Hi, ok, getting there :).

No, the PKG_ADD file is from 2.9, it's the same as in src/. But I spilled some debug info out of mk-pkg-add and it seems that this line:

fcns=`$SED -n -e 's/XDEFUN\(X\|\)_DLD_INTERNAL *( *\("\|\)\ ([^", ]*\)[", ].*$/\3/p' $f | sort -u`

is broken on my system. It does not ever report a match. $fcns is then used to construct the autoload directives, so that produces my problem.

After some playing around I found that \(X\|\) and \("\|\) break it. Also subsituting with X\? and "\? does not work, following man re_format:

Obsolete (``basic'') regular expressions differ in several respects. `|' is an ordinary character and there is no equivalent for its functional- ity. `+' and `?' are ordinary characters, and their functionality can be
     expressed using bounds (`{1,}' or `{0,1}' respectively).

on my system I found that \? could be substituted by \{0,1\} so now I have

fcns=`$SED -n -e 's/XDEFUNX\{0,1\}_DLD_INTERNAL *( *"\{0,1\}\ ([^", ]*\)[", ].*$/\1/p' $f | sort -u`

and it works and should have the same behaviour. Must be Apple (or BSD) behaving different again (as with readline).

Anyhow, problem solved :). Thanks for the pointer!

In 2.9.6, you should also have some lines like this:

autoload ("__gnuplot_plot__", fullfile (fileparts (mfilename ("fullpath")), "__gnuplot_raw__.oct")); autoload ("__gnuplot_replot__", fullfile (fileparts (mfilename ("fullpath")), "__gnuplot_raw__.oct"));

in the PKG_ADD file that is in the directory with the .oct files.

Sorry that this is not well-documented, but you are using a
development version...

If you don't have any autoload commands in the PKG_ADD file, then
multiple functions in a .oct file will not work properly.  If the
autoload commands are missing, then something went wrong when the
PKG_ADD file was constructed.  Are you sure the PKG_ADD file you have
installed is actually from 2.9.6?

Also, Octave no longer uses the ls-R file, so it seems you still have
some files left over from an earlier installation.  I'd recommend
removing all that you can find and doing a fresh install.

Those files are just used during the build process to keep track of
some information extracted from the source files.  They are not
intended to be installed.
