I am trying to get the algebra filter to work on my site.
The expression @@x^2@@ returns the Undetermined error message.
I have followed the suggestions given in the forum to use algebradebug.php and everything renders OK.
Can anyone shed any light on why it should work if the expression is entered in algebradebug.php but not on a normal page.
Thanks
Hi Jonathan,
You need to have the HTML/Entities perl module installed. The package may be called something like perl-HTML-Parser.

Jonathan,
If you have Ubuntu, Perl and Apache 2 you need the following libraries:
sudo aptitude install libapache2-mod-perl2
sudo apache2ctl restart
Manuel.

Hi Mike,
You can get it here,
http://search.cpan.org/~gaas/HTML-Parser-3.56/
but it may already be part of your distribution. It is available pre-packaged with debian, ubuntu, opensuse, ...

If the expression is rendered by http://yoursite/filter/algebra/algebradebug.php, then I would assume that all the needed packages must already be installed. Other things to check:
- Has the Algebra filter been activated? (Site administration -> Modules -> Filters -> Algebra Notation "eye" open)
- Did you surround the expression by double @-signs?
- Can you get any Algebra expressions to render?
- Does TeX work? (you can use the same expression, but surrounded by double $-signs)
