Morteza,

I suggested using the command "mapserv -v" to get the version information
which includes things like "INPUT=GDAL" if GDAL input support for rasters
is supported.   I don't think GDAL is picked up automatically when building
from source though I'm not sure.

Shapefiles and raster files use subtly different rules, and the shapefile
layer type is distinct in that an extension is not required.

GDAL does not support ArcGIS layer files (I'm guessing this is what
your .lay file is).  And if the file has an extension then you must
specify it (on linux or Windows).  And vectors aren't the same as
rasters.
