LAMPP - CGI-Script not working

Question

Hello

I have got a LAMPP Webserver. I tried to open a CGI Script called "Hello.cgi".

It contains:

#!/usr/bin/perl
print "Hello World.\n";

The path is: /opt/lampp/htdocs/dashboard/cgi-bin/hello.cgi

When I open: "127.0.0.1/dashboard/cgi-bin/hello.cgi", I get following:

Server error!

The server encountered an internal error and was unable to complete your request.

Error message: End of script output before headers: hello.cgi

If you think this is a server error, please contact the webmaster.

The CGI Script is written in Perl.

If you need more informations about my problem, say it, please.

There are basically 100 different things that could be wrong. Did you check the server log? Have you tried running the script from the command line? Are you sending any HTTP headers? — Matt Jacob, Nov 27 '16 at 19:14
@MattJacob I ran it in the command line now, it worked. Thanks! — runasas, Nov 27 '16 at 19:34
Yeah, but... that just confirms that there's nothing wrong with the script itself. — Matt Jacob, Nov 27 '16 at 19:41

Firstly, you should never write a Perl program without including the lines use strict; and use warnings;.

Secondly, if you have problems with a CGI program, you should check the web server error log for more details of the problem.

Thirdly, the output from a CGI program needs to include a content type header. So you'll want to add the following:

print "Content-Type: text/plain\015\012\015\012";

This becomes easier if you use the CGI module:

use CGI;
print header('text/plain');

But really, in 2016, you shouldn't be writing CGI programs - there are plenty of good alternatives available.
