I want to enable read support from Erdas ECW files in gdal on windows.

I have GDAL binaries from here and I also have a self compiled version.

When compiling myself I have found the options in nmake.opt and could add support myself, but if its possible I would rather add it to the precombiled distribution from gisinternals. Is this possible? Or will I need to compile it my self?

  • If you use binaries from gisintenals, have you noticed the msi installer for ECW plugin gisinternals.com/sdk/…?

  • It worked, all the *.exe apps works, but the python scripts wont use the plugin. Is there python bindings from gisinternals also that can be added to python. (maybe the one i got from pip install is bad)

  • actually my python bindings came from: lfd.uci.edu/~gohlke/pythonlibs/#gdal since i could got get pip install to work.

  • On the same directory page I see "Installer for the GDAL python bindings (requires to install the GDAL core)"

For read access the easiest way to get ECW support is through the OSGeo4W installer. Do an Advanced install, and in the libs section enable the gdal-ecw library.
