I assume you realise that you won’t be able to build Audacity unless you also have Xcode 3 and Xcode 4, nor (for that reason) will you likely be able to build Audacity on a machine that started with a Mavericks install.
If you really want to change the Widgets configurations, you can amend the widgets build script available on the above page so that it only builds release (or if you are going to join Audacity as a developer, only builds debug).
If that’s the case then are the earlier Xcode versions only required because of their associated platform SDKs (giving the ability to target older versions of OSX) or is there actual code that requires the earlier versions? That is, is it possible to build an OSX 10.9-only version of Audacity?
No, I’m just trying to get a build working on OSX but I don’t want to revert to older OSs to do this. I’m also not interested in PPC. I was hoping that this might be possible but it’s not clear how difficult this would be to actually do.
