Xcode 3.1.2 locks up when loading C++ project...?

Question

I have a project which builds correctly from the command line. On one of my Macs (10.5) running Xcode 3.1.2, I can load it and build it in the Xcode IDE. On my other Mac (same configuration of software), Xcode sometimes loads the project, but always locks up with a spinning beach ball at some point before the build is done. Sometimes this occurs as the project is loaded, sometimes late in the build.

I've tried doing a 'clean' on the project, I've tried pulling in the source code fresh from source control. So far, no luck -- I have to kill Xcode and in effect, cannot develop on this particular Mac. I've uninstalled and reinstalled Xcode.

Any clues?

Answer 1

Try deleting the project index (.pbxindex) from the build folder.

Answer 2

I finally got it to work by deleting the Xcode cache in ~/Library/Caches/com.apple.Xcode
