file is universal (3 slices) but does not contain a(n) armv7s slice error for static libraries on iOS, anyway to bypass?

up vote 57 down vote favorite 17

I upgraded xcode version and when using external static libraries I get this message: ld: file is universal (3 slices) but does not contain a(n) armv7s slice: /file/location for architecture armv7s clang: error: linker command failed with exit code 1 (use -v to see invocation) is there anyway to bypass this and add support to the library if the developer of the library didn't updated his library yet ?

4   the author stated the tag of ios6 but if you know the answer it will probably be the same or very close to adding support to library to support armv7 so the answer might not be violating NDA. having the same problem –  user513790  Sep 13 at 8:23   If you have the source to the library, it's pretty easy. In my case, I'm using OpenEars (for TTS and voice command,) and all I had to do was download the source, open up the Xcode file included with the source code, Xcode automatically updated the build settings, I hit Product -> Build and bam, I had a nifty new OpenEars.framework with support for the new armv7s architecture. If you don't have the source code, then no, I don't think there's anyway to do this, you'll just have to wait for the author to release a new version. –  ArtOfWarfare  14 hours ago feedback

If you want to remove the support for any architecture, e.g. armv7s in your case, try this: Project -> Build Settings -> remove the architecture from "valid architectures" You can use this as a temporary solution until the library has been updated. You have to remove the architecture from your main project,not from the library. Alternatively, you can set the flag for your debug configuration's "Build Active Architecture Only" to Yes. Leave the release configuration's "Build Active Architecture Only" to No, just so you'll get a reminder before releasing that you aught to upgrade any 3rd party libraries you're using. share | improve this answer edited  yesterday ArtOfWarfare 77 10 answered  Sep 13 at 9:10 Nicholas 911 3 7

nice solution but is there a way to add support without compiling the library ? –  user513790  Sep 13 at 9:33 7   you don't have to recompile the library. you can remove this flag from the project that is using the library. –  Nicholas  Sep 13 at 9:57 4   It will work, since old apps that have not been compiled with armv7s support have to run as well. But you will loose some specific optimizations. This should be a temporary workaround anyway. –  Nicholas  Sep 13 at 12:46 2   Dropbox framework has been updated for this issue see forums.dropbox.com/topic.php?id=90014 –  railwayparade  Sep 17 at 6:31 1   Had to do this for TestFlight SDK. Thanks! –  Fogmeister  Sep 17 at 9:34 show 11 more comments feedback

I just posted a fix here that would also apply in this case - basically, you do a hex find-and-replace in your external library to make it think that it's ARMv7s code. You should be able to use lipo to break it into 3 static libraries, duplicate / modify the ARMv7 one, then use lipo again to assemble a new library for all 4 architectures. share | improve this answer answered  Sep 13 at 18:16 Ertebolle 1,038 4 13

Flurry Support for iPhone 5 (ARMv7s) As I mentioned in yesterday’s post, Flurry started working on a version of the iOS SDK to support the ARMv7s processor in the new iPhone 5 immediately after the announcement on Wednesday. I am happy to tell you that the work is done and the SDK is now available on the site. share | improve this answer answered  Sep 15 at 18:52 RAZ 148 3
