[Gdal-dev] projection info in mapinfo tab files corrupt whenspecifying -a_srs or -s_srs and -t_srs in ogr2ogr

[Peter.Rushforth at statcan.ca]

Hi Daniel and Frank,

I added the -DMITAB_AFFINE_PARAMS option to the compilation, using
a cvs from 2006.05.30.

I get the following error:

g++ -Wall -fPIC -O2   -I.. -I../.. -I/bilbo05/rushpet/gdal/src/gdal-cvs-2006.05.30/port -I/bilbo05/rushpet/gdal/src/gdal-cvs-2006.05.30/gcore -I/bilbo05/rushpet/gdal/src/gdal-cvs-2006.05.30/alg -I/bilbo05/rushpet/gdal/src/gdal-cvs-2006.05.30/ogr -I/bilbo05/rushpet/gdal/src/gdal-cvs-2006.05.30/ogr/ogrsf_frmts -DOGR_ENABLED -I/bilbo05/rushpet/gdal/src/gdal-cvs-2006.05.30/port  -DOGR -DMITAB_AFFINE_PARAMS -c -o ../o/mitab_coordsys.o mitab_coordsys.cpp

make: *** [../o/mitab_coordsys.o] Error 1

Can you see what the problem is from this?
Thanks for your suggestions.
