Where is the error?

Hi Antonio,
I have been reported that this problem should be solved with the
latest GDAL version in the development branch.
Corado, another one using ECW, told me an alternative solution:

Hi Oliver,
I have found a solution. I was still using version 3.3 of the ECW
library since it is the last release for which source files are
available: it compiles, it links,... but it doesn't work.
Thus, I have downloaded the latest version of the ECW library (Release
5.0.1). Unfortunately, only binaries are available and the installer
only extracts the files (it does not install them). Thus, I have
manually installed the library according to the following procedure
$ cd /usr/local
$ sudo cp -r /(path to ecwjp2_sdk)/etc/ ./
$ sudo cp -r /(path to ecwjp2_sdk)/include/ ./
$ sudo cp -r /(path to ecwjp2_sdk)/lib/ ./
$ cd ./lib
$ sudo ln -s ./x64/release/libNCSEcw.so.5.0.1 libNCSEcw.so
or, depending on your architecture,
$ sudo ln -s ./x86/release/libNCSEcw.so.5.0.1 libNCSEcw.so
$ sudo ldconfig
Then, I downloaded and compiled gdal-1.10.0 by following the usual
procedure
cd /(path to gdal)
./configure --with-ecw=/usr/local
make
sudo make install (or checkinstall)
Finally, I compiled QLGT and... I'm newly able to open ECW files!!
I hope it can be useful for someone else.
