Probably trying to sidestep the 'precision loss' error from the newer compilers due to sizeof(void*) != sizeof(int). Using a char* is sizeof() compatible with a void*. This was kinda covered last year in STR #2813: http://www.fltk.org/str.php?L2813 > We might need to see your code. > Just tested with gcc 4.7.2 and that works fine... Might be a 32bit compile? I get the precision loss error when I build that example on 4.4.6 with a 64bit box: $ make foo2 Compiling foo2.cxx... foo2.cxx: In function 'void cb_item1(Fl_Menu_*, void*)': foo2.cxx:15: error: cast from 'void*' to 'int' loses precision make: *** [foo2.o] Error 1 _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
