hi Malte
i have now tried all the versions of fltk available... 1.7, 2.0.x-r6101, and version 2 from the SVN. i have compiled these from source but i still can't work out how to get the scons script to find fltk headers.  what am i doing wrong here. do i need somthing else in my scons file?

the SContruct file seems to  be looking for Fl.h which i have at /usr/include/fltk-1.1/FL/Fl.H

guiconf.Chguiconf.CheckLibWithHeader('fltk', 'FL/Fl.h','c++')

thanks..

scons still reports (using fltk 2 and svn 2)
