Re: problem compiling MTL example: dot_prod.cc

By now, you need to apply a few patches to mtl to get it to work
correctly with newer gcc

Check my mtl package on software.opensuse.org

(select search options, uncheck exclude home projects)

The source of the package shows you the necessary patches
