我正在尝试在 Visual Studio 2010 中编译简单的单元测试项目。我有一个 testrunner.cpp：

#define BOOST_TEST_DYN_LINK

#define BOOST_TEST_MODULE "BaumWelch Unit Tests"
#include <boost/test/unit_test.hpp>

和exampletests.cpp

#include <boost/test/unit_test.hpp>

int add( int i, int j ) { return i+j; }

BOOST_AUTO_TEST_CASE( my_test )
{
  // seven ways to detect and report the same error:
  BOOST_CHECK( add( 2,2 ) == 4 );        // #1 continues on error
  BOOST_REQUIRE( add( 2,2 ) == 4 );      // #2 throws on error

  if( add( 2,2 ) != 4 )
     BOOST_ERROR( "Ouch..." );            // #3 continues on error

  if( add( 2,2 ) != 4 )
    BOOST_FAIL( "Ouch..." );             // #4 throws on error

  if( add( 2,2 ) != 4 ) throw "Ouch..."; // #5 throws on error

  BOOST_CHECK_MESSAGE( add( 2,2 ) == 4,  // #6 continues on error
    "add(..) result: " << add( 2,2 ) );
  BOOST_CHECK_EQUAL( add( 2,2 ), 4 );      // #7 continues on error
}

此示例在 Linux 中运行良好，但此处无法编译：

1>InitializeBuildStatus:

我做错了什么，我该如何解决？

编辑：应用 Arne Mertz 的答案后，我得到：

检查项目的链接器属性：有一个属性System/SubSystem应该设置为/SUBSYSTEM:CONSOLE.

编辑： 对于多重定义错误，您似乎有以下情况：在您的 testrunner.cpp 中，您定义BOOST_TEST_DYN_LINK了一个动态链接，boost_unit_test_framework-vc100-mt-1_46_1.dll其中包含 master_test_suite 函数的定义。在另一个 .cpp 中，您不定义该符号，以便一个静态链接到该符号，boost_unit_test_framework-vc100-mt-1_46_1.lib与 dll 一起给出两个定义。

解决方案：#define在包含标题之前在每个源中使用。
