Why if I use the \documentclass{book} for examples, the following code work, and if i use classicthesis i get errors? Sorry for the lenght, but this is the MWE.

In the example the \textwidth founded, don't is applied, so I don't think that the stuff related to the margins are implicated in the errors. The problem is with the .aux file for me.

  • Can you explain again what your problem is? Your example runs without errors here. Sep 2 '12 at 18:38
  • @StephanLehmke really do you have not errors?

The real problem is in the .aux file you're inputting. You find there commands like

\@writefile{toc}{\vspace {-\cftbeforechapskip }}
\@writefile{lof}{\deactivateaddvspace  }
\@writefile{lot}{\deactivateaddvspace  }

That means, the .aux file expects @ to be a letter.

Moving \makeatletter (which you're using anyway) upward before \input{\nameofthisfile.aux} makes the error go away.

btw, \jobname is set by the system to the name of the input file.
