子弹物理，Visual Studio 中的链接错误

Question

我在 Windows 7 和 Visual Studio 2012 上使用 Bullet Physics。我已经编译了库，并且演示工作正常，但是当我尝试创建自己的解决方案时，出现链接错误。我已将代码量降到最低

#include "btBulletDynamicsCommon.h"
int main(int argc, char*argv[])
{
    btBoxShape* box = new btBoxShape(btVector3(1, 1, 1));
    return 0;
}

当我链接时，使用 Visual Studio 会出现以下错误：

1>------ Build started: Project: HelloBulletApp, Configuration: Release Win32 ------  
1>  main.cpp  
1>  main.obj : MSIL .netmodule or module compiled with /GL found; restarting link with /LTCG;   add /LTCG to the link command line to improve linker performance

1>c:\path\to\HelloBulletApp\HelloBulletApp\Release\HelloBulletApp.exe : fatal error LNK1319: 6 mismatches detected

在调试或发布模式下构建时出现相同的错误。 我试过了：
- 重建子弹 2.81，
- 重新下载 2.81，
- 创建一个空白项目并添加库，
- 创建一个空白项目并按照http://bulletphysics.org/mediawiki-1.5.8/index.php/Creating_a_project_from_scratch 的建议添加项目， 但无济于事。

有什么我可以做的吗？

看起来 BulletCollision.lib 已编译为与 C 运行时库 (/MD) 的 DLL 版本链接，但您正在编译为与静态链接的运行时库 (/MT) 链接。更改编译器选项以链接 DLL 运行时库。
