Hi, I have a problem making GDAL work with ECW files on Fedora Linux 17.
Here are the steps I did following the instructions on:
http://trac.osgeo.org/gdal/wiki/ECW
1. I downloaded, installed and compiled libecwj 3.3 library
2. I downloaded the source of gdal 1.9.1
3. I ran ./configure --with-ecw, make and make install
4. gdalinfo --formats now includes ECW
5. However, I have a problem opening any ECW file with GDAL. For example, I
downloaded the sample ECW files from
http://www.terracolor.net/sample_imagery.htmlhttp://
http://www.terracolor.net/sample_imagery.html . One of the files is called
Terracolor_SanFrancisco_US_15m.ecw
When I run gdalinfo Terracolor_SanFrancisco_US_15m.ecw I get a weird error:
terminate called after throwing an instance of 'std::length_error' what():
basic_string::_S_create Aborted (core dumped)
Other file types such as tiff or asc open with GDAL correctly.
Was anybody able to get GDAL running with ECW support on Linux?
Should I try to use the KAKADU library with GDAL instead of libecwj?
Any suggestions are welcome.

Hi,
I went exactly your route with recompiling gdal on Ubuntu 12.04 - no
problems whatsoever and I converted my ECW images to tiff using gdalwarp.
I suggest you download the (free?) Erdas viewer for ecw files and check
the integrity of your ecw image - maybe it got corrupt on your download.
HTH,
Zoltan
