[Gdal-dev] ECW not building in

[Armin Burger]

I don't know if that's an option for you, but I asked the ER Mapper 
development support and got the download link for the SDK 3.3 beta. It 
just compiled under Linux without any modification using configure - 
make - make install. In GDAL I used --with-ecw=/usr/local   and 
everything worked fine.

Also all problems we had with some datasets and an older ECW version 
seem to have disappeared and the speed looks quite good. Mapserver 
processes a 3 GB ECW on a 3GHz Pentium in about 1 s or less, independend 
of the scale level. So I think the latest beta is worth trying it.
