Question

I have a Drupal 6.14 site with Views module. I have a view and on the primary links I put a link to the view.

There is a way to hide the link in the primary menu only if the view is empty?

You could probably do this either via a theme or module implementation of preprocess_page (THEMENAME_preprocess_page(&$vars) or MODULENAME_preprocess_page(&$vars)), but mac above is correct in that views are not known to be empty or not until they are run, so there will be a performance hit.

Within the function, you should have access to the structured primary links array, so you can run the view:

 $view = views_get_view('view_name');
 // Swap out 'default' for a different display as needed. Also, $args are arguments, and can be left out if not applicable.
 $output = $view->preview('default', $args);
 if (empty($view->result)) {
   // The view has no results, alter the primary links here to remove the link in question.
 }
