clang: error: linker command failed with exit code 1 (use -v to see invocation)

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!

I have searched for solutions to this error but nothing seems to solve my issue or be directly related. Any ideas on what I can do to solve it?
I did the translation directly in the files. You need to utilize NSLocalizedstring and a strings file to make this work otherwise xcode will try to use two .m files with the same name.

The solution is the same as we've discussed in the comments:
I checked your project and it does not have PagingScrollViewController. You're probably referencing it from outside the folder. Add it to the project too and it should work fine!
#CodaFi also had the correct answer so +1 to him too!
The class PagingScrollViewController is not in your compile list. In the file tree, click your project at the top, then go to your target>build phases expand 'compile phase', then drag the PagingScrollViewController.m file to the list and run.

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.

For what i see its called ASIAuthenticationDialog.
Check for that one.

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?
