我安装了Qt并尝试在QtCreator中构建模板项目（Qt4 Gui Application）。我无法弄清楚为什么我会收到这些错误。

答案 0 :(得分：3)
我不确定，但我猜你应该专注于第一个错误，它说它无法找到AvailabilityMacros.h。我认为应该在/ usr / include中，但我猜它可能不是因为你的编译行清楚地表明它是包含路径之一。
如果不存在，您可以尝试通过在命令行上使用find找出它的位置，例如。
find /usr -name AvailabilityMacros.h
或Mac上可用的任何GUI方法（你可以告诉我，我不熟悉MacOS :)）。顺便说一句，如果上述find命令无效，那么您可以将搜索范围从/usr扩展为/。
回复您发布的find结果：
您是否正在尝试针对MacOSX10.5.sdk构建应用程序？如果没有，那么我认为这不是你想要的版本。如果 使用10.5 SDK，则需要将QMAKE_MAC_SDK qmake变量设置为/Developer/SDKs/MacOSX10.5.sdk。您可以在项目文件中执行此操作，也可以在Projects-＆gt; Build steps中将其设置为qmake的附加参数。
答案 1 :(得分：0)
谢谢Troubadour。我能够通过在项目的.pro文件中添加以下行来解决问题：
QMAKE_MAC_SDK = /Developer/SDKs/MacOSX10.5.sdk
我更愿意针对Mac OS X 10.6 SDK进行构建，但/ Developer / SDK中没有此类目录。如果您知道我在哪里可以找到10.6 SDK，请告诉我。
编辑：更新到最新版本的Xcode后，我能够从项目的.pro文件中删除上面指定的行并成功编译。
