Hi,
I've succeeded in building a binary distribution that uses static
libraries for gmp and readline. libreadline.a, libncurses.a and
libgmp.a
with corresponding header files are included. (For license issues ask
someone else.)
On http://gmplib.org/ we find:
"GMP is distributed under the GNU LGPL. This license makes the
library free to
use, share, and improve, and allows you to pass on the result. The
license
gives freedoms, but also sets firm restrictions on the use with non-
free
programs."
I have not attempted to check whether your distribution fulfills the
requirements of the LGPL.
It does fullfil them. The source code of all components of the system
is available enabling users to build the same software with a
different version of GMP. That's all that the LGPL requires of
software linked against a LGPL library.
Further, on http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html:
"Readline is free software, distributed under the terms of the GNU
General
Public License, version 2. This means that if you want to use
Readline in a
program that you release or distribute to anyone, the program must
be free
software and have a GPL-compatible license."
For your distribution to adhere to this, it appears to require GHC
to have a
GPL-compatible license. I don't believe it does.
It does. GHC's codebase is a mix of BSD3, LGLP, and GPL. They are
perfectly compatible. See <http://www.fsf.org/licensing/licenses/index_html
>.
