The guide to install SDK to read /.ecw/ is here

The guide is for Ubuntu raring, using ubuntugis unstable repository.
For ecw support, you need the package libgdal-ecw.
This is at the moment only available for precise (12.04) and
raring(13.04), not for saucy (13.10) or trusty (14.04).
So it's more a question of ubuntu version, not qgis version.
Am I missing something? I haven't been able to see libgdal-ecw for
anything more recent than raring (13.04)?
No, as I wrote, raring is the last one available.
Unfortunately, ubuntugis has now trusty packages for qgis 2.2 and gdal,
but running with GDAL 1.11.0
If the libgdal-ecw for trusty does exist, then your link should work
with the change Andre mentions above, and use trusty where it says raring.
at the moment, it does not exist yet.
If it doesn't then this is the workaround that I used. It's a quite
hacky, and I'm not making any guarantees other than it works for me.
I would strongly suggest that these be read through before you do them
so you sort-of understand what you're doing first. Feel free to ask
questions. (or make corrections!)
Use your step 1-4 for qgis.org/debian above, and make sure you have a
working QGIS 2.2.
I used ubuntugis unstable, and got QGIS 2.2 working.
If you had a QGIS installed before you may need to totally
uninstall qgis python-qgis and their dependants.
This gets you a working qgis using GDAL 1.10
Install the ECW SDK.
[I'm still using the 3.3 SDK so I'm assuming the instructions in
your link are correct. From the recipe do these bits:]
Download ERDAS-ECW_JPEG_2000_SDK-5.1.1.bin in
http://download.intergraph.com/
http://downloada.erdas.com/software/2014/ECWJP2SDKSetup/v5.1.1.49_Linux/ECWJP2SDKSetup_5.1.1.bin
Search ERDAS ECW/JP2 SDK v5.1 (Linux) or click
http://download.intergraph.com/downloads/erdas-ecw-jp2-sdk-v5.1-%28linux%29?startdownload=1
That works too, but the file is now named ECWJP2SDKSetup_5.1.1.bin
So the next actions are
chmod +x ECWJP2SDKSetup_5.1.1.bin
./ECWJP2SDKSetup_5.1.1.bin #Select option desktop read only
sudo cp -r ERDAS-ECW_JPEG_2000_SDK-5.1.1 /usr/local/
sudo ln -s
/usr/local/ERDAS-ECW_JPEG_2000_SDK-5.1.1/Desktop_Read-Only/lib/x86/release/libNCSEcw.so
/usr/local/lib/libNCSEcw.so
these three lines should go in one.
Does it have to be x86, not x64?
wget
https://launchpad.net/~ubuntugis/+archive/ubuntugis-unstable/+files/libgdal-ecw-src_1.10.0-1~raring4_all.deb
ar vx libgdal-ecw-src_1.10.0-1~raring4_all.deb
tar -xzf data.tar.gz
sudo cp usr/src/libgdal-ecw-1.10.0.tar.gz /usr/src/
sudo cp usr/bin/gdal-ecw-build /usr/bin/
Run the script
sudo gdal-ecw-build /usr/local/
And then you should get something meaningful out of this and ecw files
should work.
gdalinfo --formats | grep ecw
unfortunately not. The script ends complaining about missing gdal-config.
At least I get no error starting QGIS.
