问题描述
我正在使用Xcode构建旧代码并指定SDKROOT=/Developer/SDKs/MacOSX"${HOST_VERSION}".sdk/
I am using Xcode to build an old code and specify SDKROOT=/Developer/SDKs/MacOSX"${HOST_VERSION}".sdk/
我想为系统上预装(?)的最新SDK指定SDKROOT.例如我已经在10.8上，并且想用-syslibroot指定SDKROOT，但是/Developer/SDKs/中没有这样的SDK.如果SDK_VERSION == HOST_VERSION，我应该完全忽略syslibroot吗?
I want to specify SDKROOT for latest SDK that comes pre-installed (?) on the system. e.g. I am on 10.8 already and I want to specify SDKROOT with -syslibroot, but there is no such SDK in /Developer/SDKs/. Should i just ignore syslibroot altogether if SDK_VERSION == HOST_VERSION?
推荐答案
较新的Xcode版本在Xcode.app软件包中包含SDK，例如
Newer Xcode versions have the SDKs inside the Xcode.app bundle, e.g.
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk
通过运行，您将获得已安装的SDK列表及其路径.
You get the list of installed SDKs together with their path by running
xcodebuild -sdk -version
从命令行.
如果已安装命令行工具"(Xcode首选项->下载->组件)，则没有"-syslibroot"的编译应等同于针对最新的SDK进行编译.
If you have installed the "Command Line Tools" (Xcode Preferences -> Downloads -> Components) then compiling without "-syslibroot" should be equivalent to compiling against the latest SDK.
请参阅命令行工具"软件包的帮助:
