GHC 7, Platform 2011.2 vs OS X 10.5, Ubuntu 11.04

[TL;DR: there's a concrete question at the bottom.] Once again I find myself in the pleasant situation where the slings and arrows of life in general are slightly less intense, and I manage to find a few spare minutes and some free brain cycles to dedicate to Haskell. Why not try GHC 7.0.3? (after all, GHC 7 has been out for a good few months, so the teething troubles should have passed by now), and there's a lovely new Haskell Platform 2011.2.0.1 to go with it, so, maybe this time, I'll actually be able to use some of the libraries that I tried and failed to install during my last period of Haskell study. The two computers I have available for playing with Haskell run OS X Leopard (10.5), and Ubuntu Natty (11.04). First up OS X: It seems that GHC 7 (and consequently Platform 2011.2) require OS X 10.6. OK, let's forget that one. Next up: Ubuntu. There's a Linux Link on the Haskell Platform Page. Ooooh, there's an Ubuntu link. Ooooh! there's even a package for Natty, great! Version 2010.1.0.0.1 WTF? Where's the 2011.2 package? There isn't one. OOoooKaaaayyyy. Any workarounds. Well, we can install from source, apparently. But we need GHC 7.0.3 first. Fine. Done. Now let's install the platorm. [Does obvious thing, compilation fails.] Hmm, let's follow the "Complete instructions for installing from source" http://www.vex.net/~trebla/haskell/haskell-platform.xhtml just in case I did something stupid. [Follows instructions: failure.] OK, maybe something somewhere is causing some confusion with previously installed versions of GHC, Cabal, whatever. [Performs Haskell pogrom on system: removes all traces of anything Haskell related. Follows "Complete instructions [...]" WORD ... FOR ... WORD. Failure]. Aaaaaaaaaaaaaaaaaaaargh ! I can't take it any more. I just want to write some Haskell, and every time I want to venture beyond the safe confines of the Prelude I get bogged down in installation hell. Next time I have some spare time, I will be more reluctant to risk having that time stolen by the Haskell infrastructure installation process. So, after this tale of agony, here are two concrete questions: a) Am I right in concluding that GHC 7.0.3 will not run on OS X 10.5 (without unreasonable effort)? b) On Ubuntu Natty I installed the generic linux GHC 7.0.3 binary. Downloaded Haskell Platform 2011.2.0.1 source distribution. ./ configure worked happily. make fails as follows. Building transformers-0.2.2.0 "/usr/local/haskell-platform-2011.2.0.1/bin/ghc" "--make" "Setup" "-o" "Setup" "-package" "Cabal-1.10.1.0" <command line>: cannot satisfy -package Cabal-1.10.1.0: Cabal-1.10.1.0-1fb2094e19492373b1a39284193e7984 is unusable due to missing or recursive dependencies: process-1.0.1.5-55dfaccf3a91c4cb8f6284a0bafef198 Could anybody help me get past this problem?

This is a frustrating situation. Note that there is a binary for 7.0.1 that supports 10.5 http://www.haskell.org/ghc/download_ghc_7_0_1#macosxintel. From this, you should be able to build 7.0.3 yourself. One minor note: if you're interested in LLVM, stick to the 32-bit build.! If you encounter problems, #haskell will help. As for the platform, if it is giving you trouble, don't shy away from just using GHC and cabal as normal! After you've cabal installed a few big packages, you will find that you've acquired many of the most popular packages.

The Ubuntu HP story is a bit of a gotcha for the innocent user, too. But, again, you can happily install GHC 7.0.3, and then cabal install your way to happiness. The problem you encountered seems due to a conflict among packages that came with GHC. I think your strategy of nuking everything Haskell through your package manager (if available), then manually (not forgetting ~/.ghc and ~/.cabal) was prudent to get out of the hole you found yourself in. But don't let HP installation troubles keep you away from Haskell altogether! Anthony

Maybe if I managed to install just one package manually, then I might start sharing some of you optimism :-)

...

The problem you encountered seems due to a conflict among packages that came with GHC.

Which does seem rather odd, doesn't it? I'm tempted to think that I didn't quite manage to nuke everything, because I find it hard to believe that GHC itself comes with internal conflicts which The Google seems not to have heard about.

...

I think your strategy of nuking everything Haskell through your package manager (if available), then manually (not forgetting ~/.ghc and ~/.cabal) was prudent to get out of the hole you found yourself in.

Yup, ~/.ghc and ~/.cabal didn't escape my attention. Except that it doesn't seem to have worked (yet - hope springs eternal). When I ghc-pkg check, I get lots of complaints about ~/.cabal/lib/ somelibrary/ghc-7.0.3 not being found. Erm, I nuked it all and then installed ghc-7.0.3 from scratch (generic Linux binary package), so I've no idea *why* my system thinks that these should exist unless *it* put them there after the purge during the installation of ghc. Any ideas how to solve this?

...

But don't let HP installation troubles keep you away from Haskell altogether!

I'm determined not to let that happen, but when the few precious moments I can afford to spend on Haskell end up being spent on installation troubles rather than Haskell itself, then it does become rather tough to keep the motivation.

Hmm, maybe I was mistaken, and maybe ~/.ghc survived. I nuked everything again (there was a .ghc: I assumed it had been re-created, but maybe it was an old one (I didn't check the datestamps), but no .cabal). Now 'make' and 'make install' *have* worked for HP. Haven't got around to trying to use it yet, but I thought I'd share the good news. Thanks for your moral support, it seems to have done the trick :-) Conclusion: I *probably* failed to remove ~/.ghc, so some old data were interfering with the supposedly clean installation. A manual install of the GHC 7.0.3 generic Linux binary, followed by installation from source of HP 2011.2.0.1 *has* worked for me on Ubuntu Natty, once I nuked *all* previous traces of Haksell on the system. I *did* have to install libgmp in order for the configuration step of HP to succeed. Thanks for your help.

