Hien,
I think you will have a better chance of getting these questions answered by
posting them to the mapserver-users mail list. The error you are getting is
probably purely mapserver related, and has next to nothing to do with GDAL...
For your convenience I will send this to the mapserver list too, so you don't
have to post it again.
Cheers,
Vincent.
