[Catalyst] Template::Latex in Catalyst

[Yves Räber]

Thanks for your help, but it don't make any difference.
I added some information here, if maybe it will help.

Here is my exact code in the controller :

sub generate_bill : Local {
   my ($self, $c ) = @_;
  
   my $vars = ();
   my $res;
   my $output;
           
   use Template::Latex;
   use Template::Constants qw( :debug );
   Template::Latex->latex_paths({
        latex    => '/usr/bin/latex',
        pdflatex => '/usr/bin/pdflatex',
        dvips    => '/usr/bin/dvips',
    });  
   my $tt = Template::Latex->new({
           DEBUG => DEBUG_FILTERS | DEBUG_PLUGINS,         
        INCLUDE_PATH => '/home/yves/workspace/swixtel/root',
    });
   
   $c->log->dumper(Template::Latex->latex_paths());
                  
   $res = $tt->process('pdf_template.tt',$vars,\$output);
   $c->log->dumper("OUTPUT : $output | RES : $res");
}


And that's the Catalyst debug output :
