I've known about this for a while. It seems rather lame that we should have to code around a bug in Texinfo that they have acknowledged and fixed. On the other hand, I think plenty of people will be using Texinfo 4.X for at least another two years.

I modified all the documentation and the munge-texi.pl script to use the prefix 'docX' instead of 'doc-' and HTML links now work for me. See this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/7eff3032d144).

I'm seeing this also.

The "seealso" links from one function to another in the HTML manual do not link to the correct target. The links from the "Function Index" do work correctly. The pdf and info manuals work correctly.

I have narrowed this down to a bug in texinfo 4.x that has been fixed in 5.0 and higher. The links generated between the @anchor and @ref tags are not consistent in 4.x if they contain non-alphanumeric characters (ours are "doc-FUNCTION").

For example:

  1. browse to http://www.gnu.org/software/octave/doc/interpreter/Utility-Functions.html
  2. click on "round" in ceil's seealso list
  3. observe the resulting wrong anchor in the address bar and page has not scrolled to the round function

The anchor target should be "#doc_002dround" but the link ends up going to "#doc%2dround".

Now that bug #38392 is fixed, one way to fix this would be to just make sure the official Octave releases and the manual published to the web site are always built with texinfo >= 5.0.

Or change munge-texi.pl to remove the "-" from function anchors and texinfo 4.x should be happy as well.
