在Qt5上去静态库:架构的未定义符号x86_64:

Question

我在Qt5中使用了一个go构建静态库，我通过以下方式将其添加到.pro文件中：

LIBS += /Users/xxxx/Desktop/xxxxxx/framework/xxxx.a

当我编译时，它给了我这个错误：

Undefined symbols for architecture x86_64:
"_SecCertificateCopyNormalizedIssuerContent", referenced from:
_isRootCertificate in xxxx.a(000021.o)
"_SecCertificateCopyNormalizedSubjectContent", referenced from:

但是当我使用nm xxxx.a时，我确实看到了符号：

怎么了？如何解决这个问题？
我试图clean并运行qmake.然而，它没有用。
我还尝试重新编译静态库，不幸的是，它也不起作用。

上面提到的所有符号都在Apple的Security框架中。
查看此链接以获取更多详细信息：链接。
我通过在.pro文件中添加以下代码片段来解决它。

macx {
LIBS += -framework Security
}

全部清理，运行 qmake 并运行它。错误现在应该消失了。
