Current status of displaying mrsid images with mapserver

[Don Silvia]

Hi,

I'm hoping someone can give me some details on what it will take to
display mrsid images with mapserver 4.8.3.  I've searched the list
archive and I think I need to build gdal with mrsid support using the
LizardTech SDK, which in turn requires that I use gcc 2.95 or 3.2.
The problem I have is that the machine I have available is running
Fedora Core 4 with gcc 4.0.0.  So my questions are:

1. Has anyone successfully built gdal with mrsid support using a
version of gcc later than 3.2?

2. Is it feasible to install gcc 3.2 separately from a later version,
and have the two coexist peacefully?

3. If options 1 and 2 don't work for me, I could convert the mrsid
images to TIFFs, but that creates a TIFF file of over 120 MB from a
roughly 10 MB mrsid file.  The disk space isn't a problem, but how
well will mapserver perform with TIFFs that large?

Thanks,
