I have a large number of ECW format raster images and would like to use with GDAL (and ultimately in QGIS) on Mac OSX.

Having seen that there is no official ESRI support for the ECW library on any other platform other than Windows, I managed to get hold of the old version of the libecwj2-3.3 library. There are a few versions knocking around, but none of them will successfully compile.

Anyone had any success compiling the ECW library on OSX (10.6.7) and then compiling GDAL with ECW support.

Thanks.

Jon.

See here:

you will need to install a "plugin" and then add (compiling I guess) the support into GDAL (using the SDK you MUST download from ERDAS, after accepting their license). For Linux the SDK is no more available (in the ERDAS site), and I don't remember to have seen something for OsX recently.

Good luck.

Thanks. I had installed from here but didn't see that there was a ECW plugin package available (under Individual Frameworks / GDLA). This is not included in the GDAL Complete package. Installed this and voilà, ECW format now supported. – Jon Bartlett Jun 12 '11 at 14:01
