SDKROOT path for latest SDK

Question

I am using Xcode to build an old code and specify SDKROOT=/Developer/SDKs/MacOSX\"${HOST_VERSION}\".sdk/

I want to specify SDKROOT for latest SDK that comes

Answer 1

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

You get the list of installed SDKs together with their path by running

xcodebuild -sdk -version

from the command line.

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.

See the help to the "Command Line Tools" package:

Downloading this package will install copies of the core command line tools and system headers into system folders, including the LLVM compiler, linker, and build tools.
