Talk:ECW

For the lazy ones (tested with Debian)

wget http://mirror.ovh.net/gentoo-distfiles/distfiles/libecwj2-3.3-2006-09-06.zip
unzip libecwj2-3.3-2006-09-06.zip
wget http://trac.osgeo.org/gdal/raw-attachment/ticket/3162/libecwj2-3.3-msvc90-fixes.patch
patch -p0 < libecwj2-3.3-msvc90-fixes.patch
wget http://trac.osgeo.org/gdal/raw-attachment/ticket/3366/libecwj2-3.3-NCSPhysicalMemorySize-Linux.patch
cd libecwj2-3.3/
patch -p0 < ../libecwj2-3.3-NCSPhysicalMemorySize-Linux.patch

(Also the patches from here and here should be applied. Without them, conversion from .ecw to geotiff failed for me.)
