Description Lina Pezzella (RETIRED) gentoo-dev 2004-07-19 13:13:54 UTC
JPGraph depends on gd and php.  If you emerge JPGraph it will automatically compile gd, but it will not change your use flags so that php is compiled with gd support.  This is an ebuild specific problem.

Furthermore, if USE=gd is in your useflags, you still have to add the line extension=libgd.so.x to php.ini in order to use JPGraph.  Minimally, USE=gd should automatically add that extension to php.ini, but what about people who do not have USE=gd and emerge JPGraph?

Here's a php script to test with:
<?php
ob_start();
include ("/usr/lib/php/jpgraph/jpgraph.php");
include ("/usr/lib/php/jpgraph/jpgraph_bar.php");

$data = array(5, 4, 3);
$leg = array('gongloo', 'j4rg0n', 'awesome');
$graph = new Graph(250,150,"auto");
$graph->SetScale("textint");
$graph->img->SetMargin(50,30,50,50);
$graph->xaxis->SetTickLabels($leg);

$bplot = new BarPlot($data);
$bplot->SetFillColor("lightgreen"); // Fill color
$bplot->value->Show();
$bplot->value->SetColor("black","navy");

$graph->Add($bplot);
$graph->Stroke(output.png);
ob_flush();
?>

<html>
<body><img src="output.png" /></body>
</html>

Reproducible: Always
Steps to Reproduce:
1. emerge jpgraph
2. place the script above somewhere in your document root

adding extension=libgd in php.ini is NOT the solution.
there are a number of problems like this thruout the tree, all waiting for use-flag forcing in dependancies (2.0.52 i'm told).
with PHP we try to build a monolithic PHP, as it's significently faster than having lots of shared extensions.

P.S. please do NOT assign php bugs directly to me, assign them to the php-bugs alias.
