[Gdal-dev] Supporting ECW as a plugin on window,

[Daniele Romagnoli]

Hi,
I did a similar thing on 1.4.4 and 1.5.3.
Basically, you are building ECW driver as a plugin as stated by the flag
ECW_PLUGIN = YES
Therefore, you need to do a separate build of the ECW GDAL Driver.
Go in gdal/frmts/ecw and run "nmake /f makefile.vc plugin"
This command should produce a gdal_ECW_JP2ECW.DLL.

Finally you need to define a GDAL_DRIVER_PATH environment variable linking
to the location where you have built gdal_ECW_JP2ECW.DLL.
After this, gdalinfo should find the ECW driver.

Let me know if you have additional issues, since I did these steps on 1.4.4
which needed some fixes that I have copied from 1.6.0 code. (I guess 1.6.0
already contains all the proper declarations)

Regards,
Daniele
