenderSystems\Direct3D11\src\OgreD3D11RenderSystem.cpp (line 2496)

I can paste even more info is it's necessary. Does anybody know a solution?

This error usually appears if you are mixing release and debug builds. Most likely your application was built in release mode while you are trying to use debug build DLLs in this case of Ogre.

You can use a tool such as Dependency Walker to check what DLLs exactly are loaded during your application's run.

Another reason could that your Ogre DLLs where generated by a different IDE/compiler version than your actual application is. This will often make them binary-incompatible resulting in crashes. This can happen due to different versions of the standard library and associated dynamic allocation issues. The same is possible if you build the Ogre libraries as 'static', but use dynamic dependencies (e.g. OIS, plugins, etc.).

Regarding the errors in the log: You seem to be missing some media files (e. g. shaders) which cause those log entries.

Regarding D3D11: With that version Microsoft removed the FFP (fixed-function pipeline). So everything is now shader based which means that you either have to write/provide these on your own or use Ogre's integrated shader generator (RTTS).
