Hi,
Jukka, thank you very much for discussion, it was helpful. For now I found
what was wrong.
Gabe, maybe it's useful for you too:
my mapserv compilation was both with --with-gdal and --with-tiff, when I
recompiled it removing native TIFF support (--without-tiff),
then this recompilation was successful:)
Have a nice day,
Raivo
