This is attempting to build fluid with your cross-compiler. A few observations. - You probably do not need to build fluid with the cross-tools, it seems unlikely you would want to run fluid on the target. A host version of fluid is probably much more useful. So this probably is not really a problem... - It looks like you are missing a maths library. With a gcc based compiler, that would normally be resolved by adding -lm to the end of your link line. Your tools may be different, but in essence you need to add whichever lib provides the maths functions. - You might be better off using one of the fltk 1.x series rather than fltk-2, since the 1.x series are considered stable and are more widely supported, and have been used in a number of places on embedded boards already.
