When the build of any version of Samba 4.* gets to the stage where the man pages are being built on a Solaris 10 machine, you get errors such as: I/O error : Attempt to load network entity http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd ../source4/torture/man/gentest.1.xml:2: warning: failed to load external entity "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd" This is a Solaris bug. The xml catalog is not properly set up. To fix this, edit the file /usr/share/sgml/db42xml/catalog.xml and add the following just above the last line in the file. <!-- Now the part that is really needed .................................. --> <rewriteSystem systemIdStartString="http://www.oasis-open.org/docbook/xml/4.2/ent" rewritePrefix="/usr/share/sgml/db42xml/ent"/> <rewriteURI uriStartString="http://www.oasis-open.org/docbook/xml/4.2/ent" rewritePrefix="/usr/share/sgml/db42xml/ent"/> <rewriteSystem systemIdStartString="http://www.oasis-open.org/docbook/xml/4.2" rewritePrefix="/usr/share/sgml/db42xml"/> <rewriteURI uriStartString="http://www.oasis-open.org/docbook/xml/4.2" rewritePrefix="/usr/share/sgml/db42xml"/> Tom Schulz Applied Dynamics Intl. schulz at adi.com
