First of all there is a lot of question Asked how to solve that compilation Error that seems happening when importing lib/files. Can anyone explain what does it mean by "Undefined symbols for architecture armv7" first of all. I imported files for ntp client for iso (http://code.google.com/p/ios-ntp/source/checkout) which worked in its own Xcode project but when i moved to my project and it failed with the following Error and warnings . Any idea ?

You shouldn't have .h files among .c files to be compiled.
Go to "Build Phases" tab of your target. Then check the "Compile Sources" section and remove the .h files.

I tried adding the libsqlite3.dylib library but I can't find it on my system. Is it required? If so, how do I find it?
It looks like libsqlite3.tbd is the new libsqlite3.dylib. I added it and everything worked.
Go to the Build Phases tab. Expand the "Link Binary with Libraries" section. Click on the + icon. Search for "sqlite". Add the library
I am getting below error. It was working fine and I don't have any idea about what caused this issue.

I tried removing and adding CrashReporter from and to project.
Select your project, go to Build Settings and have a look at the Architectures. You should delete arm64 from the Architectures and also from Valid Architectures and Build the app again.
I have run chart boost demo which have been provided at chart boost site.
It shows error like below,
ld: warning: ignoring file /Users/jeganselvaraj/Unity3D/SlotMachine_IOS/Libraries/libChartboost.a, missing required architecture i386 in file /Users/jeganselvaraj/Unity3D/SlotMachine_IOS/Libraries/libChartboost.a (2 slices)

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
What can I do for this issue?
Seems like there is no libChartboost.a in your Xcode project's Libraries folder.
You need to ensure that file libChartboost.a is in directory Assets/Plugins/iOS. All files from Assets/Plugins/iOS are copied to the Xcode project automatically during Unity's build process. Note that subdirectories within Assets/Plugins/iOS are not considered.
I have an error like this

How can you solve this problem? Please help me.
Find the file ViewController.m in your project and select it.
Use the properties inspector (Apple-Option-1) to ensure that it's added to your target membership whatever that target may be. It will need have a tick next to the target.
