c++ - Ogre3D 显示段错误

Question

我正在使用 Ogre3D 编写游戏，但遇到了问题。

当我启动程序时，它显示一个段错误:

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

(部分代码来自 Ogre Wiki)

资源.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

并且 - 当我在 plugins.cfg 中评论 Plugin=Plugin_CgProgramManager 时...程序可以运行，但我需要这个插件。 :)

请帮忙。
提前致谢。

Answer 1

1. 编译包含调试信息的程序(使用 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，您会得到一个堆栈跟踪。
4. 调查它是否似乎取决于您所做的事情(或未做的事情，例如缺少初始化)，或者它是否看起来像是 Ogre3D 本身的崩溃。
   1. 如果是前者，请修复它。
   2. 如果是后者，请报告。
