[gdal-dev] geoTransforms and OGRSpatialTransforms

[Smart, Gary]

Well, part of the problem seems to be that I was addressing a symbolic
link to the file and not the actual file itself.

Now that I'm addressing the file directly, BOTH files manage to create
the geo transform BUT NEITHER can generate the coordinate transformation
object (OGRCoordinateTransformation) .  Can anyone tell me why both
files give me the following message...?

 

ERROR 1:  No PROJ.4 translation for source SRS, coordinate
transformation initialization has failed.

 

I am using Linux SLES10 SP2, gdal-svn-trunk-2009.12.14 and
proj4-4.7.0-1.

    } // end case default
    free(tmp);
