[mapserver-users] Problem with ecw raster layer

Fri Nov 4 05:07:15 EDT 2011

Hi,

I was thinking about that too but I just believed that you would get some informative error message about not-supported image format. Perhaps this might lead to a new ticket, developers?

Hi, thanks a lot for your response, that was the problem (no ecw support for gdal).
I solved it using Jeff McKenna method:

ECW is a proprietary format and thus may not have been installed with
your Linux distro. I'm not familiar with Scientific Linux so I don't
know. If you do have ECW support it would be handled by GDAL, which
you have as evidenced by INPUT=GDAL, so you need to determine if GDAL
has ECW support, which is pretty easy. In the shell:
  gdalinfo --formats
or better yet
  gdalinfo --formats | grep -i ecw
will list the formats tha GDAL can handle in your setup.

If ECW isn't in the list then you need to install or build supporting
libraries, but I have no idea how you do that in Scientific Linux.

HTH,
Rich
