c – 使用Visual Studio 2010的CATCH单元测试套件

据我了解,我可以简单地将catch.hpp放入我的项目目录,将其添加到项目中,然后开始编写测试.一旦我尝试使用 tutorial中概述的一些宏,我就遇到了一些或者11个确切的链接器错误.

#include "catch.hpp"

unsigned int Factorial( unsigned int number ) {
    return number <= 1 ? number : Factorial(number-1)*number;
}

test_CASE( "Factorials are computed","[factorial]" ) {
    requIRE( Factorial(1) == 1 );
    requIRE( Factorial(2) == 2 );
    requIRE( Factorial(3) == 6 );
    requIRE( Factorial(10) == 3628800 );
}

我能够在第一个例子中创建一个文件并用g编译它,但是当我只是将相同的代码粘贴到我的VS2010项目中然后尝试运行它时,我遇到了链接器错误.不幸的是,我现在还不熟悉C来自己解码错误,在看了单个文件here之后,我无法辨别出这个问题.
