Hi,

I have a problem related to this change.

I have downloaded the SVN version of GDAL, and tried to compile it. But 
it fails:

/bin/sh /home/jcr/gdal/libtool --mode=link	g++  gdalinfo.lo 
/home/jcr/gdal/libgdal.la -o gdalinfo
libtool: link: g++ .libs/gdalinfo.o -o .libs/gdalinfo 
/home/jcr/gdal/.libs/libgdal.so -L/usr/lib64 
-L/usr/lib64/postgresql-9.0/lib64 -lgeos_c /usr/lib64/libsqlite3.so 
/usr/lib64/libexpat.so /usr/lib64/libNCSEcw.so /usr/lib64/libNCSCnet.so 
/usr/lib64/libNCSUtil.so -lgif /usr/lib64/libgeotiff.so 
/usr/lib64/libproj.so -lm -ljpeg -ltiff -lpng -lpq -lpthread -lcurl -lrt

`NCSEcwEditWriteInfo'
/home/jcr/gdal/.libs/libgdal.so: undefined reference to `NCSEcwEditFreeInfo'
collect2: ld returned 1 exit status

If I add the libNCSEcwC.so library, it works:

g++ .libs/gdalinfo.o -o .libs/gdalinfo  /home/jcr/gdal/.libs/libgdal.so 
-L/usr/lib64 -L/usr/lib64/postgresql-9.0/lib64 -lgeos_c

/usr/lib64/libproj.so -lm -ljpeg -ltiff -lpng -lpq -lpthread -lcurl -lrt 
-lssl -lcrypto /usr/lib64/libgmp.so -ldl -lz

I am using libecwj2-3.3 on Linux 64 bits (Gentoo).
