Premature end of script error (WAS: Config'ing CGI's)

Yes! Thank you! I wouldn't be this far without the helpful advice from this
list.

So, here's what I have now, for the record:

<VirtualHost xxx.xxx.xxx.xxx>
DocumentRoot /var/www/virtualhosts/site/html
ServerName server.com
AddHandler cgi-script .cgi
<Directory /var/www/virtualhosts/site/html/bugzilla/>
Options +ExecCGI
</Directory>
</VirtualHost>

And this takes care of the execution and permissions problem. Thanks!

On to the next problem. ;o)

(This actually may be drifting away from an actual Apache issue, so, if it
is, let me know.)

Upon accessing this directory now, I get an Internal Server error. My error
logs show the following:


[Mon Apr 29 14:36:12 2002] [error] (2)No such file or directory: exec of
/var/www/virtualhosts/site/html/bugzilla/query.cgi failed
[Mon Apr 29 14:36:12 2002] [error] [client xxx.xxx.xxx.xxx] Premature end of
script headers: /var/www/virtualhosts/site/html/bugzilla/query.cgi

It appears that it both can NOT find the file AND that it CAN find the file,
but is puking on the headers. What does that mean? For the record, that file
does exist in that location.

Thanks Joshua...that appears to be part of the culprit. This BugZilla 
app has some messy scripting configurations in it.

Anyways, this appears to be more of a perl issue know...thanks for 
getting me to this point!

Those are actually both part of the same error.  When Apache execs the
script, it gets the response from the operating system "No such file ..."
and therefore it doesn't get the appropriate script headers.

The problem is almost surely that the shebang line at the top of the
script doesn't point to the correct location of perl.  Therefore,
when the OS goes to try to execute it, it fails.
