I've just updated my iPhone SDK to v4 and am using Titanium 1.2.1 with the mobile SDK 1.2/1.3 and I'm having trouble building mobile projects for the emulator.
I've followed the instructions on the forum for replacing the LibTiCore.a file and I'm still running into difficulties. You can see the full output from the compile process at http://gist.github.com/452696 if that sheds any light on the situation.
I'm going to a full re-install to see if that works but in the meantime if anyone has any pointers they're very welcomed.
Sorry everyone. I should have read this (http://developer.appcelerator.com/blog/2010/06/1-3-2-1-4-rc1-release-now-available.html) first.
As you were…
