I'm under SuSE 10.1 machine trying to build ECW toolkit and then build GDAL
against it but got no sucess.

I tryed to build libecwj2-3.3 package using:

$ cd Source/NCSBuildQmake/
$ make -f Makefile-linux-shared
.... then outputs:

Hi Eduardo,

I may have seen that issue before.  I've got a feeling that it was fixed
with a forward declaration

class CNCSJPCResample;

in NCSJP2FileView.h.  The problem didn't occur with most compilers, and it's
caused by the compiler being unaware that CNCSJPCResample is a type (and
hence anticipating it to be a variable name).

Alternatively, May I suggest you use the GNU autotools build files instead,
if convenient?  If you continue to see issues with those files I'll assist
you until you get things working.

Regards
