Question

我尝试编译以下代码（来自Ogre3d初学者指南，由Felix Kerger出版）

#include "Ogre\ExampleApplication.h"    

class Example1 : public ExampleApplication
{
public:
void createScene()
{Ogre::Entity* ent =
mSceneMgr->createEntity("MyEntity","Sinbad.mesh");
mSceneMgr->getRootSceneNode()->attachObject(ent);
}
};



int main (void)
{
Example1 app;
app.go();
return 0;
}

所以编译过程不起作用。我目前正在使用Visual Studio 2010和OgreSDK_vc10_v1-7-3。

错误是

Answer 1

将主要功能的签名替换为以下内容：

INT WINAPI WinMain( HINSTANCE hInst, HINSTANCE, LPSTR strCmdLine, INT )

Answer 2

项目右下角

- ＆gt;属性链接器 - >子系统

使用“CONSOLE（/ SUBSYSTEM：CONSOLE）”

更改子系统

Answer 3

您的编译器认为该程序是一个Windows应用程序，但您的源代码是用于命令行应用程序。
