I am trying to build iOS app from flutter and getting below errors.
Read https://github.com/flutter/flutter/issues/17749
Check Configuration here
In Short:
Flutter frameworks contain armv7, arm64, and x86_64 slices but NOT i386. When you run in the simulator, Xcode silently maps armv7 to i386 simulator and arm64 to the x86_64 simulator. ONLY_ACTIVE_ARCH=YES build setting builds only for the architecture of the device or simulator you are targeting. Xcode docs:
If enabled, only the active architecture is built. This setting will be ignored when building with a run destination which does not define a specific architecture, such as a 'Generic Device' run destination.
So if you are targeting a real recent iOS device, it will build arm64, and if you target a recent simulator, it will build x86_64. ONLY_ACTIVE_ARCH=YES is the default for the Debug build configuration for new Xcode projects.
If you have ONLY_ACTIVE_ARCH=NO and target a real device, it will build armv7 and arm64 and will succeed. If you target a simulator, it will try to build i386 and x86_64 and fail with this error because i386 is missing. ONLY_ACTIVE_ARCH=NO is the default for Release build configurations for new Xcode projects because you need to publish all valid architectures to the App Store.
Flutter is not supported in Release on the simulator.
I have been developing my app using Simulator and an old iPhone 4S.
I tried to run the app on an iPad Mini 3, but I get this warning:
file was built for armv7 which is not the architecture being linked (arm64)
any idea on how to fix it?
EDIT:
The error was related to the UnitTest target.
I deleted such target (as I am not doing unit tests) and the warning disappeared.
For each target that needs to be built:
Go to Build Settings > Architectures
Set to $(ARCHS_STANDARD)
Go to Build Settings > Valid Architectures
Set to arm64, armv7, armv7s
Perform a Product > Clean just to be safe and Product > Build your project for the iPad Mini 3.
I have too many warnings on building for archive. And no errors on building for x32 devices or simulator.
How can I disable building archive for arm64 CPU on Xcode?
I've tried to set Architectures and Valid Architectures on project's Build Settings to armv7 armv7s or $(ARCHS_STANDARD_32_BIT) and Build Active Architecture Only to YES but with no success.
Try Build Active Architecture Only to YES in Build Settings
Also set $(ARCHS_STANDARD_32_BIT) or armv7 and armv7s in Architectures and remove the $(ARCHS_STANDARD).
Do it in every single place and on all dependent projects in your workspace
After updating to Xcode 5.1, I can no longer build my project for the 64-bit simulator, receiving this error:
No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=i386).
These are my target build settings:
I tried changing "Build Active Architecture" to No, as well as adding "i386" to the "Valid Architectures", unfortunately neither worked.
Thanks for any suggestions!
What you need to do is just set the ONLY_ACTIVE_ARCH to NO (at least works for me). Below is a screenshot for it:
EDIT:
As far as I know (please point it out if there's something wrong, thanks), if you set ONLY_ACTIVE_ARCH to YES, it means the Xcode will only build for the active architecture (which refers to the device that's active in Xcode currently). Seems Xcode's default setting is set Debug to YES, so it won't build binaries for other architectures when you only want to build for a special device that connected to your Mac.
The reason failed to build might be that, the project does not support the architecture of the device you connected. So the best solution is to add the right architecture for your device. Below is a list for architectures & the devices that support:
ARMv8/ARM64: iPhone 6, iPhone 5s, iPad Air, Retina iPad Mini
ARMv7s: iPhone 5, iPhone 5c, iPad 4
ARMv7: iPhone 3GS, iPhone 4, iPhone 4S, iPod 3G/4G/5G, iPad, iPad 2, iPad 3, iPad Mini
ARMv6: iPhone, iPhone 3G, iPod 1G/2G
So why "set the ONLY_ACTIVE_ARCH to NO" works? Because the device can still run the binary that built for all architectures you added (pass the build), but will lose some performance. This's just a quick solution, but not best.
Note: The more architectures you added, the bigger the binary will be generated. So it's good to choose right architectures for your project. ;)
I had the same error message after upgrading to XCode 5.1. Are you using CocoaPods? If so, this should fix the problem:
Delete the "Pods" project from the workspace in the left pane of Xcode and close Xcode.
Run "pod install" from the command line to recreate the "Pods" project.
Re-open Xcode and make sure "Build Active Architecture Only" is set to "No" in the build settings of both the "Pods" project and your own project.
Clean and build.
Add arm64 to the target's valid architectures. Looks like it adds x86-64 architecture to simulator valid architectures as well.
If you are using CocoaPods, the most likely problem is because your Pods project Build Settings for Build Active Architecture Only is set to Yes for Debug.
The solution is simple. Change it to No.
