This question already has an answer here:

I am using Lubuntu 14.10, QGIS 2.6, and Ubuntu GIS(unstable). QGIS was used to use GDAL 1.10, and can import ERDAS ecw format. But after GDAL upgraded to 1.11, QGIS couldn't import ecw images. How to solve this problem?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Perhaps you're missing the ECW libraries, on windows they (and MRSID) are separate and need to be downloaded and put into your GDAL_DRIVER_PATH folder (trac.osgeo.org/gdal/wiki/ConfigOptions#GDAL_DRIVER_PATH). – Michael Stimson Mar 22 '15 at 21:41
  • There was gdal-ecw-src 1.10, ECW 5.1.1 SDK and GDAL 1.10 with QGIS 2.4 before, and ecw could be imported successfully. After installed QGIS 2.6 and GDAL 1.11 updates,ecw cant be imported now. There was still gdal-ecw-src 1.10 library, I uninstalled this old package and I tryed to built gdal 1.11 with ecw again according to trac.osgeo.org/gdal/wiki/ECW. It has error as "checking for libNCSEcw.so or libecwj2... configure: error: not found in /usr/local/lib or /usr/local/bin". – Edip Ahmet Mar 22 '15 at 22:26
  • I think it is about old ecw SDK, there is an update of ecw SDK so I will install it and try to build it from source again. – Edip Ahmet Mar 22 '15 at 22:26
  • There were significant changes in the ECW SDK fairly recently, the whole driver has changed. The new ECW is read-only and supports the newest ERDAS ECW changes; possibly the previous (1.10) version may work if it's in the right spot. I can't help (or understand) with linux, sorry, I've been assimilated into Microsoft Windows and know no other. – Michael Stimson Mar 22 '15 at 22:47
  • I can import ECW on windows7 after installing via OsGeoW. Just problem with linux. – Edip Ahmet Mar 22 '15 at 22:56
