“Warning: iPhone apps should include an armv6 arch

Question

It's been a while since I've had to adjust project build settings. After upgrading to a recent SDK I'm having trouble building my ad hoc distribution configuration.

Build generates this warning and error:

warning: iPhone apps should include an armv6 architecture (current ARCHS = "armv7")

iPhone/iPod Touch: application executable is missing a required architecture. At least one of the following architecture(s) must be present: armv6 (-19033)

However in my project I thought I had things set correctly:

• Architectures is: Standard (armv6 armv7)
• Base SDK: Latest iOS (currently set to iOS 4.2)
• Valid Architectures: armv6 armv7

I have cleaned all targets.

I appreciate any tips.

Answer 1

Using Xcode 4.2 on Snow Leopard, I used the following settings to build an app that worked on both armv6 (Iphone 3G and lower) AND armv7 (everything newer than 3G including 3GS).

architectures: armv6 and armv7 (removed $(ARCHS_STANDARD_32_BIT))
build active architecture only: no
required device capabilities: armv6

do not put armv7 in required device capabilities if you want the app to run on 3G and lower as well.

Answer 2

I had this problem even after following the accepted answer and found the following to work:

In your Info.plist, add an entry for Required Device Capabilities. This should be an array and will have two entries.

• Item 0 : armv6
• Item 1 : armv7

It will look like this:

Answer 3

Quite a painful problem for me too. Just spent about an hour trying to build and re-build - no joy. In the end I had to do this:

1. Upgrade the base SDK to the latest ( in my case iOS 5 )
2. Restart xCode
3. Clean & Build
4. It worked!

I guess it's a bunch of jargon about arm6 , arm7 as it looked like my project was valid for both, at least the settings seemed to say so ) , my guess is this is a cynical way to bamboozle us with the technicalities, which we don't understand, so we just take the easy option and target the latest iOS ( good for Apple with more people being up-to-date ) ....

Answer 4

I had to be sure to change these settings in both the Target and Project settings on xCode 4.3.2 after doing that and setting it to build for both armv6 and armv7 everywhere I was able to submit my app.

For safe measure I also exited xCode between making the changes and doing a clean, build, archive cycle.

Answer 5

Try changing your deployment target to something higher than an armv6 processor. The settings for xCode are referencing the operating system level, for instance: iOS version#{3.1, 3.2, 4.0, 4.1, 4.2, 4.3, 5.0, 5.1}

(i)You can set this in the build settings tab or the summary tab. Start at the top left of the window in the Project Navigator, with all the files listed in it. Click the top-most one which has a blue icon.

(ii)If you are planning on using the programmable shader line circuitry, which is accessed and controlled through openGL ES 2.0 API, then you should set your "Deployment Version" to about 4.3, which I believe is only available on devices such as the 3GS or newer. xCode is reporting that iOS 4.2.5 or higher is needed run armv7 code. And once again, this processor, I believe, started with the 3GS.* iOS 4.3 seems to be the choice for me, for now.
