MrSID support in Mapserver 4.4.1

[Yar Doroshenko]

Hi Guys,

Need some help:

I'm running Mapserver 4.4.1 on a Windows machine. I am using PHP. I got the
source code from http://mapserver.gis.umn.edu/win32binaries.html
(ms441oci.zip)

It is compiled with GDAL, but GDAL that it's compiled with doesn't support
MrSID.

I got LizardTech DSDK and compiled my own GDAL 1.2.5
It compiled fine, I'm able to view MrSID images with the mrsidviewer.
gdalinfo works fine on my mrsid image, see output below. I want to use
MrSID since my MrSIDs are only 60-70 Mb, and when I convert them to TIF -
they grow to 1.7 Gb each. The question is: how do I make my Mapserver 4.4.1
from http://mapserver.gis.umn.edu/win32binaries.html work with my GDAL
1.2.5 ??? Of course, I could compile my own Mapserver - but that's a very
error-prone process on a Windows machine. Does anyone know of an option to
reconfigure Mapserver 4.4.1 installation without having to rebuild it? Do I
simply need to point it to use frmts\mrsid drivers? Is there any way to
achieve this? I will be glad to share my GDAL 1.2.5 with MrSID support.

Here is how I defined my MrSID layer:

LAYER
 NAME "14_1_1.sid"
 data mrsid
 type raster
 status default
END

Here is gdalinfo output for my mrsid image:
