NOTE I recommend configuring and installing with java bindings as well curl, postgres, python and spatialite. If you only want ECW support you can drop all the other flags after it. As for the java bindings, these worked best for me with java-8-oracle and not with openjdk
# ./configure --with-ecw=/usr/local --with-python --with-spatialite --with-pg --with-curl --with-java=/usr/lib/jvm/java-8-oracle --with-jvm-lib=/usr/lib/jvm/java-8-oracle/jre/lib/amd64/server --with-jvm-lib-add-rpath=yes
Make sure you see ECW support marked as yes on the list
# sudo make
# sudo make install
After dinishing this you need to set the PATH and LD_LIBRARY_PATH environment variables so that GDAL could recognise the location of the ECW library (bu default /usr/local/lib). The easiest way i found to doing this is:
# echo 'export LD_LIBRARY_PATH=/usr/local/lib' >> ~/.profile
# echo 'export LD_LIBRARY_PATH=/usr/local/lib' >> ~/.bashrc
sudo ldconfig
Add the following rows to /etc/enviroment
GDAL_DATA="/usr/local/share/gdal"
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
JAVA_HOME="/usr/lib/jvm/java-8-oracle"
on Linux open a terminal
gdalinfo --formats | grep ECW
On Windows open CMD
gdalinfo --formats | findstr ECW
This is much easier as there are packaged versions you can get from gisinternals
Download a zipped GDAL copy,
for example release-1911-x64-gdal-2-4-0-mapserver-7-2-1 which is the latest release right now.
unzip its content and place the contents of its bin\gdal\apps and bin\gdal\plugins,bin\gdal\plugins in C:\Program Files\GDAL. also place the contents of bin\gdal-datainC:\Program Files\GDAL\Data`.
