Followed instructions from various posts (each one with slight variations on the theme) and most of the time have no trouble getting the installed GDAL to accept ECW files. However, QGIS stubbornly refuses to accept the fact that GDAL is ECW-enabled and keeps telling me the format is not supported. As no one even mentions the mere fact that QGIS will NOT work even if GDAL itself does, I must be missing something really obvious somewhere (like the need to compile QGIS from source? How to otherwise get ECW in the list of supported raster files in the qgis settings menu...). Grateful if anyone could point that out to me in simple steps, as I've been spending more then a week now on this.
System info: - Virtual machines using VMWare workstation 7 on Win7 Pro. - LinuxMint12 (Ubuntu 11 Oneiric) with QGIS 1.7.4 upgraded to QGIS 1.8.0 and GDAL 1.9 - Clean LinuxMint 13 (Ubuntu 12 Precise) with QGIS 1.8 and GDAL 1.9 as installed from qgis package
In all cases gdalinfo --formats list ECW as supported and commandline gdal_translate and gdalwarp work fine with ECW as input and output (translate only), but QGIS knows better and refuses to even try.
