I'm creating a static library with some class files, and the library is creating well but if I install to library to another new Xcode project it showing error and the error is as follows ,
ld: warning: ignoring file /Users/rajesh/Desktop/Quntiles/01-03-2013/ConnectionExample-1/libAVTEmployee.a, file was built for archive which is not the architecture being linked (armv7s): /Users/rajesh/Desktop/Quntiles/01-03-2013/ConnectionExample-1/libAVTEmployee.a
Undefined symbols for architecture armv7s:

ld: symbol(s) not found for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Can any one please help me, how can I fix this issue so that I can use the my static library in my new project ,
I'm using Xcode 4.6 version.
Thanks in advance.
Probably your static library was created or compiled using an older version of XCode that didn't support armv7s architecture. Open the static library project and make sure that Architectures contains armv7 and armv7s architectures and Build Active Architectures Only is set to No under Build Settings.

I'm quite new to Xcode and Iphone development and ran into the following problem:
I opened a new project and added *.h and a *.a files (which I recived from a certain device vendor).
I get the following warning:
ld: warning: ignoring file /Users/udi/Desktop/Xcode/Xcode Projects/Scosche/libmyTrekSDK_armv7.a, missing required architecture i386 in file /Users/udi/Desktop/Xcode/Xcode Projects/Scosche/libmyTrekSDK_armv7.a (2 slices)
If I ignore the warning, and try to instanciate the class that is given to me in the header file, I get these errors:
ld: warning: ignoring file [Path/FileName.a], missing required architecture i386 in file [Path/FileName.a] (2 slices)
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_HRMonitor", referenced from:
objc-class-ref in ViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
I've checked the Framework Search Pathes (as mantioned in many other posts) and it clear.
More info:
I'm Using Xcode 4.6.1
The files are currently located at project's root folder.
I'm using a Single View Application tamplate.
Appreciate any help
This warning means that you're trying to use library made for Device (ARM) with your Simulator (i386).
You can use this terminal command to create a universal library:
lipo -create lib_arm.a lib_i386.a -output lib_universal.a
More info about lipo command here.
Change your target's "Build Settings > Build Active Architectures Only" to "No"
This is doing the same thing as Dmitry Zhukov's answer but doing it thru Xcode instead of going around its back.
If you are working with a 3rd party code, keep in mind that some SDKs may not work on the simulator. The same build error I have encountered vanished, when I ran the project on the device.
I am trying to integrate admob in my ios application but I am getting following errors when I add sdk and build it.

I have included all required framework including SystemConfiguration, CFNetwork etc.
Update
I am getting this error when I build in simulator but not when I build with device. is it sdk issue? I am using simulator 5.1.
Make sure that the frameworks that you added are correctly linked under the "Link Binary With Libraries" section of your Build Settings. Also, look at "Compile Sources" under "Build Phases" to make sure all of the relevant files you want to compile are there.
So I have an iPhone static library that I am trying to build. I've got the script that was used in this question (http://stackoverflow.com/questions/3520977/build-fat-static-library-device-simulator-using-xcode-and-sdk-4), but the issue I've hit is that I'm seemingly still unable to successfully build the static library for the simulator. When I build in the static library project, I get the follow warnings:
warning: no rule to process file '$(PROJECT_DIR)/GDInAppStore/GDInAppStore.m' of type sourcecode.c.objc for architecture i386
warning: no rule to process file '$(PROJECT_DIR)/GDInAppStore/SKProduct+priceAsString.m' of type sourcecode.c.objc for architecture i386
warning: no rule to process file '$(PROJECT_DIR)/GDInAppStore/VerificationControllerPBK.m' of type sourcecode.c.objc for architecture i386
I believe this issue is causing the problem that is leading to the universal library I get from the build script causing this error in my other project
ld: warning: ignoring file /Users/abotkin/Projects/Static Libraries/GDInAppStore/libGDInAppStore.a, missing required architecture i386 in file
"_OBJC_CLASS_$_GDInAppStore", referenced from:
objc-class-ref in SubscribeNowInAppController.o
ld: symbol(s) not found for architecture i386
I'm using Xcode 4.3.2 and have set the flags in the static library Xcode project so that i386 is included in the Architecture and Valid Architectures. Any tips?
Make sure you are building for the simulator if you are compiling for i386. Basically, your arch parameter has to match your sdk parameter. i.e.
xcodebuild -project proj.xcodeproj -arch armv64 -sdk iphoneos8.1 build
and
xcodebuild -project proj.xcodeproj -arch i386 -sdk iphonesimulator8.1 build
I was able to do a workaround this issue by using Karl's iOS Universal Framework that he mentioned in the other topic here https://stackoverflow.com/a/5721978/497718
That said, if anyone could point me into what I may have been doing wrong in using the script in that same topic, I'd love to learn how to do it the right way.
With Xcode 6, Apple has added iOS framework support to their build tools.
Using Apple's framework target for all new projects, as it is less hacky and is supported by Apple themselves.
I am trying to build a simple torch application for iOS 5 as described in http://developer.apple.com/library/mac/releasenotes/AudioVideo/RN-AVFoundation/_index.html#//apple_ref/doc/uid/TP40010717-CH1-DontLinkElementID_17 but i am getting "Apple Match-O Linker Error:

objc-class-ref in FirstViewController.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Any help appreciated
Anybody ?
Additionally: it only happens when running the project, no errors if i just clean & Build, and the code completion detects the library.
Thanks
You might need to link your project with the AVFoundation framework first.
If you're already doing that, make sure you're building for armv7 and not just armv6.
Check it in your project settings > Target > Build Settings > Architecture
As simple as this:
Linker errors like this indicate that a symbol is missing when the app is being linked. Most system symbols like these, come from system frameworks. So, I was missing a framework in my project that contains AVCaptureDevice and AVMediaTypeVideo.
To solve it, i just added the AVFoundation framework following this tutorial: http://www.thinketg.com/Company/Blogs/11-03-20/Xcode_4_Tips_Adding_frameworks_to_your_project.aspx
Now it runs !
i get this error when i am trying to use my compiled static library in my iphone aplication. I have no frigging idea what's wrong.
ld: warning: ignoring file /Users/rw/Library/Developer/Xcode/DerivedData/MSTicketingSaaS-gkznscznevvifjesoapzgwycbces/Build/Products/Debug-iphoneos/libMylib.a, file was built for archive which is not the architecture being linked (armv6)
Undefined symbols for architecture armv6:
"_OBJC_CLASS_$_AppData", referenced from:
It worked before upgrading to Xcode 4.0.2
I added the i386 architecture and now it compiles for the simulator but NOT for the device.
Check with lipo which is the architecture your lib has been built for:
lipo -info <path_to_lib>
If it does not contain "arm6" then you should go back to the library project and build it for the proper architecture. If this does not help, please, give more detail about the structure of your project(s).
