[gdal-dev] Compiling with ECW/JP2ECW support enabled

[Jonathan Williams]

I have tried this; I've added the Ubuntu-GIS repository, but none of the
builds are for 64 bit 14.04 LTS, from what I've seen.

I've also tried to force the issue with the instructions here:
http://gis.stackexchange.com/a/102088

However, the build fails, perhaps because I'm using version 5.2.1 of
ERDAS' SDK with libNCSEcw.so.5.2.1, or perhaps because I'm using Gdal
2.0.2? the compile messages indicate a couple of errors.


/usr/local/include/gdal_priv.h:226:19: error: ‘char**
GDALOpenInfo::papszSiblingFiles’ is private
     char        **papszSiblingFiles;
                   ^
ecwdataset.cpp:2526:48: error: within this context
                                    poOpenInfo->papszSiblingFiles, NULL );
                                                ^
make: *** [ecwdataset.o] Error 1

...as well as...

ecwdataset.cpp:440:91: error: no matching function for call to
‘ECWRasterBand::SetDefaultHistogram(double&, double&, int&, int*&)’


Note that I did *not* attempt to install QGIS or libgdal-dev, as I was
concerned some of the other dependencies might regress work that I'd
done with compiling Jasper, etc.

Best,
Jonathan
