CppUnit在Mac OS X上與Clang鏈接錯誤

Question

我正在嘗試使用CppUnit編譯測試程序。問題是，這個示例代碼：

//[...] 

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; 
} 

我收到鏈接錯誤：

調用鐺當我使用-lcppunit標誌。當我在我的Linux機器上運行make文件時，它編譯得很好。

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

在我的/ usr/local/lib /中。我甚至嘗試安裝到/ usr/lib併發生相同的鏈接錯誤。任何幫助將不勝感激。

非常感謝！

編輯：我想通了這個問題。我正在使用libC++，因爲我在我的項目中使用了std :: shared_ptr。問題是我試圖用libC++編譯CppUnit，但它會引發鏈接錯誤。看來它必須用libstdC++編譯，這需要我安裝Fink或Macports，這樣我才能安裝最新版本的gcc和libstdC++。我真的希望能夠避免這種情況，因爲嘗試設置它會導致一團糟。我真的也希望避免爲shared_ptr使用Boost。

這是可能的嗎？如果沒有，我可能會放棄並安裝MacPorts

我有同樣的問題。將「C++標準庫」設置爲「libstdC++（GNU C++標準庫）」後可以。
