Apple LLVM Compiler 4.2 Error

Question

I'm getting this error message whenever I try to compile my xcode project, I've been around searching and applying answers from other related questions, and still not able to solve the issue, so I post this specific question. How can I fix this?

Answer 1

It appears that this has something to do with my libraries compiling version. For anyone who has the same problem or close to this problem, please make sure you got the lastest libraries from your device's manufacturers.

Answer 2

This looks suspicious:

-I/Users/ObsidianSword/Dropbox/Company -I- -IiOS -IProjects -IFolder/Official -IProjects/Project -ISolution "-I(Company" "-I3.3.3.2)/../ReaderAPI-iOS-0.7/ReaderAPI-iOS-0.7"

It looks like you have an include path that really should just be

-I"/Users/ObsidianSword/Dropbox/Company - iOS Projects Folder/Official Projects/ProjectName (Company 3.3.3.2)/../ReaderAPI-iOS-0.7/ReaderAPI-iOS-0.7"

or something similar, but it is probably missing quotes to account for the spaces in the file path. I would look for something like that in your Xcode project settings and wrap the full path in quotes.

Answer 3

as far as i seen the crash log. I think you have set a wrong library path with '-I'

-I/Users/ObsidianSword/Library/Developer/Xcode/DerivedData/ProjectName-bkinddajwtvxeybjhjlenxyuhuxu/Build/Products/Debug-iphonesimulator/include

as you can see it at the staring of the path, which is not supported by Apple LLVM Compiler. Fix it and your problem will be resolved.

Answer 4

For anyone who is getting LLVM compiler 4.2 error and for whom above solution did not work, Try clean+build or restart XCode / Mac. In my case restarting Xcode did not work but restarting Mac fixed the issue.
