Xcode 4 Final - "armv6 armv7" issue while linking with armv6 libs
Until xcode 4 final (I was using 3.latest and 4 GM for the time it was available) this didn't happen. When I upgraded to xcode 4 final version, I started getting a linking error while trying to link the armv7 version with my non armv7 library (my project is set with the default Standard armv6 armv7 valid architectures):
ld: warning: ignoring file ../bin/iOS static/arm/libssl.a, file was built for archive which is not the architecture being linked (armv7)
ld: warning: ignoring file ../bin/iOS static/arm/libcrypto.a, file was built for archive which is not the architecture being linked (armv7)
Undefined symbols for architecture armv7: -- list of symbols --
The armv6 version compiles just fine, but the overall compilation process fails with 77 link errors.
I understand this is the expected behavior, it wont link towards armv7 with an armv6 lib. The fix is setting my project to armv6 only. My question here is: why was this working in the previous versions of xcode?
If I set to armv6 only, I start to get this warning:
Check dependencies
[BWARN]warning: all apps should include an armv7 architecture (current ARCHS = "armv6").
I don't like seeing warnings :-) Anybody having similar issues?
Thanks,
Fernando
Answer
I just turned the Build active architecture only to Yes in the Project -> Build Setting -> Architectures tab.
