Hi Maitland, Thanks for the detailed reply! I will adjust my include paths accordingly. On my system, it seems that libqwt-dev cannot be installed in parallel with libqwt5-qt4-dev. Nevertheless, it is not an issue for my build, since the libs coexist and linking is correct. It is only a header issue. Thanks for clearing that up.
