Question

我正在尝试使用CppUnit编译测试程序。问题是，使用此示例代码：

//[...]

class EntityComponentTest : public CppUnit::TestFixture
{
CPPUNIT_TEST_SUITE( EntityComponentTest );
CPPUNIT_TEST( testGetComponents );
CPPUNIT_TEST_SUITE_END();
Entity e;


public:
void setUp(){
    e.addComponent("1", new TestComponent("Hello 1"));
    e.addComponent("2", new TestComponent("Hello 2"));
}

void tearDown(){}

void testGetComponents()
{
    TestComponent &first = static_cast<TestComponent&>(e.getComponent("1"));
    TestComponent &second = static_cast<TestComponent&>(e.getComponent("2"));

    CPPUNIT_ASSERT(first.msg == "Hello 1");
    CPPUNIT_ASSERT(second.msg == "Hello 2");

}


};
CPPUNIT_TEST_SUITE_REGISTRATION( EntityComponentTest );
int main(void)
{
//followed from tutorial
CppUnit::TextUi::TestRunner run;
CppUnit::TestFactoryRegistry &r = CppUnit::TestFactoryRegistry::getRegistry();
run.addTest(r.makeTest());

run.run("", false, true);

return 0;
}

我收到链接错误：

我在调用clang时使用-lcppunit标志。当我在我的Linux机器上运行make文件时，它编译得很好。

libcppunit-1.12.1.0.0.dylib
libcppunit-1.12.1.dylib
libcppunit.a
libcppunit.dylib

在我的/ usr / local / lib /中。我甚至尝试安装到/ usr / lib并发生相同的链接错误。任何帮助将不胜感激。

非常感谢！

编辑：我发现了问题所在。我正在使用libc ++，因为我在我的项目中使用std :: shared_ptr。问题是我尝试用libc ++编译CppUnit但它会引发链接错误。它似乎必须用libstdc ++编译，这需要我安装Fink或Macports所以我可以安装最新版本的gcc和libstdc ++。我真的希望避免这种情况，因为试图设置它会有一团糟。我真的也希望避免在shared_ptr中使用Boost。

这有可能吗？如果不是，我可能会放弃并安装MacPorts

我有同样的问题。将“C ++标准库”设置为“libstdc ++（GNU C ++标准库）”后即可。

CppUnit在Mac OS X上与Clang链接错误
