I have imported some files which is required for this functionality but when i try to run the app in simulator the errors listed below occurs. I can't understand which type of errors are these. so plz help me solve this problem.

You didn't include the libz.tbd where those functions are. Select the project node, select your target, go to the Build Phases tab, expand "Link Binaries With Libraries", add libz.dylib, and try again.
Add libz.dylib to your framework, it will work..
I faced the same issue, and thanks to Jano, it was resolved after I added the Libz.dylib to the project.

I tried running a basic opengl program from this link. I can run it successfully. Now I need some functionalities of opencv to be added in this.
So I added opencv framework from this link.
After adding the framework I changed the files to .mm and its compiling good. The problem comes when I add "cv::Mat Variable". I get the below error. What would be the reason for this?

This Solves my problem. To add add opencv library file
AVFoundation.framework
ImageIO.framework
libz.dylib
should be added. And this link explains clearly about this. http://aptogo.co.uk/2011/09/opencv-framework-for-ios/

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
It is difficult to analyse such questions without a project at your eyes. But as they are linker errors and you seem to use one of the latest Xcodes and WallViewController is not standard UIKit class (as far as i know(there is no 'UI' prefix)), i guess that you included the files improperly.
Try to delete references to the WallViewController files and add them again into the project by right clicking the group where you want to put them and then "add files..." (my xcode doesn't like dragging for some unknown reason).
Pls have look at link.
Select project and goto build phase and add the missing file "WallViewController.m" to compile source.
I'm trying to create application that sends email

keep in mind that I'm using Xcode 4.3 ,
what shall I do to solve this??
After adding the CFNetwork framework and SystemConfiguration framework ,
the number of errors decreased from 6 to 4 and it is now

This error message means that those classes search some objects in a framework that you haven't linked to your project. Here you can found what framework do you need: the CFNetwork framework.
I hope it helps!
EDIT
The other 4 errors might be caused by the incorrect importation of the SKPSMT classes. If that classes are downloaded as a library, you'll also need to link your app with that library.
Try adding the following linker flags:
OTHER_LDFLAGS = -lz -lxml2 -ltidy -ObjC

How to solve this errors, any idea ?
Thanks In Advance !!
The logs seem to indicate that the problem is coming from the libz.1.2.3.dylib framework.
What iOS SDK are you using (and which Xcode version) ?
In your project, click on your target and go to the Build Phases tab, then "Link binary with libraries" section.
Try removing the libz.1.2.3 framework and then re-adding the libz.1.2.5 (click on the little "+" at the bottom of the window and select libz.1.2.5 from the list).
EDIT:
As stated by Abizern in below comment, adding libz.dylib instead of libz.1.2.5.dylib should do the trick. This should link to the latest version of the lib (see this question and answers here).

Something with gZip library i guess... If somebody know an issue to fix that or an other good/complete XMLParse library, thanks to answer me :D
PS: If you had some difficults to read, i'm sorry for my english...
This type of error means that you haven't included a library or framework.
A quick Google of deflateInit2 tells me it's the libz framework.
If you add libz.dylib to your list of frameworks it should compile.
Hope that helps.
