boost测试库：多重定义错误

Question

我正在尝试测试我在QTCreator for Windows中完成的（微积分）库。

我已经创建了一个主文件，并在测试的单独文件中创建了一个类。如果我编译在http://www.boost.org/doc/libs/1_47_0/libs/test/doc/html/utf/user-guide/test-organization/manual-test-suite.html中找到的示例，它的工作原理，因此在http://www.boost.org/doc/libs/1_47_0/libs/test/doc/html/utf/user-guide/test-organization/manual-nullary-test-case.html中找到的示例也适用。

但是，当我尝试编译我的项目，我有很多（超过500）多个定义的错误。下面你可以找到我的文件。正如你所看到的，我也试图在boost头文件中加入一些防范措施，但它不起作用。我究竟做错了什么？

的main.cpp

#include "testcalculus.h" 

#ifndef USE_BOOST_HEADERS 
#define USE_BOOST_HEADERS 
#include <boost/test/included/unit_test.hpp> 
#include <boost/bind.hpp> 
#endif 

using namespace boost::unit_test; 

test_suite* 
init_unit_test_suite(int argc, char* argv[]) 
{ 
    WRayTesting::TestCalculus xTestCalculus; 

    test_suite* pxTestSuiteCalculus = BOOST_TEST_SUITE("Test Calculus"); 

    pxTestSuiteCalculus->add(BOOST_TEST_CASE(boost::bind(&WRayTesting::TestCalculus::testCartesianPoint2D, &xTestCalculus))); 

    framework::master_test_suite().add(pxTestSuiteCalculus); 

    return 0; 
} 

testcalculus.h

#ifndef TESTCALCULUS_H 
#define TESTCALCULUS_H 

#ifndef USE_BOOST_HEADERS 
#define USE_BOOST_HEADERS 
#include <boost/test/included/unit_test.hpp> 
#include <boost/bind.hpp> 
#endif 

#include "cartesianpoint2d.h" 
#include "cartesianvector2d.h" 

namespace WRayTesting 
{ 

/** Class for testing the Calculus project */ 
class TestCalculus 
{ 
public: 

    //! Constructor 
    TestCalculus(); 

    //! Testing class point 
    void testCartesianPoint2D(); 

private: 

}; 

} // namespace WRayTesting 

#endif // TESTCALCULUS_H 

testcalculus.cpp

#include "testcalculus.h" 

#ifndef USE_BOOST_HEADERS 
#define USE_BOOST_HEADERS 
#include <boost/test/included/unit_test.hpp> 
#include <boost/bind.hpp> 
#endif 

namespace WRayTesting 
{ 

using ::Calculus::CartesianPoint2D; 
using namespace boost::unit_test; 


/** 
* Constructor 
*/ 
TestCalculus::TestCalculus() 
{ 

} 

/** 
* Test the CartesianPoint2D class. 
*/ 
void TestCalculus::testCartesianPoint2D() 
{ 
    // Default constructor 
    CartesianPoint2D xTestingPoint; 
    BOOST_CHECK(0.0 == xTestingPoint.getX()); 
    BOOST_CHECK(0.0 == xTestingPoint.getY()); 

} 

} // namespace WRayTesting 

编译输出

您不能在同一测试模块中的多个文件中包含#include。您可能需要切换到库或将所有内容放入单个文件中
