After ./autogen.sh, "make po" and "make html",

So making HTML worked for you?
Then "libxslt" (containing xsltproc) and your docbook stylesheets ("docbook-xsl" on my system) are installed properly...

I recieved warnings while making pdf like below:

Making pdf? Oh god, you are way ahead of us! ;-)

warning: failed to load external entity "http://www.docbook.org/xml/4.3/docbookx.dtd" //OASIS//DTD DocBook XML V4.3//EN" "http://www.docbook.org/xml/4.3/docbookx.dtd".

Hmm, dblatex is using xsltproc.

type "locate docbookx.dtd" then I recieve this: /usr/share/xml/docbook/xml-dtd-4.3/docbookx.dtd.

Actually there is a docbookx.dtd file of docbook/xml version 4.3 on my system, how can I use it instead of load it from the internet? Any suggestion?

With the correct entries in your catalog file (e.g. /etc/xml/catalog). But this should be configured automatically, and since "make html" worked for you, the configuation should be ok.

Try "make pdf-xx DBLATEXFLAGS='--verbose'" (xx = your locale).

I tried to make a German pdf, and it worked (some error messages about "Missing character"s) after adding manually a link to the images directory.
