[Gdal-dev] Warping of large files

I'm using VS.NET'03 on a WinXP SP2 computer. It took a while to get it set
up, but I was finally able to compile the ECW SDK 3.1RC1. You can refer to
the thread on the ERmapper forum to see what I had to do to get the SDK to
compile. (http://forums.ermapper.com/viewtopic.php?t=589) Tom Lynch says
that the problems I encountered will be fixed in RC2. In this case,
persistence paid off. None of the actual code in either ECW or gdal needed
changing. It was all a matter of cleaning up the build project files.

After setting the appropriate paths in the gdal build (nmake.opt from the
gdal cvs tarball gdalcvs-20050405.zip) I was able to get a successful build
of the whole package. I was able to do a gdal_translate from tiff into ecw
and perform the subset, also.

I'm not sure if this info will help you, but I wanted to say that it *can*
