# ACM Conference Paper Error - \normalsize is not defined

I am using the ACM template from http://www.acm.org/publications/article-templates/proceedings-template.html .

I get the error:

The font size command \normalsize is not defined: there is probably something wrong with the class file.

My Document Begins like this:

\begin{document}
RequirePackage{graphicx}
\documentclass{sig-alternate-05-2015}


I am modifying the sig-alternate.tex file (no explicitly named main file is there).

• always in latex \documentclass comes first, then use \usepackage then \begin{document} – David Carlisle Nov 8 '15 at 10:20
• @DavidCarlisle THanks, I keep getting the error You have requested document class sig-alternate-05-2015', but the document class provides sig-alternate'. – ferrer Nov 8 '15 at 10:21
• @DavidCarlisle In the template I got from the link, there sig-alternate-05-2015.cls and sig-alternate-sample.tex – ferrer Nov 8 '15 at 10:22
• That is a bug in their file, but it's only a warning, ignore it (and complain to them:-) – David Carlisle Nov 8 '15 at 10:23
• @DavidCarlisle But in latexilla it is not compiling. I write new content and its doesn't show up in the pdf. – ferrer Nov 8 '15 at 10:24

The document should start (like all latex documents)

\documentclass{sig-alternate-05-2015}
\usepackage{graphics}
\begin{document}


You will get a warning

You have requested document class sig-alternate-05-2015',
but the document class provides sig-alternate'.


which you can ignore, or to stop it, edit the \ProvidesClass line in the file to say sig-alternate-05-2015 or save the file as sig-alternate.cls and use

\documentclass{sig-alternate}


Probably best just to ignore the warning and complain to the conference organisers and they should fix that bug.

• It is REquirePackAge in my case, it will also be At the same position ? – ferrer Nov 8 '15 at 10:29
• @ferrer No you should use \usepackage. (\RequirePackage works at that point but is the wrong command to use) – David Carlisle Nov 8 '15 at 10:36
