I have some errors with my paper in LaTeX, and I don't understand how to fix the problems :

The first is :

pdfTeX warning (ext4): destination with the sa
me identifier (name{page.1}) has been already used, duplicate ignored
<to be read again> 

On google, I found that I have to add the option pdfpagelabels, but I still get this error.

Then I have an other error :

<to be read again> 
l.37 \chapter
             {Introduction} [1]

Just after the previous one. This one I have no idea how to fix the problem. I don't know why there is this eroor.

And the last one is a warning :

Overfull \hbox (16.278pt too wide) in paragraph at lines 43--44
\T1/cmr/m/n/10 I did my in-tern-ship in a lab-o-ra-tory in Nantes called [][]

I use the package acronym, but unfortunately the acronym is too long, and so I have the warning that a paragraph is too wide. Can fix it, and how ?

I give you the original document :



    pdfborder = {0 0 0}
\title{Prediction of Parallel Speed-ups for Las Vegas Algorithms}
\author{François Thiré}


\acrodef{lina}[Laboratoire d'Informatique de Nantes Altantique]{LINA}


I did my internship in a laboratory in Nantes calle \ac{lina}\footnote{Computer sciences laboratory of Nantes Atlantique}. The following      
words will present this laboratory.

    Strangely enough, your file works for me, but only after I make each character ASCII (not UTF8, your name is Francois Thire in my test). (Also removing the relevant packages inputenc and fontenc.) – Sean Allred Apr 29 '13 at 16:08

    Your file compiles without any problem here; only an overfull-box warning. Are you sure all your packages are up to date? – jub0bs Apr 29 '13 at 17:28

    With “error” you mean “warning” in the first two cases, right? They actually seem to belong to the same warning. It goes away when \maketitle is omitted but I have no idea why. – clemens Apr 29 '13 at 19:46
  • Inded, Latex write a PDF file. But I still don't know why I get these errors. – Saroupille Apr 30 '13 at 7:25

    You'll get better answers if you first try to write a minimal example. – Juan A. Navarro Apr 30 '13 at 18:37
