Question

I am building an iOS 4.2+ game using Xcode 4.1 and Pixelwave, on OS X Lion.

At one point during the development, I did a Clean of the project, and ever since I have been unable to compile the project, as I get an enormous number of errors when it processes the PCH. Here is the invocation and the first few bunches of errors reported:

As far as I can tell, nothing had changed in the build settings that would have triggered this.

Here is what I have tried, unsuccessfully, while attempting to debug this:

• Reverting to a previous commit of my project that had previously compiled ok.
• Checking out a fresh copy of Pixelwave.
• Reverting to the first commit of my project that had previously compiled ok.
• Deleting the DerivedData subdirectory for the project.
• Restarting Xcode.
• Rebooting.
• Uninstalling and reinstalling dev tools (I was getting desperate).

None of this has helped—I still encountered the same errors every time. I am at my wits’ end as to what is causing this behaviour. I don’t even know where to start looking.

Answer 1

Following a suggestion from another user, I copied all the source files into a new project, and got that to build. Doing a diff of the two project files then revealed one of the very few meaningful differences was ALWAYS_SEARCH_USER_PATHS, set to YES in the project that wouldn’t build.

Setting ALWAYS_SEARCH_USER_PATHS back to the default NO fixed the problem.
