MacOSX-SDKs
10.1.5 - 11.3
A collection of those pesky SDK folders. Compiled from various releases of Xcode.
If you don't need this entire repository, each SDK is available here.
Outdated versions: mediafire / mega.co.nz / mediafire / mega.co.nz.
Important
Modern versions of Xcode (7.3+) need you to edit the MinimumSDKVersion in this file to use older SDKs:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Info.plist
Usage
Set the SDKROOT environment variable:
export SDKROOT=path-to-old-sdk
If you put an old SDK in a nonstandard path, Apple's hacks in /usr/bin which redirect to calling Apple's tools in the XCode installation may fail. If your build system fails to find the compiler, explicitly specify its path:
export CC="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang"
export CXX="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++"
If you are building a project with CMake, using the default Unix Makefile generator may fail to
find the real make binary even if you put it in your $PATH before /usr/bin. To hack around this, install
Ninja in your $PATH and use the Ninja CMake generator by running your CMake
configure step with:
cmake -G Ninja -S project-root-dir -B build-output-dir
