Xcode make和xcrun版本的强制SDK错误 我试图用XC++和命令行工具12.2在10.15系统上用C++编写代码< >代码> 。它一直希望使用不支持arm64的10.15 SDK。因此，我得到了体系结构不受支持的错误

我的make文件包含：

SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.0.sdk

-isystem /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.0.sdk

而build命令包含：

SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.0.sdk

-isystem /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.0.sdk

奇怪的是：

xcrun --show-sdk-path
/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk

xcrun --show-sdk-version
xcodebuild: error: SDK "/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk" cannot be located.
xcrun: error: unable to lookup item 'SDKVersion' in SDK '/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk'

有什么想法吗？以前在Xcode 11.7上有一个干净的安装，然后我复制了12.2（替换了11.7）。我已经验证了SDK（v15）存在于

/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.SDK

，并且OSX11 SDK也在SDK文件夹中

x86_64的构建工作正常
