Ok, here we go, I used these Makefiles to build dynamic libraries linkedHave you tried to get X support for cygwin upstream into the fltk distribution?
against X. You may also integrate the changes into the usual Makefile templates, but I used these handcrafted files. I used them with fltk-1.1.4rc1, so there may be some additional problems with the code I don't know about.
Sofar I've had good response to my OSF and cygwin patches for fltk.
