Question

这是我第一次在C ++（Visual Studio 2010）中准备一个非常复杂的应用程序，而且我遇到了严重的链接问题，让我头疼不已（可能因为我从来没有得到它的全部内容）。

我正在使用以下方法实施流体流动模拟器： - NVidia PhysX（SDK 3.2.3） - glew（1.9） - freeglut（2.8.1） - gltools库（OpenGL Superbible 5th的插件）

我不知道如何正确设置Release / Debug和MD / MDd / MT / MTd选项以使一切正常。

我可以使用MD / MDd / MT / MTd以及Relese / Release-Static / Debug / Debug-Static解决方案配置编译freeglut
我可以使用MD / MDd / MT / MTd以及Relese / Debug
PhysX是预编译的lib和dll文件（我不知道在编译过程中使用了哪些选项）
同样是关于glew

我尝试了很多配置，但总是遇到像

这样的编译错误

defaultlib 'MSVCRT' conflicts with use of other libs;

或

fatal error C1189: #error :  Exactly one of NDEBUG and _DEBUG needs to be defined by preprocessor

我读到这是关于以正确的方式设置所提到的配置，但我实际上做不到。

什么应该是正确的配置（以及为什么？）和哪些库应该与lib文件链接，哪些与dll链接？我是C ++的新手，所以请尽量解释清楚。

这是我的应用程序的“包含部分”（它非常相似，并且在我意外破坏之前它有效）：

//#define WIN32
#include <windows.h>        // Must have for Windows platform builds

#include <GLTools.h>
#include <GLFrustum.h>
#include <GLBatch.h>
#include <GLMatrixStack.h>
#include <GLShaderManager.h>
#include <GLGeometryTransform.h>
#include <StopWatch.h>

//#define GLEW_STATIC
#include <GL\glew.h>            // OpenGL Extension "autoloader"
//#define FREEGLUT_STATIC
#include <GL\freeglut.h>
//#include <GL\gl.h>            // Microsoft OpenGL headers (version 1.1 by themselves)

#include <math.h>
#include <stdio.h>
#include <iostream>

using namespace std;

#include <PxPhysicsAPI.h> 
#include <extensions/PxExtensionsAPI.h> 
#include <extensions/PxDefaultErrorCallback.h>
#include <extensions/PxDefaultAllocator.h> 
#include <extensions/PxDefaultSimulationFilterShader.h>
#include <extensions/PxDefaultCpuDispatcher.h>
#include <extensions/PxShapeExt.h>
#include <foundation/PxMat33.h> 

#include <pxtask/PxCudaContextManager.h>
#include <physxprofilesdk\PxProfileZoneManager.h>

#include <extensions/PxSimpleFactory.h>

#pragma comment(lib, "PhysX3_x86.lib")
#pragma comment(lib, "PhysX3Common_x86.lib") 
#pragma comment(lib, "PxTask.lib")
#pragma comment(lib, "PhysX3Extensions.lib")
#pragma comment(lib, "PhysXProfileSDK")

我不确定如果一切顺利的话，是否有必要使用最后一条车道（在谷歌的某个地方找到它并且有效）。

如果您需要更多信息或更详细的错误日志和一些配置，请告诉我，我会提供。

提前致谢！

没有d的所有东西（/ MD / MT）：

c:\dev\soft\physx-3.2.3_pc_sdk_core\include\foundation\pxpreprocessor.h(318): fatal error C1189: #error :  Exactly one of NDEBUG and _DEBUG needs to be defined by preprocessor

并且它只是lib文件的一种配置。我可以用其他方式编译gltools和freeglut，或者以其他方式设置#define GLEW_STATIC或#define FREEGLUT_STATIC ...这对新手来说太多了。：）

还有一个：

这是所有这些PhysX编译指示评论。

Answer 1

可能指向解决方案的一件事是，physx 3.2.3 lib文件是使用/ MT选项构建的，如文档中所示（这是文档文件夹中physx zip的一部分）：

“注我们通过Windows二进制分发提供的静态库与多线程静态C运行时（CRT）库链接。这意味着您的应用程序还必须使用相同的CRT风格。如果您需要使用其他CRT版本，则必须升级到我们的源许可证。可以使用不同的CRT设置简单地重新编译源分发。 “ 因此，如果您计划链接这些，则必须对所有其他库使用/ MT标志。

Answer 2

在包含物理标头的文件中添加#define NDEBUG。这将删除您的NDEBUG问题。

如何正确链接和包含库？
