Document Classes ⇒ Beamer problem: my old beamer files no longer compile

[TetheredSun]

Greetings!

I've just reinstalled my system (upgrading from Vista to Windows 7), so I had to reinstall MiKTeX as well. I've installed MiKTeX 2.9.

My problem is, my trusty old beamer files (that worked like a charm under MiKTeX 2.7 and Vista) no longer compile. I tried uninstalling MiKTeX 2.9 and reverting to the old 2.7 repository I store on my computer, but to no avail.

I've tried to google the error messages, but I haven't found anything that could help. I've tried to update MiKTeX, but it says no updates are available (no wonder since I use a freshly downloaded repository).

The error messages I get depend on the beamer opions and themes I use.

1) With

Code: Select all

\documentclass[10pt, blackandwhite, xcolor = {x11names, svgnames}]{beamer}

and Szeged, infolines, circles themes I get the following error:

! Argument of \@gobble has an extra }.

2) With

Code: Select all

\documentclass[10pt, xcolor = {x11names, svgnames}]{beamer}

and infolines, rounded, serif themes, I get

! Use of \beamer@alt doesn't match its definition.

and

! Use of \beamer@label doesn't match its definition.

I am very much dependent on these beamer files in my teaching. I've been using them for years without problem, and now I can't see a solution.

I should appreciate any help or hint from the community. Thank you very much in advance!

It is always helpful to prepare a minimal example. Here it is indispensable. With this poor information the problem is not comprehensible.

Dear Localghost

First of all, I am sincerely sorry for having breached the rules. My head was reeling from hours of useless search. And so much the worse as in trying to find a minimal example, I have found the solution.

The minimal example:

Code: Select all

\documentclass{beamer} 
\usepackage[magyar]{babel} 
\usepackage{caption} 

\begin{document} 
\begin{frame} 
        \frametitle{Title} 
                \begin{figure}[h] 
                        \centering 
                        \includegraphics[width = 0.5\textwidth]{Forms} 
                        \label{Forms} 
                \end{figure} 
\end{frame} 
\end{document}

Further conditions for the error to occur:
1) The magyar.ldf language definition is the old one included in the
MiKTeX distribution (they keep including the outdated one, even if the
freshest distributions).
2) The figure does not have a caption. If I insert a caption, the
problem is resolved.


The solution was to replace the magyar.ldf with a newer (1.5) version
(downloadable from http://www.math.bme.hu/latex/ ).

My sincerest apologies and thank you for the advice.

Yours sincerely
Péter

Now that the problem is solved, please be so kind and mark the topic accordingly as written in Section 3 of the Board Rules.

[…] 1) The magyar.ldf language definition is the old one included in the MiKTeX distribution (they keep including the outdated one, even if the freshest distributions). […]

This is worth a note to the maintainer of the MiKTeX distribution.

[…] 2) The figure does not have a caption. If I insert a caption, the problem is resolved. […]

Very odd. On my TeX Live 2010 it runs smoothly even with a caption.

[…] The solution was to replace the magyar.ldf with a newer (1.5) version (downloadable from http://www.math.bme.hu/latex/ ). […]

As mentioned above the MiKTeX maintainer should be informed to fix this.

Looking at the final solution, this problem should not only occur with the beamer class because it seems to be far from being specific for that class.

I've done as instructed, including notifying Christian Schenk at the MikTeX project of the problem. Sorry again for breaching the rules.
