Hi Tim,

Thank again, I think my qgis build is not linked to my gdal built. So the problem I don’t know how to walk through this??? I guess I have to recompile qgis from sources ???

Yes you should be able to open ecw files in QGIS. But you need to make sure that your QGIS build is linking to your hand built gdal and not to any other gdal lying around on your system otherwise it isnt going to work!

Hi Tim,
Thank you for your answer. You’re right I think when I tried to build the source fron svn the server was overloaded. Even I re-tried and the first time the archives have been locked after unzipping the abunch of sources and the second time was the good one.

Finally, I successfully build gdal with the support of ECW format. Another question, when building ecw support format with gdal, could I add ECW and jpeg2000 raster files into QGIS. Looks like the ER-Mapper ecw and jpeg2000 are not available into qgis raster type ???

Thank again Tim

It was probably just the svn server being a bit overloaded or an issue with your connection. Try to wait a few hours and then update again. Otherwise take it up with the gdal team!

Hi Tim,

I’m getting problem with building dgal from trunk to enable ecw support following your post. I’m wondering what is going on… because when building from sources (using subversion) and I noticed that the process of importing files from trunk stop after 2 minutes and nothing happens… Could not follow up and could not figure out what i’m doing wrong. Here is a piece of shell commande to illustrate my issue.
