[Gdal-dev] MrSID, GDAL & Mapserver

[Chapman, Martin]

Yar,
 
I really couldn't tell you whether it's all correct or not, but it looks like gdal read it just fine...which would mean your problem is somewhere else.  I did notice it's pretty big though.  It may take several minutes to open if MapServer is loading the whole thing.  Did you copy the new gdal lib and dll into the mapserver directory for libs?  Can you open it with the imageviewer exe that comes with the mrsid sdk?  It's in /bin or something like that.  Can you try to use a smaller sid file.  This sounds like a MapServer config issue to me.
 
Martin

	Thank you Frank and Martin,
	
	I got gdalinfo to work, I still cannot display my MrSID, and I'm getting the
	same error message in IE.
	
	I do get the following info when I run gdalinfo on my file:

	Any hints on what I should try next to display the MrSID, could it be a layer
	problem?
	
	Thank you!
