I have little experience with latex but am using it to write my undergraduate project, recently the error messages have come up and it wont allow me to build my pdf and comes up with the following error messages.
pdfTeX warning (ext4): destination with the same identifier (name{page.1}) has
been already used, duplicate ignored
<to be read again>
\relax
LaTeX Warning: Citation `ci' on page j undefined on input line k.
I am using an embedded bibliography \begin{thebibliography}.
\bibitem{ci}in the bibliography, then\cite{ci}will work. – egreg Jan 24 '14 at 18:17
