Premature end of script headers

[salc76]

I installed an apache server on Redhat 8.0. Most CGI scripts that I run fail. I receive the following message from the server.

Server error!
The server encountered an internal error and was unable to complete your request.
Error message:
Premature end of script headers: assi1final.cgi
If you think this is a server error, please contact the webmaster
Error 500

However, running the follwing script works fine,

#!/usr/bin/perl -wT
print "Content-type: text/html\n\n";
print "Hello, world!\n";

How can I correct this problem? Any ideas??

shebang line might be wrong, try it without the initial forward slash and no switches:

#!usr/bin/perl

Kevin, could the problem be a configration issue? That means apache server does not know a perl code with a extention '.cgi'?

actualy, I miss-read the first post, salc76 said:

>>However, running the follwing script works fine,

so the shebag line must be OK.

It could be a problem with the extension.

Are you saying to change the extension of the script from .cgi to .pl?

The following is a simple script that works:

#!/usr/bin/perl -wT
print "Content-type: text/html\n\n";
print "Hello, world!\n";



The following is a simple script that produces the above stated error:

#!/usr/bin/perl -wT
use CGI qwstandard);
use CGI::Carp qw(warningsToBrowser fatalsToBrowser);
use strict;

print header;
print start_html("Thank You");
print h2("Thank You");

my %form;
foreach my $p (param()) {
$form{$p} = param($p);
print "$p = $form{$p}<br>\n";
}
print end_html

can you check the server error logs? You might see something about "can't locate CGI.pm in @INC" in which case there is a problem with the script finding the CGI module.

Your right. Take a look at the following error log that was generated,

[Tue Apr 17 17:35:07 2007] [error] [client 192.168.1.120] Can't locate CGI.pm in @INC (@INC contains: /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0) at /var/

line 3.

Ho do I fix this?

CGI.pm has been a core module for a long time. You can try installing it if you wanted too but if you have a tech suport person to ask that might be better. Maybe they deleted CGI.pm for a reason.
