I have no problem with the principle of this. However I definitely think it
will need documenting in freebsd.sgml (or maybe tcpip.sgml if you think it fits
better there) because this trick won't be obvious!

Still need to add to network docs the sample code showing how to disable IPv6

I suggest keeping this bug open till the doc is done, as a reminder. Either
that or open a new bug. It can stay as low priority though.

Thank you for new chapter! It builds okay. I would only use eCos coding
style in PROGRAMLISTING and avoid CamelCase naming. If you want I can
re-indent that snippet, test its build and send the diff here.

Ah, I forgot about the indentation and naming.  That code came out of
our application source, so it uses our application coding style
instead of the standard eCos style.

I've tried several times over the years to get the right tools
installed and set up to build the docs, but I've never been
successful, I installed openjade this morning and then did some
googling with the doc build errors I saw, but didn't get very far.

So, if you want to tweak the code sample and then check the build, that
would be great.  You can commit the change if you want, or if you want
to post a revised patch, I can do the commit.

I wrote a memo for myself (but this is a debian-centric way). Copy that
memo here.

The eCos documentation writes itself in SGML format. To generate
documentation in HTML form you need to have the James Clark's DSSL
Engine (jade) and modular DocBook DSSSL stylesheets for print and HTML.
So, on Debian/Ubuntu, you have to install

  % sudo apt-get install jade docbook docbook-dsssl

Create new directory, e.g. /tmp/build, go there and type

  % $ECOS_REPOSITORY/../doc/sgml/makemakefile
  % make html

To generate eCos documents in PDF form you need pdfjadeTex package, it
is a version of TeX that can create PDF files as well as DVI files.
Install jatetex package

  % sudo apt-get install jadetex

and make PDF file

  % make pdfa4

Ah!  The dsssl part was one thing I was missing.  FWIW on Gentoo, the
packages you need are:

  openjade
  docbook-sgml
  docbook-dsssl-stylesheets

The "jade" package on Gentoo is a "FIPA-compliant Java Agent
Development Environment" (whatever that is).

> Create new directory, e.g. /tmp/build, go there and type
>

That works -- though I find HTML documents that are chopped up into
hundreds and hundreds of tiny pieces to be rather useless.  You can't
skim throgh the document and it's not possible to search for
something.  It's good enough for verifying changes to the SGML though,
so that's something.

I don't suppose there's any way to build the document as a single
page?

I've got jadetex installed, but doing "make pdfa4" or "make pdfletter"
doesn't produce a pdf file, just a .tex file.

  $ make pdfa4
  cp
../ecos-working/doc/sgml/../../packages/devs/eth/synth/ecosynth/current/doc/overview.png
 [....]
  jade -o ecos-ref-a4.tex -t tex -V tex-backend  -d

  make: *** [ecos-ref-a4.pdf] Error 1

  $ ls -l *.tex
  -rw-r--r-- 1 grante users 8043272 Mar  9 16:37 ecos-ref-a4.tex

Running "pdfjadetex ecos-ref-a4.tex" fails due to TeX capacity being exceeded:

  ! TeX capacity exceeded, sorry [number of strings=37193].

I tried increasing the max_strings for pdfjadetex by a factor of 6 to
500000, but it didn't make any difference.

Running jadetex instead of pdfjadetex exits with the same error, but it does
produce a .dvi file.  But, running dvipdf on that dvi file fails because

  GPL Ghostscript 9.04: ERROR: A pdfmark destination page 311 points beyond the
last page 310.

I'm now officially giving up on building eCos docs for I think the
fifth time...

Thanks for all the work Grant, and also to Sergei.

Is it too late to mention that at one point you use "staic" instead of "stack"?
:-) I've fixed this - too small to even need a ChangeLog.

Good to know, but, IMHO, they have chosen bad name for that

It is possible, I found how to do that

  http://www.dpawson.co.uk/docbook/dsssl/dssslhtml.html

When I fixed $(MAIN_HTML) rule in pkgconf/rules.doc (added -V nochunks,
and appended >$@), I got not chunked single html file.  So, it is easy
to add there (in eCos rules.doc) new rule, e.g. `onehtml' to get such an
output. Though, there are some graphic files out the HTML. I really do
prefer chunked output.

Old story. I call that in past I fixed `texmf.cnf' on Slackware, then I
did it on old Ubuntu distros, but, at the end (I hope) the pdfjatetex
limits became adequate the modern computers. I looked on that, I have

  %%
  %% jacking up TeX settings for the unique uses of jadetex
  %%
  extra_mem_bot.jadetex = 85000
  extra_mem_bot.pdfjadetex = 85000

[FYI] On my distro `texmf.cnf' is an auto-generated file now and the
settings itself are placed under `/etc/texmf/textmf.d' directory.

:-( I'm sorry. May be try it in the 16th? :-)
