Ogre3D显示段故障错误

Question

我正在用Ogre3D写一个游戏，我有一个问题。

当我启动程序时，它显示segfault错误：

我不知道为什么..。

代码：

#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

(代码部分来自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

和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

当我在plugins.cfg里评论Plugin=Plugin_CgProgramManager的时候...程序可以工作，但我需要这个插件。:)

请帮帮忙。

提前谢谢。

Answer 1

1. 使用包含的调试信息编译程序(对于GCC，这意味着确保将-g选项传递给编译器)。
2. 在调试器中运行它。
3. 当它崩溃时，如果它看起来依赖于您做过的(或没有做过的，例如缺少初始化)，或者看起来像是Ogre3D中的崩溃，那么您将获得堆栈a。如果是前者，则报告
4. 。如果是后者，则报告
