Hi All I am very new to the area of CGI (on top I am a biologist try to develop a web page for my results) hence some of the questions may seem to be trivial and that I would have dome something really silly. To train my self first, I wrote a simple perl cgi script which can display an image (dynamically generated using perl GD module) when opened in the browser. After discussing some of the basic stuff in this forum, I was finally able to set up the web server running but still not successful in executing my script. When I run the script from the browser (http://127.0.0.1:8080/cgi-bin/simpleImage.cgi), I get an 500 internal server error with the folloing message in the error logs 
[Fri Jul 29 12:28:44 2005] [error] (8)Exec format error: exec of /home
+/nagesh/apache/cgi-bin/simpleImage.cgi failed
[Fri Jul 29 12:28:44 2005] [error] [client 127.0.0.1] Premature end of

When I run the same script from the command line, it generate the binary for the image. Does this mean that my server configuration is not right?

simpleImage.cgi 

my $LIB = defined $ENV{LD_LIBRARY_PATH} ? $ENV{LD_LIBRARY_PATH} : "";
$ENV{LD_LIBRARY_PATH} = "/usr/lib:$LIB";

#!/usr/local/bin/perl

use strict;
use GD;
use CGI;

# This creates a Web GIF image on the fly 

# create a new image 
$im = new GD::Image(1000,100); 
# allocate some colors 
 
        $white = $im ->colorAllocate(255,255,255);
        $black= $im ->colorAllocate(0,0,0);
        $red = $im ->colorAllocate(255,100,0);
        $blue= $im ->colorAllocate(0,150,255);
        $yellow= $im ->colorAllocate(255,200,0);
        $pink= $im ->colorAllocate(150,0,150);
        $im->filledRectangle(10,5,990,15,$pink);
        $im->arc(10,10,10,10,0,360,$black);
        $im->fill(10,10,$white);
        $im->arc(990,10,10,10,270,90,$black);
        $im->fillToBorder(990,10,$black,$pink);

# Convert the image to GIF and print it on standard output 
#binmode STDOUT;        
print "Content-type: image/gif\n\n"; 
print $im->gif;

I made the code executable by chmod 755 simpleImage.cgi

This problem does not occur when I tested with a simple cgi script to check whether the server is able to execute the .cgi script and indeed it was working fine as I got some display on the browser. test.cgi #!/usr/local/bin/perl -w use strict; use CGI; my $cgi = new CGI; print $cgi->header(-type => 'text/html'); print "This is a test message"; Thanks very much in advance.

Update: Got the problem fixed. Thanks to all of you guys who helped out. See you all very soon with more problems Cheers
