autogen.sh Failure: I/O error : Attempt to load network entity

[PhysixProject]

I attempted to compile from release 3.20 tarball and from git repo itself. Both fail with same error. The URL it is trying to download, http://docbook2x.sf.net/latest/xslt/man/docbook.xsl does exist and can be retrieved with wget.

./autogen.sh

It probably does not attempt to download anything from the network, but instead tries to parse the DTD, which is supposed to be in the sgml catalog even if it has a web URL. You need to install the docbook DTDs to make that work. Did you do that?

I did not. Thanks for your reply. :)

Assuming that fixed it, closing this bug. If not, feel free to reopen with more info.
