I have a Python software package Foobar that, amongst other things, uses gnuplot for displaying graphs on the command line. The gnuplot license is open-source, but not compatible with the GPL, so if I were to license Foobar under the GPL, nobody could legally use it. Is this correct?
What licenses is the gnuplot license compatible with?
gnuplotcommand line program with that string as input, and fetches the output. – Nico Schlömer Dec 14 '20 at 22:22
