GD demo cgi script works on command line but not on webserver.

[Peroli]

Hi all,
I recently installed GD version 2.34. The installation process went
well, except that it said, it cannot find -liconv library. It also said
its harmless.
I executed the demo script GD-2.34/demo/shapes.pl and it worked
well.
Then I executed GD-2.34/demo/gd_example.cgi, where i changed the
shebang line to the right version of perl and it failed. The error is
as follows:

$im->arc(50,50,95,75,0,360,$blue);

# And fill it with red
$im->fill(50,50,$red);

binmode STDOUT;

# Convert the image to PNG and print it on standard output
print $im->png();

Running it on the command line works fine. I don't know why it fails
while apache is executing it.

Is your server configured to run CGI scripts in a chroot "jail"? If so, then
libjpeg may not be visible from inside the jail, even though it's visible
from your normal login environment.

Thanks, sherm. That was the problem. Apache doesn't see this
directory at all. Problem solved.
