[GAP Forum] Package Digraphs on Windows

[Hebert Pérez-Rosés]

Thank you very much, Alexander. I do have GAP 4.11.1, but when I tried to
load the Digraphs package, GAP returned the error message that I attach
below. From what you say, I understand that I would have to build it in
Cygwin, and then I can use it normally, right?
