Hi,

Sorry for the very late answer, I guess you found a solution since then.
I reply for the record. I just experienced the same problem while
testing the hdsp tools on amd64. It appears that the cr2 helper function
from fltk, called from fl_draw_pixmap, which I use both in hdspconf and
hdspmixer, is badly broken on x86_64 in fltk 1.1.4 (the version shipped
with your FC3, Gentoo and maybe some other distros). I appears to be
fixed in the latest version (1.1.6). Takashi, is there some autoconf
magic we could add to warn about the problem ? Or maybe we could just
add a line to the README file ?

Thomas
