I have tried to add a testunit target to my project but failed enourmously.
My testunit requires libxml2.dylib (actually libxml2.2.dylib) and of course sentestingunit.framework.
I add the libxml2.dylib to the FRAMEWORK_SEARCH_PATHS in build settings
$(inherited) "$(SYSTEM_APPS_DIR)/Xcode.app/Contents/Developer/Library/Frameworks"
Then I add the sentestingunit.framework in the build phase -> link binary with libraries.
I have my app (called vindfyrar) as a target dependencies.
Now the the build of my testing target start to scream all the stuff below;
Any one got an idea what I have done wrong?
i386? Why?
Beleive me on this one, I have done my homework, i e googled and try every option in the build settings that could possible be wrong... No success.
XCode 4.6 on Lion 10.7.5
Kind regards,
Jan Gifvars

You're linking against the iPhoneOS SDKs (where all the binaries are built for architecture arm) but you're building an iPhone Simulator program (i386). Your project is linking against the wrong SDK.
I have solved the problem by adding these setting and values.
For Test Host it's $(BUNDLE_LOADER)
For Bundle Loader it's $(BUILT_PRODUCTS_DIR)/ApplicationName.app/ApplicationProductName
If you want more details log in to apple.developer and search for
"Test case give Apple Mach-O Linker Error"
Thanks everyone for your time!

As far as I can see you have already solved problem with Bitcode, so my answer only about last error messages:
ld: warning: ignoring file /Users/anurajennai/Desktop/myApps/unziped/cdm_player_xcode_template/oemcrypto_tfit_ios_dylib/release/oemcrypto_tfit2-eit_release_dylib.framework/oemcrypto_tfit2-eit_release_dylib, missing required architecture i386 in file
means that lib doesn't have i386 arch (can't be used on simulator) try build for iOS device
second one:
ld: embedded dylibs/frameworks are only supported on iOS 8.0 and later
but I see that in your project:
export IPHONEOS_DEPLOYMENT_TARGET=7.0
deployment target set to 7.0 so you should decide something with it
Compiling my main target (not a test target like here) yields this error:

The Missing Link:
This error is almost always produced by not having the binary linked to the library (In this case it would be the Crashlytics.framework):
Trying to build the target MyApp (which includes headers with #import <Crashlytics/Crashlytics.h> will produce the error:
ld: warning: Auto-Linking supplied
'../../Crashlytics.framework/Crashlytics', framework linker option at
../../Crashlytics.framework/Crashlytics is not a dylib
Link the Framework:
Fortunately, it should be easy to fix the problem simply by dragging the Crashlytics.framework from the Frameworks folder in the project navigator into the list of Link Binary With Libraries or by using the +.
Make sure you have your App selected/highlighted under Targets while doing this process.
I had the same issue but my reason was different.
Error Output

clang: error: linker command failed with exit code 1 (use -v to see invocation)
Reason
My target was overriding the OTHER_LDFLAGS.
Solution
Changed the OTHER_LDFLAGS to just inherit the Linker Flags. Basically, changed it to $(inherited)
I followed all steps provided by #i'L'i but I was not able to find Crashlytics.framework and Fabric.framework file in build phases.
So this helped me.
Step 1: Follow all the steps given Here.
Step 2: Now when you are unable to find Crashlytics.framework and Fabric.framework files in Link Binary With Libraries by clicking + do following.
2.1: Click on + button in Link Binary With Libraries.
2.2: Click on Add Other... button.
2.3: Now chose Crashlytic.framework and Fabric.framework from Pod folder - if using cocoapods, else choose both file from where you have downloaded it.
Step 3: Build Succeeded, Enjoy. :)
For future reference, this can also happen if you link your test files to your app target.
For example:
https://github.com/realm/realm-cocoa/issues/1661
I had the same problem. Maybe I messed up the initial fabric install but once I added Fabric.framework to the list of frameworks (should be in the root folder of your app by default) everything worked.
Conversely to what I'L'I and user3517250 mention, the problem might also be that you have #import statements that shouldn't be there.
Xcode does infer the frameworks to link against from the #import statements. If you import a framework that you don't link against, then you get this warning.
I cannot compile my project for the simulator .
I get Apple Mach-O-Linker error.I cant understand how to solve the issues.I am using xcode 5.0.1.
Please help me any body.
Thanks in advance.

XCTest.framework needs to be linked only to the unit test target in your project. It should not be added to the UI application target.
What I have found is when adding XCTest.framework Xcode adds extra \ to Framework Search Paths
\"$(SDKROOT)/Developer/Library/Frameworks\"
\"$(DEVELOPER_LIBRARY_DIR)/Frameworks\"
$(DEVELOPER_FRAMEWORKS_DIR)
This causes linker issue,
ld: building for iOS Simulator, but linking against dylib built for MacOSX file '/Applications/Xcode.app/Contents/Developer/Library/Frameworks/XCTest.framework/XCTest' for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
To resolve this issue in XCode 5.1 goto the main ProjectWindow, Tab Build Settings -> Section Search Path -> Framework Search Paths and edit to remove \ appearing the paths.
Hope that helps!
Deleting the test target and creating a new one and then copying the tests over can fix this.
I suggest you to use xcode 5.02 stable version and then hopefully these Mac-O Linker errors will be resolved.same problems I am facing too before installing xcode 5.02.

I got JSON framework files from downloaded example. The examples are working perfectly, but my project showing above errors.
Symbol(s) not found for architecture i386
The above error occurs in the following situation:
You were trying to run your application in the iPhone/iPad Simulator
The library was only built to run on the physical devices, and does not support being run in the Simulator.
To resolve this, you either need to add i386 to the Valid Architectures of the SBJSON library build target, or test your application using a physical device.
You didn't add the SBJSON.m file to your target. Check the properties panel for this file, and there should be a checkbox indicating which target it is assigned to. You may have simply forgotten to copy SBJSON.m into your project at all.
go to Projectapp -> Buildphases -> compileSources
here to add all .m files of JSON with + icon. problem will be resolved
I have no idea how to debug this, and I've been banging my head against the wall for hours. Here is the error I got:

Any help is really appreciated. I would normally spend more time working on my own to solve the problem, but I really have no idea where to start.
If you are building against Simulator then you explicitly need to add i386 as an valid architecture. Also check under platform you have "iphonesimulator". Just click on your project file and it will reveal Build settings in the right side editor. You will find these settings there. Hope it helps.
It is saying that there is a missing 32 bit Intel architecture in the relevant libraries.
I would ask why you are persisting with GCC 4.2 when LLVM 2.0 is the default compiler now and gcc development has been shut down (at Apple)
Have a go at switching to LLVM 2.1 and see if the problem remains.
You really need to be asking about this bug on the Apple Dev forums if it's important to you to use GCC as iOS 5 and XCode 4.2 are NDA
You have forgot to add any library.try to add a directory that what you have missed.It resolve this issue.
