Sorry, but you still misunderstand me:
I'm not ignoring the rules, I don't read them.
That's a big difference.
Anyhow, thankyou for your hint concerning the topic we're discussing here.
I already read that instructions (for building FLTK), at the first place, since the beginning.
And ... as I already stated many times in this thread ...
they DO NOT WORK.
There is missing the autoconfig, configure, msys or whatever.
And these tools in turn ... yes, no joke ... need other tools ... like perl etc.
Fine-fine!
(To tell the truth I since long have the suspicion that M$ places it's "dementors"
in open source scene. Busy posters ... ;-)
To close this thread by a useful hint.
This (on a private website) does the job:
