[gdal-dev] gdal_retile error

[christian.mueller at nvoe.at]

Perhaps a problem with the file permissions ?
After creating the tiles for level 0, the utility wants to create a  
subdir called "1" and store the tiles for level 1 in this subdir.

Check this with your user. Make
mkdir 1
cd 1
touch test.tif
rm test.tif
