Apple LLVM Compiler 3.1 error clang

Question

I\'m trying to make an archive (ipa) for my iOS (iPhone) app but I\'m receiving a strange error:

Apple LLVM Compiler 3.1 error clang: error: no such file or          


        

Answer 1

OK, what you need to do is go to build settings and scroll down to :

Apple LLVM Compiler 3.1 - Language

Search in the table for 'other c flags'. What you see is armv6? Right? :)

Change armv6 to: -DNS_BLOCK_ASSERTIONS=1

Good luck, Nathan

1. Click on your project (Usually on top of your in-Xcode-file-browser - blue Xcode icon).
2. Go to [Your project] under Targets.
3. Click on the Build Settings.
4. Search in the search box for: 'other c flag'. (On mine there were three options - disregard all options except the bold 'Other C Flags.')
5. Click on the third column of 'Other C Flags' and enter: '-DNS_BLOCK_ASSERTIONS=1'

That should do it :)

(I also had some files missing, look at your build log and make sure there are no other errors above the one mentioned for this question)

Good luck!

P.S. - May Xcode die a slow and painful death!

Answer 2

I got similar error. Following steps fixed my problem, not sure if this is going to work for you, but worth a shot:

Issue: Compiler unable to locate [myapp]-Prefix.pch file. This is because Location of Prefix Header file [myapp]-Prefix.pch in Project Target is incorrect.

The location is defined in Project Target/Build setting. You will need to go to: Project Target -> Build Settings Tab -> Scroll down and Look for "Apple LLVM Compiler 3.1 - Language" Underneath this node -> You will find the key/value setting for Prefix Header file.

Normally Prefix header file is located under "Supporting File" Folder in your project

Please note, I am using Xcode 4.3.2 so if you are using a version other than this you might have to look around a bit for this setting.

Happy Coding!

For me I was referencing a PCH that didn't exist, just search for 'pch' in your build settings and make sure any .pch files being referenced actually exist at that location, if not, update
