Mac OSX 10.5 SDK in Lion

With the release of Lion (OSX 10.7), they’ve stopped shipping the 10.5 SDK in X code. That’s a problem for me and the users of Ames Stereo Pipeline (ASP) since ISIS currently only builds against 10.5. If you are interested in building ASP on your new mac laptop, you’ll need to follow the instructions bellow to setup a development environment that is compatible with OSX 10.5.

You need the following:

  • Laptop with no install of XCode currently
  • The install dmg for XCode 4 or equivalent from the AppStore.
  • The install dmg for XCode 3.2.6

The older XCode version is available at ‘Downloads for Apple Developers’. Sadly you’ll need a registered Apple ID. Darn them!

Step 1
Install XCode 4 normally.

Step 2
Mount but don’t run the XCode 3.2.6. Inside that new volume you’ll find a hidden ‘Packages’ folder that contains MacOSX10.5.pkg. Run that and it will install the missing SDK to /Developer/SDKs/. 

> open xcode_3.2.6_and_ios_sdk_4.3.dmg
> cd /Volumes/Xcode\ and\ iOS\ SDK/Packages
> open MacOSX10.5.pkg

You might want to double check that the 10.5 SDK is installing into the /Developer folder and not just root.

Step 3
This old SDK is missing some symlinks to be compatible with the new Darwin 11. You’ll need to add them with the following commands. 

> cd /Developer/SDKs/MacOSX10.5.sdk/usr/include/c++/4.2.1
> sudo ln -s i686-apple-darwin9 i686-apple-darwin11
> sudo ln -s x86_64-apple-darwin9 x86_64-apple-darwin11

You are finished!
