Hi All, I am trying to port Dillo to i.MX27 (ARM9) processor. Using LTIB build system (www.ltib.org) to cross-compile FLTK. I cross-compiled FLTK2, but it is crashing, I can't run any demo example. To FLTK1.3 everything works fine, I ran all examples successfully. To FLTK2 nothing works. I searched Internet for similar error, but nothing solves it. I tested these FLTK revision: fltk-2.0.x-r6793 fltk-2.0.x-r6101 It appears to crash at "fltk::setfont". In fact I can see "bad font: fixed" message just before that "Segmentation Fault". Could someone give me some suggestion to solve this issue? See below the gdb backtrace. I am running gdbserver on i.MX27 board (IP 192.168.0.180) Best Regards, Alan $ arm-elf-gdb /home/alan/ltib/rootfs/home/test/hello GNU gdb 6.6 Copyright (C) 2006 Free Software Foundation, Inc.

I'd probably encourage you to file a FLTK2 bug upstream or send an email to FLTK mailing list, however w.r.t FLTK2 I don't think they will fix it soon anyway. My POV is that they answer to bug reports but not fixing much. Michal
