Ogre3D shows segfault error - c++

Question

I'm writing a game using Ogre3D and I have a problem.
When I starting program, it shows an segfault error:
*-*-* OGRE Initialising
*-*-* Version 1.7.2 (Cthugha)
Creating resource group Essential
Added resource location '../media/packs/SdkTrays.zip' of type 'Zip' to resource group 'Essential'
Added resource location '../media' of type 'FileSystem' to resource group 'General'
Added resource location '../media/materials/scripts' of type 'FileSystem' to resource group 'General'
Added resource location '../media/materials/textures' of type 'FileSystem' to resource group 'General'
Added resource location '../media/models' of type 'FileSystem' to resource group 'General'
Naruszenie ochrony pamięci [This means segfault]
And i don't know, why...
Code:
#define OGRE_CHANGE1 ((1 << 16) | (1 << 8))
#include "Ogre.h"
#include "ExampleApplication.h"
#if OGRE_PLATFORM == OGRE_PLATFORM_WIN32
#define WIN32_LEAN_AND_MEAN
#include "windows.h"
#else
#include <iostream>
#endif
class MyApp : public ExampleApplication
{
protected:
public:
MyApp()
{
}
~MyApp()
{
}
protected:
void createScene(void)
{
}
};
#ifdef __cplusplus
extern "C" {
#endif
#if OGRE_PLATFORM == OGRE_PLATFORM_WIN32
INT WINAPI WinMain( HINSTANCE hInst, HINSTANCE, LPSTR strCmdLine, INT )
#else
int main(int argc, char **argv)
#endif
{
MyApp App;
try
{
App.go();
return 0;
}
catch (Ogre::Exception& e)
{
#if OGRE_PLATFORM == OGRE_PLATFORM_WIN32
MessageBox( NULL, e.getFullDescription().c_str(), "Exception!",
MB_OK | MB_ICONERROR | MB_TASKMODAL);
#else
std::cerr <<"Exception:\n";
std::cerr <<e.getFullDescription().c_str() <<"\n";
#endif
return 1;
}
}
#ifdef __cplusplus
}
#endif
(Code partly from Ogre Wiki)
resources.cfg:
# Resources required by the sample browser and most samples.
[Essential]
Zip=../media/packs/SdkTrays.zip
# Resource locations to be added to the default path
[General]
FileSystem=../media
FileSystem=../media/materials/scripts
FileSystem=../media/materials/textures
FileSystem=../media/models
and plugins.cfg:
# Defines plugins to load
# Define plugin folder
PluginFolder=/usr/lib/OGRE
# Define plugins
# Plugin=RenderSystem_Direct3D9
# Plugin=RenderSystem_Direct3D10
# Plugin=RenderSystem_Direct3D11
Plugin=RenderSystem_GL
# Plugin=RenderSystem_GLES
Plugin=Plugin_ParticleFX
Plugin=Plugin_BSPSceneManager
Plugin=Plugin_CgProgramManager
Plugin=Plugin_PCZSceneManager
Plugin=Plugin_OctreeZone
Plugin=Plugin_OctreeSceneManager
And - when I comment Plugin=Plugin_CgProgramManager in plugins.cfg... Program works, but I need this plugin. :)
Please help.Thanks in advance.

Answer 1

Compile the program with debugging information included (with GCC, this means make sure the -g option is passed to the compiler).
Run it in a debugger.
When it crashes, you'll get a stack trace.
Investigate if it seems to depend on something you did (or not did, such as a missing initialization), or if it looks like a crash in Ogre3D proper.
If the former, fix it.
If the latter, report it.
