It seems you have a duplicated file:
ld: duplicate symbol ..........
For what i see its called ASIAuthenticationDialog.
Check for that one.

This error frequently shows when you import the .m file instead of the .h.
For example:
#import "Class.m"
When you're supposed to do this:
#import "Class.h"
Hope this helps!

If you are trying to build a project and not run unit tests then you need to remove the test cases from your main project. If your are building the test project then you will need to include the GHUnit project.

When i remove that FBConnect, then it again works fine. That FBConnect has a JSON folder and my application also has a JSON folder. But files in both folder have different names. How can i remove this error and make it work? Thanks in advance.
I think the file in the JSON folder is a duplicate.

How do i solve this problem? I tried looking around but found no answer how to solve it.
Your target does not include RMDBMapSource.m for compile sources, and probably more files. Check that your have included all files from route-me project to your target.

This looks like a linking problem caused by a less-than careful use of the framework.
Do you have a copy of the xmppframework linked and the sources included in your project, or two copies of the sources included in your project?
