cppunit在Mac OS X上与Clang链接错误

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;
}

我正在收到链接错误：

 clang: error: linker command failed with exit code 1 (use -v to see invocation)

我在调用clang时使用-lcppunit标志。当我在Linux计算机上运行Make File时，它会罚款。

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

在我/usr/local/lib/中。我什至尝试安装到/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。我正在使用libc ，因为我在项目中使用了std :: shared_ptr。问题是我尝试用libc 编译cppunit，但会引发链接错误。看来它必须与libstdc 一起编译，这需要我安装Fink或MacPorts，以便我可以安装最新版本的GCC和LibstDC 。我真的希望避免这种情况，因为会有一团糟的尝试来设置它。我真的也希望避免将Boost用于共享_ptr。

有可能吗？如果没有，我可能会屈服并安装Macports