It's easy, assuming you have installed alex and happy (and preferably hscolour), just download and unpack the source bundle, $ ./configure --prefix=wherever If it says it's going to build pdf and ps docs, that may fail if you have the wrong version of dblatex. $ make && make install Go play a football match or something, that takes a while.

That's not very comfortable, since you have to chase dependencies manually. Spending some effort to get cabal-install installed is definitely worth it.

Probably some package.conf.d survived the purge and was picked up by the fresh ghc. If you've deleted ~/.ghc, that would be in /usr/xxx. If you dare not messing around there, you could install ghc under $HOME, that shouldn't pick it up then.

This gave me some deja vu so I checked my sent mail, turns out on May 19 I wrote about the same thing. I updated one wiki page to not point to that cabal page, but I don't have permissions to take down the page itself. No one responded to my email so I forgot I had sent it and never been answered. So I repeat: If you search for "cabal install", the first link is http://hackage.haskell.org/trac/hackage/wiki/CabalInstall, which in turn leads to http://haskell.org/cabal/download.html. It looks very official and canonical and all that, but that page has an old version of cabal install that will no longer compile with ghc7 because it requires old libraries. Of course it won't tell you that right off, first it will install a whole bunch of old stuff, charge you a fiver, and then emit some "constraint can't be satisfied" msgs which if you have some experience with haskell and cabal already should eventually tip you off that something's wrong. Is there someone out there who has permissions to either take that page down, or replace it with a link to the new version at http://hackage.haskell.org/package/cabal-install? I updated http://hackage.haskell.org/trac/hackage/wiki/CabalInstall to point to the platform and to the hackage page, but the cabal page at http://haskell.org/haskellwiki/Cabal-Install still links to http://haskell.org/cabal/download.html. Should I just replace the haskellwiki page with a link to the hackagewiki one? I would try to port over any up to date info of course.

How am I supposed to interpret the constraint on base? I read that as "it has to be not less than 4 but less than 3 ...". In other words, it requires an *impossible* version of base ! 'ghc-pkg list' claims that I have base 4.3.1.0 filepath 1.2.0.0

Why not try GHC 7.0.3?

The two computers I have available for playing with Haskell run OS X Leopard (10.5), and Ubuntu Natty (11.04).

I can't say anything about OS X, but I've been using ghc 7.0.3 under Ubuntu. I just cabal-install what I want - and use apt-get for any required C libraries. To set up cabal-install, the bootstrap.sh script which should come in the package is helpful - it automatically downloads the required dependencies. http://hackage.haskell.org/trac/hackage/wiki/CabalInstall

...

Next up: Ubuntu. There's a Linux Link on the Haskell Platform Page. Ooooh, there's an Ubuntu link. Ooooh! there's even a package for Natty, great! Version 2010.1.0.0.1 WTF? Where's the 2011.2 package? There isn't one.

I see there is a 2011.2 package for the next version, but it's probably too much trouble to fix up the other dependencies.

...

b) On Ubuntu Natty I installed the generic linux GHC 7.0.3 binary. Downloaded Haskell Platform 2011.2.0.1 source distribution. ./configure worked happily. make fails as follows.

Building transformers-0.2.2.0 "/usr/local/haskell-platform-2011.2.0.1/bin/ghc" "--make" "Setup" "-o" "Setup" "-package" "Cabal-1.10.1.0" <command line>: cannot satisfy -package Cabal-1.10.1.0: Cabal-1.10.1.0-1fb2094e19492373b1a39284193e7984 is unusable due to missing or recursive dependencies: process-1.0.1.5-55dfaccf3a91c4cb8f6284a0bafef198

That's odd. I think 7.0.3 comes with Cabal-1.10.1.0.

Summarizing, by answering my own question on the basis of the help I have received elsewhere in the thread. On 2011 May 23, at 11:17, Jacek Generowicz wrote:

a) Am I right in concluding that GHC 7.0.3 will not run on OS X 10.5 (without unreasonable effort)?

It takes little effort on the part of the human, though the CPU will have to work hard. - Make sure you have XCode 3.1 (or better, I guess) - Download and install GHC-7.0.1 http://www.haskell.org/ghc/download_ghc_7_0_1#macosxintel - Use the above to compile GHC-7.0.3 from source.

...

b) On Ubuntu Natty I installed the generic linux GHC 7.0.3 binary. Downloaded Haskell Platform 2011.2.0.1 source distribution. ./ configure worked happily. make fails as follows.

Building transformers-0.2.2.0 "/usr/local/haskell-platform-2011.2.0.1/bin/ghc" "--make" "Setup" "- o" "Setup" "-package" "Cabal-1.10.1.0" <command line>: cannot satisfy -package Cabal-1.10.1.0: Cabal-1.10.1.0-1fb2094e19492373b1a39284193e7984 is unusable due to missing or recursive dependencies: process-1.0.1.5-55dfaccf3a91c4cb8f6284a0bafef198

Could anybody help me get past this problem?

This problem was probably caused by having an old ~/.ghc lying around. On a *clean* Natty system, this procedure works like a charm, though you may have to apt-get install some required C libraries. If you then proceed to install cabal-install, make sure *not* to use the version which is available for download (today) on the cabal- install page: for GHC 7 you need to use cabal-install version 0.10.*, which you can get from http://hackage.haskell.org/package/cabal-install Use the booststrap.sh script which comes in the bundle (chmod u+x bootstrap.sh; ./bootstrap.sh). Thanks to all those who helped. Hopefully this summary will be of some use to someone in the future.
