Hope to get a solution to this from here at the earliest possibility. Once again thanks Regards Prashant Hello everyone, I am having a hard time debugging the undefined reference to <some_function> error. I made following changes: <a href="http://pastebin.com/DqqTsP7A" target="_blank">http://pastebin.com/DqqTsP7A</a>. Errors are: <a href="http://pastebin.com/PW0yzzgA" target="_blank">http://pastebin.com/PW0yzzgA</a>. I am porting String and its corresponding functions to OUString respectively. Any help shall be highly appreciable! Thanks Regards Prashant Pandey </div>
