从 XCode 4.3 + llvm 3.1 升级到 XCode 4.5 GM 后,我开始收到以下链接器错误。我已验证定义“_InvokeBridge”的静态库已正确链接。
知道什么可能导致错误吗?此外,是否有一般调查 Mach-o 链接器错误的提示?
undefined symbols for architecture i386:
"void pplx::details::_UnrealizedChore::_InvokeBridge<pplx::details::_PPLTaskHandle<std::__1::shared_ptr<BI::Url const>, pplx::task<std::__1::shared_ptr<BI::Url const> >::_InitialTaskHandle<std::__1::shared_ptr<BI::Url const>, BI::ServicesDocumentSession::GetViewUriAsync()::$_3, pplx::details::_TypeSelectorNoAsync>, pplx::details::_UnrealizedChore> >(pplx::details::_PPLTaskHandle<std::__1::shared_ptr<BI::Url const>, pplx::task<std::__1::shared_ptr<BI::Url const> >::_InitialTaskHandle<std::__1::shared_ptr<BI::Url const>, BI::ServicesDocumentSession::GetViewUriAsync()::$_3, pplx::details::_TypeSelectorNoAsync>, pplx::details::_UnrealizedChore>*)", referenced from:

非常感谢,A
