[gdal-dev] VSI issue

[Ari Jolma]

Hi,

A few days ago on this list I mentioned that the following works using a 
recent version from trunk (and Perl bindings):

use Geo::GDAL;
$datasource = Geo::OGR::Open('/home/ajolma/data/parks.shp');
Geo::OGR::Driver('GML')->Copy($datasource, '/dev/stdout');

I'm testing a simple WFS written in Perl and basically the above is the 
contents of the GetFeature subroutine (the datasource name comes of 
course from a configuration file). However, using this in a Perl CGI 
program leads to "RuntimeError Failed to create GML file /dev/stdout." - 
it seems like the VSI does not work when the Perl program is run as a 
CGI program. I may investigate the issue more but maybe somebody has an 
answer right away. - I can forward the output to a file and then send 
the file but it would be nice to feed it directly to the client.

Regards,

Ari
