After following these steps to set up an iphone project with CoverStory, my build fails with two linker errors.
Undefined symbols:
"_vproc_transaction_end", referenced from:
_gcov_exit in libgcov.a(_gcov.o)
_vproc_transaction_end$non_lazy_ptr in libgcov.a(_gcov.o)
(maybe you meant: _vproc_transaction_end$non_lazy_ptr)
"_vproc_transaction_begin", referenced from:
___gcov_init in libgcov.a(_gcov.o)
_vproc_transaction_begin$non_lazy_ptr in libgcov.a(_gcov.o)
(maybe you meant: _vproc_transaction_begin$non_lazy_ptr)
ld: symbol(s) not found
collect2: ld returned 1 exit status
I'm using Xcode 3.2, GCC 4.2 on Snow Leopard. Any ideas what I'm missing?
Here's how to get gcov running with Xcode 3.2.2, GCC 4.2 on Snow Leopard:
http://code.google.com/p/coverstory/wiki/SnowLeopardGCov
Did you add "-lgcov" to Other Linker Flags as the Web page directs?
What is the value of the MACOSX_DEPLOYMENT_TARGET setting? This page and this page suggests the value needs to be set to 10.6.

I am facing linker error after upgrading Xcode from 7.3 to 8.3.1,
below is the error coming at the time of project build:
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$__TtCC13Test11AppDelegate12loggedinUser", referenced from:
objc-class-ref in UIView+Toast.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Architecture Settings in Build Setting:
Compile Sources:
Please help. Thanks in advance.
Check your TestAppDelegate class, especially property loggedinUser. There should be some clues.
This may be a problem, that the target you are compiling is using the UIView+Toast file, which requires the TestAppDelegate to also be compiled.
Check your project settings -> build phases -> compile sources and check if any entries are colored red (missing under the path) or are just not there, and readd them.
I am using z bar SDK in x code 5 when i am archiving its getting following errors

It seems you missed the one of the frameworks - Core Media.
Check the following integration link for ZBar sdk.

Remove armv7s arm64 Architectures only use the armv7 and solve your problem.
Project -> Build Settings -> Architectures -> Delete armv7s arm64
Importing a header and do not linking against the correct library will cause that error. Check you have imported the correct libraries. A more complete answer can be found here

I am trying to use the AdMob in my test application when I rum my application i am getting the following error as shown below.
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_ASIdentifierManager", referenced from:
objc-class-ref in libGoogleAdMobAds.a(GADIdentifierUtilities.o)
"_OBJC_CLASS_$_SKStoreProductViewController", referenced from:

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I googled around this errors and everyone telling to add the AdSupport.framework. But when I try to add that framework in my Xcode4.1 and Xcode4.4 there is no AdSupport.framework is not missing. Where can I get it and how to add that framework.
AdSupport.framework available only in iOS6+, so you won't be able to find it in XCode version prior to 4.5
UPD:
According to AdMob 6.2.0 changelog:
Required to use Xcode 4.5 and build against iOS 6. The minimum deployment is iOS 4.3.
I am developing a application in iOS which compile on iOS 5.0 perfectly .But Unable to compile on xCode on iOS 5.1 .The fallowing problem is arising.
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_SenTestCase", referenced from:
_OBJC_CLASS_$_RFAPITests in RFAPITests.o
"_OBJC_METACLASS_$_SenTestCase", referenced from:
_OBJC_METACLASS_$_RFAPITests in RFAPITests.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
This is a linker problem. The code or library that defines SenTestCase needs to be added to the appropriate compile or link phase for your target depending on whether it's in source or binary form.
I have downloaded the SDL Library, i created an Xcode project, but when i try to build the xcode return this error:
Undefined symbols for architecture i386:

"_SDL_CreateCond", referenced from:
-[testViewController packet_queue_init:] in testViewController.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status
how can i fix it??
thanks
Keeps happening to me randomly too. Assuming you're still using your project, just try to toggle the options for the following settings :
Build active architecture only (DEBUG is usually YES, RELEASE is usually NO).
SDK : Latest
Build target: iPhone OS 4.0 (Or whatever your min supported OS is)
