I am having Xcode 4.4 on OS X Lion. I'd like to install the Mac 10.6 SDK - also known as macosx10.7 SDK - because I need to compile openFrameworks.
I found that I need to download additional tools from this site. However I didn't find any 10.6 SDK there. I also tried looking in Xcode Preferences -> Downloads -> Components, but there is no way.
I am wondering how can I install previous SDKs for Xcode?
