Xcode 配置了qpa的Qt4.8.6编译出现问题。

在MacOSX版本10.8.5上编译Qt4.8.6源代码时，我遇到以下错误

某些与平台相关的标志似乎未启用

我有用于10.7和10.8的Xcode Mac base SDK。

QPA是Qt平台抽象，您可以在其中为嵌入式系统开发自己的插件。它基本上取代了平台端口

QP5在QT5中有很好的发展，也许你可以考虑使用它。 您需要自己解决这些编译问题，如果您正计划如何使用QPA，最小插件是最佳选择

基本上，您可以通过包含ApplicationService框架和标题来解决这些问题。希望这有帮助

./configure -debug -opensource -confirm-license -arch "x86_64" -cocoa -qpa
