Compile library for armv7s-cputype (12) and cpusubtype (11)

Http://stackoverflow.com/questions/12549489/compile-library-for-armv7s-cputype-12-and-cpusubtype-11

I'm a developer of a third party library and I 'd like to recompile my library for armv7s, but I seem to have issues.

I updated xcode to 4.5. I updated the project and the related targets to have valid ubunturesarmv7
armv7s.

However, when I runfileOrlipo
-info, It lists

• I386
• Armv7
• (Cputype (12) cpusubtype (11 ))

No armv7s. Am I missing something?

Use xcode's lipo:

xcrun -sdk iphoneos lipo

Apparently,(cputype
(12) cpusubtype (11))Is another nomenclature for armv7s.

You can refer more here: http://www.galloway.me.uk/2012/09/hacking-up-an-armv7s-library/

The above blog also describes a method for making some libraries armv7s build compatible. The description of above is near the end of the article where he explains about the output fromfileCommand.

To quote a part of it:

Inside this header (called a Mach-O header) is a field for the CPU type and the CPU subtype. arm is CPU Type 12, armv7 is CPU subtype 9 and armv7s is CPU subtype 11.
