Gary,
Set your paths like such on startup or as an environment variable:
GDAL_DATA points at the data dir that comes with gdal source.
PROJ_LIB point to the nad directory that you download from proj4 website

OK - I can get it to compile and not crash instantly (bonanza!)
However, when I try to create the OGR transform us
R["central_meridian",-124.5],PARAMETER["scale_factor",1],PARAMETER["false_easting",0],PARAMETER["false_northing",0],UNIT["metre",1,AUTHORITY["EPSG","9001"]]]
...and I am looking to output WGS84 lat/longs.

OK - having messed with GDAL for a couple of days now, I can display
imagery using the GDAL c++ classes to extract raster tiles.
However, I now need to be able to convert xPixel/Line couplets to
geo-positions (UTM, LL or whatever). I have scanned the classes and
have failed to come across a me
