File is universal three slices but it does not contain a n ARMv7-s slice error for static libraries on iOS anyway to bypass

Question

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 any way to bypass this and add support to the library if the developer of the library hasn t updated their library yet

use menu Project -  Build Settings -    then remove armv7s from the valid architectures   If standard has been chosen then delete that and then add armv7

In my case  I was linking to a third-party library that was a bit old  developed for iOS 6  on XCode 5   iOS 7    Therefore  I had to update the third-party library  do a Clean and Build  and it now builds successfully

In case this happens to someone  I built my own library to use with a third party code  While I was building it to deliver  I accidentally left my iPhone 4S plugged in  and so Xcode built my library only for the plugged architecture instead of following the project settings  Remove any plugged in devices and rebuilt the library  link it  and you should be all right   Hope it helps

If you want to remove the support for any architecture  for example  ARMv7-s in your case  use menu 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 ought to upgrade any third-party libraries you re using

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

[ios] File is universal (three slices), but it does not contain a(n) ARMv7-s slice error for static libraries on iOS, anyway to bypass?
