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 directory: 'armv6'

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

Does anyone know how i can fix this?

You'll need to show more than that. What was the entire command line that was being run? — mattjgalloway, Feb 26 '12 at 21:51
Looks like you've got a rogue setting somewhere as it thinks armv6 is a file and the command line confirms that's what's happening. My suggestions is search the build settings for armv6 and check it's not randomly in there for some setting. — mattjgalloway, Feb 26 '12 at 22:36

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

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

Image of what It should Look like when you're done

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!

This didn't solve the problem for me. I was getting the same error but it was because I was accidentally trying to set a value in NSLog. e.g. NSLog(@"%@", [[defaults setObject:@"test"] forKey:@"Test"]); — , Mar 10 '12 at 13:21
I found 6 questions like this with the same answer but my solution was this one. Thanks for the answer. — Jacksonkr, Sep 29 '14 at 17:57

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!

Make sure you are getting an error in your error log for this - It messes it up if you're not :P — Tyler Wall, Jul 19 '12 at 21:27
+1 Thanks! That solved my problem. I was restructuring my files and later on, I was unable to build since it could not find my pch file. Great help. Thanks :) — Dexter, Aug 20 '12 at 21:33

I had this same issue and none of the above answers were working for me.

I discovered that if I opened a project from the command line, i.e. open test.xcodeproj/, even a brand new project from a template would fail to compile with the error above.

However, if I opened Xcode first and chose the project from the splash screen, everything worked just fine.

Leaving this here in case anyone else is stuck banging their head against the wall.

I had this problem

You are using this compiler flags in your build Phases --> Compile Sources

File.m  -fno-objc-arc armv6

Replace it to:

File.m  -fno-objc-arc

I got similar error, it seems there have many solutions to fix it, maybe.

Project Setting -> Building Setting -> Apple LLVM compile 3.1 - Launguage -> Objective-C Automatic Reference Counting. The default value is YES, modify it to NO.

My Xcode version is 4.3.2.

Hope this could help you and all the reader.

I got the same error for LLVM Compiler 4.1 and it says that it could not found the file(s). I clean the project and open the Build Phases from Targets/Target section and remove all irrelevent files then rebuild the project and it worked.

Also in build configuration you can change "Compiler for C/C++/Objective-C" to Default Compiler (Apple LLVM compiler 3.1)

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

I had this issue with an unchanged project which had built fine before. The issue turned out to be the RAM Disk that I was using for XCode intermediate files being full!

XCode was reporting this and other issues which were solved by deleting older intermediate files.
