[Gdal-dev] GDAL and fseeko

[Jonathan Greenberg]

Hi there, I was wondering if you might consider switching fseek references
to fseeko?  I'm having problems dealing with large (>> 4gb files) on a G5
mac, and I suspect that might be what's going on.  When I compile with the
--with-unix-stdio-64=yes flag I get the following errors:

make

Any ideas?  You'll notice I set the D_FILE_OFFSET_BITS flags also, although
turning these on and off doesn't seem to make a difference...
