我正在尝试使用 CppUnit 编译一个测试程序。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 时使用了 -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/. 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++,因为我在我的项目中使用了 std::shared_ptr。问题是我尝试使用 libc++ 编译 CppUnit,但它会引发链接错误。看来它必须用 libstdc++ 编译,这需要我安装 Fink 或 Macports,这样我才能安装最新版本的 gcc 和 libstdc++。我真的希望避免这种情况,因为尝试设置它会一团糟。我真的也希望避免对 shared_ptr 使用 Boost。
这有可能吗?如果不是,我可能会放弃并安装 MacPorts
