No, libtiff 3.X and 4.X are not ABI compatible, and have also a few API differences (but that are small enough so that the GDAL GTiff driver can be built against both) > This crazy idea came to my mind also : a configure option which would > allow prefixing all symbols exported by libtiff and libgeotiff. > But this means 2 projects to modify.

The whole question is how to implement such a configuration option. _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
