macos - 无法在 Snow Leopard 上使用 Qt 构建

Question

我安装了 Qt 并尝试在 QtCreator 中构建一个模板项目（Qt4 Gui Application）。我无法弄清楚为什么我会收到这些错误。

为项目 SourceControl 运行构建步骤...
配置不变，跳过 QMake 步骤。
开始：/usr/bin/make -w
make: 进入目录`/Users/jason/SourceControl'

make: *** [main.o] 错误 1

构建项目 SourceControl 时出错
执行构建步骤“Make”时

Answer 1

我不确定，但我想你应该关注第一个错误，它说它找不到AvailabilityMacros.h。我认为这应该在 /usr/include 中，但我猜它可能不是，因为您的编译行清楚地表明它是包含路径之一。

find如果它不在那里，您可以尝试通过在命令行上使用来找出它在哪里，例如。

find /usr -name AvailabilityMacros.h

或 Mac 上可用的任何 GUI 方法（您可以说我对 MacOS 不太熟悉 :)）。顺便说一句，如果上述find命令没有产生任何结果，那么您可以将搜索范围从 扩大/usr到/.

回应您发布的find结果：

您是否正在尝试针对 MacOSX10.5.sdk 构建您的应用程序？如果不是，那么我认为这不是您想要的版本。如果您使用的是 10.5 SDK，那么您需要将QMAKE_MAC_SDKqmake 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->Build steps 中将其设置为 qmake 的附加参数。

Answer 2

谢谢，游吟诗人。通过将以下行添加到项目的 .pro 文件中，我能够解决该问题：

QMAKE_MAC_SDK = /Developer/SDKs/MacOSX10.5.sdk

我更愿意针对 Mac OS X 10.6 SDK 构建，但 /Developer/SDKs 中没有这样的目录。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 文件中删除上面指示的行并成功编译。
