Qt5找不到目标条件

Question

我刚刚更新到OS X Mavericks中的最新版本的命令行工具,现在在编译我的(以前工作的)代码时会抛出以下错误

> clang: warning: no such sysroot directory:
> '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk'

有谁知道如果改变这一行

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

从sdk 8到9会起作用吗？如果是这样,我可以在Qt5的参数中改变这个吗？

Answer 1

对于其他人的参考,我通过编辑我的平台mkspec文件解决了这个问题:

/users/nic/Qt/5.3/clang_64/mkspecs/qdevice.pri

更改以下行:

!host_build:QMAKE_MAC_SDK = macosx10.8

对此:

!host_build:QMAKE_MAC_SDK = macosx10.9

务必清理项目并再次运行qmake.

NIC.

Answer 2

也可以通过在.pro文件中添加以下行来编译项目

QMAKE_MAC_SDK = macosx10.9

Answer 3

如果您在OS X之外的其他平台上进行编译,那么BRabbit27解决方案的改进将是:

macx {
QMAKE_MAC_SDK = macosx10.9
}

Answer 4

我刚刚升级到XCode 9,我开始在macOS Sierra上解决这个问题(10.12).问题是Xcode将默认符号链接移动到10.13.修理:

cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
sudo ln -s MacOSX.sdk MacOSX10.12.sdk

Answer 5

在Qt 5.5,MacOS 10.10.4中遇到了同样的问题.我从项目目录中删除了.qmake.conf和.qmake.stash.

Answer 6

我发现项目根目录中的文件".qmake.cache"引用了Mac OS 10.8.解决方案是删除文件并从头开始构建项目.
