| I compiled FLTK 1.1.7 to Nokia 770 internet tablet platform (gcc --version displays sbox-arm-linux-gcc (GCC) 3.3.4 (Debian)) and it seems to work quite well. Only problem was that hypot() function. It exists in header files, but is missing from libraries causing linking errors.
It is easy fix by adding following implementation:
double hypot(double x, double y) { return sqrt(x*x + y*y); }
Because the platform used is probably not officially supported, this is marked with low priority. But it could be worth fixing... | |

| I'll be happy to fix this by addig a function. However, I need some unique #ifdef SOME_DEFINE that I can use to encapsulate the fix. | |

| Again, I'll be happy to put this in for your very specific compiler and environment. Since I do not own this equipment though, I would need some kind of #ifdef line that would make it possible to filter you compiler out.
Otherwise, I'll have to close this report. | |

| Might be enough to add a configure-time test for this, but at the same time we could just replace our use of hypot() with the corresponding sqrt() calls on all platforms - we're not saving *that* many cycles... :) | |
