This error arises when another process is running, as indexing in Xcode, when you launch the first compilation with the preparation of the code.
The project preparation is now done after the end of the first compilation, to avoid such a conflict.
But there isn't another process running when I start my build (according to the little window at the top-center of my xcode screen). Here's what I'm doing, tell me if I'm doing something wrong.
- Create a new project on my local hard drive (not my network drive)
- I make a small change to makefile - for excluded libraries, I replace OneWire with panstamp (because panstamp.h give me build errors)
- I make sure the window at the top center of xcode doesn't show anything processing.
- I select Build as my target and then click Run button
And I have the problem I mentioned where the project isn't loaded and won't load when I try to re-open.
I've even tried waiting a few minutes before doing my build just to make sure, even though xcode isn't showing anything processing.
When I do the exact same thing with release 42, it works fine. I've even reinstalled release 42, made sure it worked then installed release 45 again and I get this problem.
