I have installed and configured DruTex (in my Drupal6 installation).

But when I go to create a page, a warning appears on the top of the page as:

warning: Parameter 1 to drutex_pdf_nodeapi() expected to be a reference, value given in /usr/share/drupal6/modules/drutex/drutex.module on line 829.

please help me in removing it.

Thanks.

Note: I used a @ in the mentioned file on line 829 however then following errors come when i create a page :

TeX Embedding failed!
