[gdal-dev] Java bindings with GDAL 1.4.4

[Meek, Allan (Contractor)]

I've run into a problem with the call to GetGCPs() in
http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/java/apps/gdalinfo.ja
va, line 177. I have the GDAL bindings properly compiled, with GDAL
1.4.4.

If I run the Java version of gdalinfo with an image that uses GCPs
(i.e., RADARSAT-1, ENVISAT), the program crashes whenever it calls
GetGCPs(). If I comment out that line, the program runs properly
(although it doesn't report the GCPs, of course).

Here's an example of the output I get:

==================

The generated logfile is available if anybody wants to have a look at
it.

This problem does not affect images that don't have GCPs, as the
preceding 'if' structure routes them around this part of the program.

Is there a simple solution to patch this up, or is this a deeper
problem?

Thanks,
Allan
