I think from what you said in one of your previous emails that I need to build the whole of ghc. Am I correct? If so I think I follow the instructions in the building guide unless there is some other documentation you think I should look at? Dominic.

RE: possible readline license problem with ghc and -package util

Well, nothing like a good license debate to wake everyone up ;-) Anyone heard of a "bikeshed" discussion before? Firstly, let me make it clear that GHC won't be switching to the GPL or even a dual license in the forseeable future. The University of Glasgow agreed to the BSD license, and frankly I can't see them agreeing to the GPL. And it's been widely publicised that Microsoft won't touch the GPL with a bargepole; enough said. Personally, I wouldn't mind dual-licensing GHC, because in a sense that gives people more freedom: more freedom to choose which licensing terms they accept the code under. But I *do* believe that on its own the BSD license is morally the right choice. Sure, if the main line of GHC development moved to a non-free source base, then users would lose out; but I don't think that it is right to *legislate* against this by restricting the freedom of programmers. If the developers, by their own free will, decide to create a non-free fork, then so be it. After all, even the GPL can't force developers to continue working on the code if they don't want to. But let me set minds at rest by saying that I'm not aware of any plans, at Microsoft or otherwise, to create a non-free fork of GHC. Sven Moritz Hallberg <pesco(a)gmx.de> writes: > Put short, I'd like GHC to stay free. I'd like > the GHC source to remain available, and the developers to remain reachable, > touchable.

Understandably, you'd like continued access to an open source actively-developed top-of-the-line Haskell compiler. I don't believe using a license is the right way to achieve this, though; the best you can do is find a revenue stream and pay programmers to work on the free version (c.f. Microsoft :-).

Mostly the University of Glasgow. Various bits belong to other copyright holders: code from the Haskell Report(s), code from the FFI spec, the regex library from FreeBSD, and GMP. None of it is owned by Microsoft. Cheers, Simon

possible readline license problem with ghc and -package util
by Martin Norbäck 12 Jun '02

12 Jun '02

I have a problem with the readline license that applies to ghc, and programs compiled with ghc. The readline library is under the GPL license. This means that any program (including ghc) that links with this library must itself be licensed under the GPL. This is very unfortunate. I would suspect that this only applies if you actually use the Readline module, so I can just avoid that. However, using -package lang (to get the GetOpt module) links with -lreadline even though it's not necessary. So the resulting binary is dynamically linked with libreadline. My meaning is that this is not a license violation of readline, but I am no lawyer, and I recall Richard Stallman of the FSF says differently. Linking statically with -lreadline may be a solution, since the linker is smart and removes unused code in statically linked libraries. If only I could be sure that that's the fact. I think most ghc users have better things to do than to track licenses of libraries that ghc links your program to, so I suggest that the Readline module is either removed or moved to a separate package, so that there is no doubt that it's not linked in. Another question is what to do with ghc, ghc uses readline and is not licensed under the GPL. A possible GPL violation, at least it would be according to Richard Stallman.

Updating the net package

I need to update the net package so that I can pass setSocketOption IP_TTL. This is a one line change. I'm using 5.02.2. There weren't any versions of Socket.hsc tagged as 5.02.2 in the CVS repository but there was one tagged Revision 1.2 / (download) - annotate - [select for diffs] , Fri Aug 17 12:51:08 2001 UTC (9 months, 3 weeks ago) by simonmar Branch: MAIN CVS Tags: ghc-5-02-branch, ghc-5-02-3, ghc-5-02-1, ghc-5-02 Changes since 1.1: +18 -12 lines Diff to previous 1.1 Track updates to hslibs/net I downloaded this and tried to compile but it has the following in it: instance Show Socket where ... and quite rightly the compiler complains. I'm going to take the latest version (although it would be nice to know which one was included in 5.02.2). 1.

Is my naive approach of just recompiling the relevant module going to work? I'd rather avoid having to build the whole of ghc if I can. Many thanks, Dominic Steinitz

GHC Gentoo Linux package
by Sven Moritz Hallberg 11 Jun '02

11 Jun '02

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 OK, here it is. The GHC ebuild for Gentoo Linux has been incorporated in the official package tree (search http://www.gentoo.org/index-packages.html) This means that it is available to anyone running Gentoo, so you can now safely claim to run on that platform. While I'm at it, I have two questions: 1) Is there a package of unregisterised HC files for any version of GHC (4.08.2 preferably) downloadable anywhere? If not, does anyone have one lying around which might be made available? The ebuild is capable of attempting a bootstrap from unreg HC on platforms for which no platform-specific HC files exist. It expects a file http://www.haskell.org/ghc/dist/4.08.2/ghc-4.08.2-unreg-hc.tar.bz2 for that, which of course does not exist right now. I would try to build that file myself, but I'm completely out of time right now. :( 2) I read a comment somewhere (in some script or so) saying something along the lines of "once we are cross-compiling". Are there plans to make GHC able to cross-compile?