Similarly, change to No for your application project.
I had similar issue. Got it solved by changing "Architecture" to "$(ARCHS_STANDARD_32_BIT)" in Build Settings for Project.
Now, you have to select Standard architectures (armv7, arm64) - $(ARCHS_STANDARD) since apple recommends apps to be build on 64-bit architecture. Click : Apple document
Add:
Architectures: $(ARCHS_STANDARD_INCLUDING_64_BIT)
Valid architectures: arm64 armv7 armv7s
Just in case, for anyone still encountering the issue despite following the above, check that the simulator you are running is also the supported one. I had mine specified to arm7 and arm7s but was trying to run the app on a 64 bit simulator.
To avoid having "pod install" reset only_active_arch for debug each time it's run, you can add the following to your pod file
# Append to your Podfile
post_install do |installer_representation|
installer_representation.project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['ONLY_ACTIVE_ARCH'] = 'NO'
end
end
end
Just add arm64 in valid architecture.i hope it will work for you.
My problem was that the Pods project was targeting OS X, despite my Podfile having platform :ios. I'm using cocoapods 0.35.0.rc2.
To fix it, select the Pods project in the project navigator, and check that the Pods PROJECT node (mind you, not the Pods target) is targeting iOS. That is, the architectures build settings should be:
Architectures: $(ARCHS_STANDARD)
Base SDK: iOS 8.1
Supported Platforms: iOS
Valid architectures: $(ARCHS_STANDARD)
I also wanted to build all architectures, so I added the following to the Podfile:
post_install do | installer |
installer.project.build_configurations.each do |config|
config.build_settings['ONLY_ACTIVE_ARCH'] = 'NO'
end
end
I had to add the following i386 and x86_64 to Valid Architectures. I'm running Xcode 7.2 and targeting iOS 8+. I already had armv7, armv7s and arm64 in there and that was working in Xcode 6.4.
I faced the same problem when running my app on iPad using xcode 5.1. It got resolved by removing armv7s from 'valid architectures' and setting the 'build active architectures only' value to No. Both these fields can be found in your app->targets->build settings->architectures.
I arrived at this question due to a problem with command line build for simulator in Xcode 7.2. In case anyone else gets here with the same issue, I will share the solution I found:
Apparently there is a bug in Xcode 7.2 that causes xcodebuild to fail when trying to build for simulator. The solution is to specify the option "-destination", e.g:
xcodebuild -project TestBuildCmd.xcodeproj -scheme TestBuildCmd -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 6' build
Update
The above example command will build a binary including the graphics for iPhone 6 only. If the binary is run on other simulators, the iPhone 6 graphics is scaled to the platform. A better workaround which contains all graphics for all platforms is to specify the parameter PLATFORM_NAME=iphonesimulator, for example:
xcodebuild -project TestBuildCmd.xcodeproj -scheme TestBuildCmd -sdk iphonesimulator -arch i386 PLATFORM_NAME=iphonesimulator build
Try removing all previous architectures (i.e. remove the ARCHS_STANDARD setting) at the same time as you add i386 to the Architectures. This should change the active architecture to i386. I encountered a similar issue when I tried to build for armv7 by default, but it kept trying to build for arm64. I changed ARCHS_STANDARD to ARCHS_STANDARD_32_BIT, and this changed the active architecture chosen.
In acrhiecture - sometimes to support 6.0 and 7.0 , we exlude arm64
In architectures - > acrchitecture - select standard architecture arm64 armv7 armv7s.
Just below in Valid acrchitecture make user arm64 armv7 armv7s is included.
This worked for me.
I solved this problem using #Kjuly's answer and the specific line:
"The reason failed to build might be that, the project does not support the architecture of the device you connected."
With Xcode loaded it automatically set my iPad app to iPad Air
This caused the dependancy analysis error.
Changing the device type immediately solved the issue:
I don't know why this works but this is a very quick answer which saved me a lot of fiddling around in the background and instantly got the app working to test. I would never have thought that this could be a thing and something so simple would fix it but in this case it did.
I found that it was necessary to enter the architecture names by hand:
I don't know why this was necessary, i.e. why these values were not inherited from Xcode itself. But as soon as I did this, the problem went away.
In Valid architectures: Select each entry (release, debug) and build and press backspace. It should work
Building my iOS App in Xcode 4.5 results in Dependency Analysis Warnings for every source file:
warning: no rule to process file of type sourcecode.c.objc for architecture armv6
This eventually results in a missing binary. Any ideas what's wrong here?
Build settings: armv6 armv7 Valid Architectures and iOS 4.3 Deployment Target.
Xcode 4.5 does not support building armv6 binaries anymore.
Set Valid Architectures to armv7.
