Hello.

Could someone could shed some light what I should do. Please point me if
I should send to a different list.

Although my script ran fine on the command line. I've got the following
errors when running my script on apache

It is my test script and pretty much I took it from module's
documentation.

**** The odd thing is that it ran fine on command line but failed
on the browser.*******

According to my googling search, it might be something to do with
LD_LIBRARY_PATH or RPATH. I located the path for libgcc.so.1 and
added it to LD_LIBRARY_PATH but it didn't help. I don't know how
to add it to RPATH. When I installed both modules, they passed
the make tests.

Anyways, here is my code:

#!/dssweb/local-perl/bin/perl

use strict;
use warnings;
use diagnostics;
use GD::Graph::pie;
use CGI;

my @data = (
["1st","2nd","3rd","4th","5th","6th","7th", "8th", "9th"],
[ 1, 2, 5, 6, 3, 1.5, 1, 3, 4],
[ sort { $a <=> $b } (1, 2, 5, 6, 3, 1.5, 1, 3, 4) ]
);

my $graph = GD::Graph::pie->new(400, 300);

my $format = $graph->export_format;
my $q = new CGI;
print $q->header("image/$format");
binmode STDOUT;
print $graph->plot(\@data)->$format();

To avoid the internal server error you could use fatalsToBrowser. But
your error is because GD can't be loaded, specifically because it may
not have been installed correctly, or libgd is either not found or not
installed. Did you install GD through CPAN or using the standard 4 step
build process? Did 'make test' succeed? Is libgd installed and in a
normal location? You may need to provide an LD_LIBRARY_PATH or similar
in your web environment.

is libgcc.so.1 same as libgd? I think my libgd is good. and the
error message refers to libgcc.so.1.

I installed GD through the four steps. It passed the make test.
I added the path to libgcc.so.1 to LD_LIBRARY_PATH but not to the
libgd? Should I add it?

Thanks.

And here are the paths to the modules:

OK I got it. Just like to share what I've done. My cgi didn't see
libgcc. Therefore, I need to setEnv LD_LIBRARY_PATH to libgcc's
path in my httpd.conf

cheers.

No (at least I don't think) libgcc is I suspect something provided by
gcc, which is presumably your compiler. I wonder if the issue is that
your Perl is compiled with a different compiler? I am not an expert to
know whether that is libgcc complaining that it can't load GD.so, or if
that is Perl complaining that it can't load libgcc.

Certainly can't hurt right? Is the Perl used to install GD the same as
that you are calling in your scripts? Better to double check.

Since the script works command line then it is almost certainly
something about the web environment that is different, the linker path
is really the only thing I could see as having this particular affect.
If this doesn't get it you might redirect your query to
beginners@perl.org as there may be others more experienced with
internals specifics that can help there that don't peruse the CGI group.
