Hi,
Somehow, if I put the <cvaux.h> from OpenCV library above <x10rt.h> then the
compiler complains. Otherwise, it works fine.
I think it's some trivial preprocessor definition problem or something since
my friend had similar problem when using System S.
The problem was two different libraries were using same preprocessor
definitions and header files were broken.
Thanks,
Kirak
