Linux and big ecw file

[Gianfranco Brescia]

Hi to all from Italy...
I have a problem with ecw files...I've installed
ecwsdk-3.1.25jan05-linux.tar.gz and gdal1.2.6.
When I use a small ecw file (230 Mbyte) it works good but when I want see
a big ecw file (9,8 GByte) I can see nothing... everything is in
background color...
Can somebody can help me, even if my English is not perfect?
Thanks a lot!
Bye.
