构建Qt消息传递框架在Mac

我试图从OS X 10.6的Git源构建最新版本的QMF的，但我一直运行到这个错误：构建Qt消息传递框架在Mac

ld: symbol(s) not found for architecture x86_64

它，然而，编译在Ubuntu和我接近足够积极我已经编译它在OS X之前，所以我有点困惑，明显的符号没有发现通常意味着有一些源代码丢失，任何人都会在我开始撕裂它之前碰到这个？

“ ld：找不到架构x86_64的符号“这看起来很腥。你是否与适当的库链接（如果有的话）？ [这个链接]（http://qt-project.org/forums/viewthread/5665）也可能是相关的。 –

这可能是我编译Qt时的一些问题，但通常当你抛开一个方法定义时，它会抛出同样的警告。 –

发生此错误是因为编译器忽略了远离库的未引用类。我能够通过添加以下代码都明确模板实例后（或只需将其添加到文件末尾）在的src \库\ qmfclient \ qmailinstantiations.cpp来解决此问题：

class reference_holder 
{ 
    struct helper 
    { 
     helper(QPrivatelyImplemented<QMailMessageBodyPrivate>* = 0) 
     { 
     } 

     ~helper() 
     { 
     } 
    }; 

    static helper helper_; 

    static void use_helper() 
    { 
     (void)helper_; 
    } 

    template<void(*)()> 
    struct helper2 {}; 

    static helper2<&reference_holder::use_helper> helper2_; 
};
