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. Corrado > Hi Corrado, > > I see. Looks like I have to find the time to compile a GDAL version with ECW > support.
