Legacy components for XCode 4/5/6/7 (deprecated compilers and Mac OS X SDKs).
Home page: http://devernay.free.fr/hacks/xcodelegacy
Many components were removed in recent versions of Xcode, the most notable being the Mac OS X 10.6 SDK, which is required to build software using the Carbon API (such as wxWidgets 2.8).
I made the script XcodeLegacy.sh to extract these components (the links work if you sign in to Apple Developer first) from Xcode 3.2.6, Xcode 4.6.3, Xcode 5.1.1 , Xcode 6.4 and install them in Xcode 4/5/6/7:
- GCC 4.0, GCC 4.2 and LLVM GCC 4.2 compilers
- GCC 4.0, GCC 4.2 and LLVM GCC 4.2 Xcode plugins
- PPC assembler
- Mac OS X SDK 10.4u, 10.5, 10.6, 10.7, 10.8, 10.9, 10.10
In order to re-enable the GCC 4.2 plugin in Xcode 4, you may also want to edit "/Applications/Xcode.app/Contents/PlugIns/Xcode3Core.ideplugin/Contents/SharedSupport/Developer/Library/Xcode/Plug-ins/GCC 4.2.xcplugin/Contents/Resources/GCC 4.2.xcspec" and change ShowInCompilerSelectionPopup to "YES" and IsNoLongerSupported to "NO".
Note: There may be similar tips to compile for older iOS (not Mac OS X) versions, but I don't develop for iOS. However, if you want to enhace the XcodeLegacy script to also include those components, I'll gladly integrate your modifications.
XcodeLegacy.sh (previous versions: 1.0, 1.1, 1.2)
Execute the script in a terminal. The script takes one argument, which can be "buildpackages" (to extract components from the legacy Xcode downloads to the current directory), "install" (to install the components in Xcode 4/5/6), "cleanpackages" (to delete the extracted components from the current directory), "uninstall" (to uninstall the components from Xcode 4/5/6).
With the "install" or "uninstall" arguments, the script uses sudo to become root, and will thus ask for your password. Please check the script contents before executing it.
To use any of the older SDKs, you should:
- compile and link with the options
-mmacosx-version-min=10.5 -isysroot /Developer/SDKs/MacOSX10.5.sdk - set the environment variable
MACOSX_DEPLOYMENT_TARGETto the proper value (e.g. 10.5) - this should be redundant with the-mmacosx-version-mincompiler option, but older compilers do not seem to pass this option to the linker.
For example:
env MACOSX_DEPLOYMENT_TARGET=10.6 clang -arch i386 -arch x86_64 -mmacosx-version-min=10.6 -isysroot /Developer/SDKs/MacOSX10.6.sdk main.c -o main
Links to the compilers are installed in /usr/bin (or /usr/local/bin on OS X 10.11 El Capitan): gcc-4.0 g++-4.0 gcc-4.2 g++-4.2 llvm-cpp-4.2 llvm-g++-4.2 llvm-gcc-4.2.
GCC 4.0, GCC 4.2 and LLVM GCC 4.2 cannot compile for OS X 10.10 or newer.
PowerPC architectures (ppc, ppc7400, ppc970, ppc64) cannot be linked for OS X 10.7 or newer.
