Problem with cgi script

Dear friends,

Thank you for your very useful tutorials on CGI for my last node Where can I read perl CGI?

I have tried my first cgi program. The problem is that nothing gets displayed in browser. I am using firefox 2.0.

use CGI;
my $cgi = CGI->new;
print $cgi->header(),
$cgi->start_html(),
$cgi->p("Hello World"),
$cgi->end_html();
[download]

First, I executed the code in command line. It prints the expected output. Then, I tried perl -c to check the syntax, it said ok. But, when I tried in browser, nothing gets printed.

I have the file in cgi-bin directory, which is configured. I have given the permission as 777 for the file.

Help me to proceed..

The first thing is to check in your web server error log. The webserver tells you what happens. Also, you're not printing the HTML elements. Start with an even simpler script: `use strict; use CGI; my $cgi = CGI->new; print $cgi->header; print '<html><body>Hello World</body></html>';` [download] Then, modify that script to print out the HTML generated by CGI: `... print $cgi->header(); print $cgi->start_html(); print $cgi->p("Hello World"); print $cgi->end_html();` [download]	[reply] [d/l] [select]

That simple script is also not working in the browser.	[reply]

Well - what does the webserver error log say? Knowing the error message is the first step in solving the problem.	[reply]

This might be a longshot but are you sure your cgi-bin is in a permitted "place" and that the path you specify (in, presumptively, something.html) actually points to your script? (Some server/configurations take care of this for you by allowing that any call to <c>cgi-bin/script.cgi<c> get directed to a particular directory.) Customarily, cgi-bin is a sub-dir of your root. However, Apache can be configured to require or allow that it be elsewhere -- for example: / /cgi-bin /html /sub-dir1 /sub-dir2 index.html foo.html ... or / /html /cgi-bin /sub-dir1 /sub-dir2 index.html ... Depending on your server and its configuration, your script may ( have to be named script.cgi \| allowed to named script.cgi or script.pl ) or some variant of those possibilities. Those variants include something like this: / /cgi-bin /html /cgi-bin /sub-dir1 /sub-dir2 index.html ... which can be confusing.	[reply]

Check the logfiles of your apache webserver, they normally are in /var/log/apache2/. Also firefox can show you the source text of the page it shows (right klick on the page to get a menu). Do you see a correct html page there?	[reply]
