I made suggested modifications but it didn't seem to help. Here is the error log from apache:
Code:

Also in IE window I get this instead of the PDF file:

Code:
Content-Type: text/plain

This software is governed by the GNU General Public License, Version 2, and
is based in part on the work of the Independent JPEG Group.



Here is the config part of pdfreport.cgi
Code:
my( $HTMLDOC ) = "/usr/bin/htmldoc"; # location of htmldoc executable
my( $ROUTERSCGI ) = "/usr/local/mrtgweb/cgi-bin/routers2.cgi"; # location of routers2.cgi
my( $WORKDIR ) = "/tmp";             # temporary work directory
my( $WEBROOT ) = "/usr/local/mrtgweb/pdf";    # docroot for your web server
my( $CONFPATH ) = "/usr/local/mrtgweb/cfg";  # default path for cfg files
my( $VERSION ) = "1.0";


This is the permissions for $WEBROOT directory:
drwxrwxrwx 2 root root 4096 Jan 3 13:12 pdf

Any other ideas how it can be fixed?

Your system clearly is working very differently from mine...

I'll upgrade my htmldoc exec to match yours, and I'll check the code again. I think you may have a different perl version to me... I have 5.8.0, do you have 5.6 or even 5.005? I think you need at least 5.6.

Since I can't duplicate it, its a bit hard to do anything but treat the symptoms empirically.

To prevent the uninitialised value error, line 116 change to:
undef $ENV{QUERY_STRING} if(defined $ENV{QUERY_STRING});

(this is weird since QUERY_STRING really should be set. Maybe a perl version problem)

To stop htmldoc thinking it is running as a CGI, line 140 add:
$ENV{TMPDIR} = $tdir;
$ENV{TMP} = $tdir;
undef $ENV{QUERY_STRING};

(This looks like a htmldoc version problem, with htmldoc trying to be clever)

To prevent the prototype check error, line 59 remove ($) and change to:
sub readcfgfile {

(this might be a perl version problem)

I did all the suggested modifications but it didn't help. The only fixed error was the one regarding prototype check. I still get "Use of uninitialized value in undef operator" errors. Also, htmldoc is still "starting in CGI mode". Here is my perl version:
Code:
[user@comp user]$ perl -v

This is perl, v5.8.0 built for i386-linux-thread-multi
(with 1 registered patch, see perl -V for more detail)


This really could be the htmldoc problem by I don't know how to correctly remove existing version in order to install v1.8.23. I guess I'll just have to wait untill you upgrade yours to v1.8.24. In case it helps my OS is RedHat Enterprise Linux AS v3. (Linux host 2.4.21-4.ELsmp )

P.S. In case you didn't know it, there is a great piece of software for emulating hardware PC on Windows and Linux for installing "virtual" OS for debugging and testing purposes. It's called VMWare http://www.vmware.com/download/workstation.html

I've some other more urgent work on at the moment, so this is being a bit delayed. This is still on the to-do list, though. I think it may be the HTTP_REFERRER env var that it is using to (incorrectly) select CGI mode, so I'll look into that.

I have got the same problems as you and that comes from the htmldoc version. I have installed the 1.84 version and that doesn't work i have also the same error text/plain but now it works I have just installed the 1.83 version in the same path that the 1.84 and it has erased the previous version and now it works...

Yes, I have had other reports that 1.8.24 of HTMLDOC takes different parameters.

I have 1.8.23 here which works fine. I will install 1.8.24 at some time and make the required changes, but I'm a bit short on time. Also trying to get language setup for 2.16 ready for easter....

Check your version with 'htmldoc --version'

I was curious if anyone had ever gotten pdfreport to work after getting the "unitialized operator at undef operat" at line 117 error. I am trying to get this to work with htmldoc 1.8.23, perl 5.8.7 and routers2 version 2.16 beta 7. In my apache error_log I see this error at line 117 and 143,.

Sorry - worload has gotten the better of me. What with all the 'real' work, plus new release of routers2 and nagevlog, not to mention society work and small daughter, I've not been able to work on this and wont be able to for at least 2 months. It's in the pipeline, though...
