Hi Patrick again, You are right. It was a problem with my Docbook installation.I copied an empty file 'index.sgml' into the html directory, and the building has continued.But I don't know exactly where the problem is. I have installed: - sg - docbook - docbook-xsl-stylesheets Do I need some more packages?
