clang: error: no such file or directory: '/Users/waterskiingmithrill/Development/iPhone/Event/Event_Prefix.pch'

Question

I've messed up my iPhone project. I ran svn update, having fiddled with the repository months ago. Many changes since, make recovering from an old point nearly impossible.

When I attempt to build the project now I get:

clang: error: no such file or directory: '/Users/waterskiingmithrill/Development/iPhone/Event/Event_Prefix.pch'
clang: error: no input files
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

And I have no idea why Event_Prefix.pch is not there to be clanged. (I don't even know what clang is) Any help, suggestions on how to debug, tips on how to fix, greatly appreciated.

Solution 1

Clang is the compiler. Make sure you have a Event_Prefix.pch file in your project file.

Solution 2

I was having this just on a test build. Seems the test target did not update a naming change.

Solution 3

In my case, my search paths were not recursive.
