Question

我正在尝试在我的mavericks机器上编译Qt应用程序但是在下面得到编译错误。

我已通过设置QMake变量

将部署目标设置为10.9

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.9

这还没有解决问题。我怀疑Qt正在使用错误的OSX框架进行编译：

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/的 MacOSX10.8.sdk

什么时候应该使用

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/的 MacOSX10.9.sdk

有没有人遇到这样的问题并找到了解决方案？

编译输出：

你用qt5配置了什么？您可以传递配置标志 -sdk /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk 。这会将sdk设置为macosx 10.9。从我看到的这与升压系统库有关。我想你正在使用一个boost库。只需链接Boost.System，它应该在/ opt / local / lib / libboost_system中。

在OSX 10.9上部署Qt 5.2.1 app时的链接器错误
