Re: [Haskell-cafe] Building lambdabot
Wow, it sure has taken me a long time to get back to this, but I got it to
work! Two ways actually. I did them both from scratch, just to make sure I
understood what was going on and could communicate it for the next poor sap
that is as ignorant as I was.
All this is done with GHC-6.12.3, cabal, readline-1.0.1.0,
In both cases, readline needed to be install. On a mac, this is troublesome
because the mac comes with editline. Macports installs readline fine,
except you have to make sure it's universal ('port install readline
+universal') since GHC needs 32-bit libraries. When installing the haskell
readline package, cabal has to be told where to find the macports readline
('cabal install
--configuration-option=--with-readline-libraries=/opt/local/lib
--configuration-option=--with-readline-includes=/opt/local/include
--extra-lib-dirs=/opt/local/lib --extra-include-dirs=/opt/local/include
readline').
The two ways of installing lambdabot branch from here. The first is from
hackage, but it needs to be patched and I don't think the patch is complete
anymore. The patch is at
http://www.haskell.org/haskellwiki/Image:Lambdabot.patch.
cabal unpack lambdabot
cd lambdabot
wget patch url -O | patch -p1
cabal install --extra-lib-dirs=/opt/local/lib
--extra-include-dirs=/opt/local/include
lambdabot should compile, but will complain about arrows when run (because
the patch is insufficient). You can manually correct it, or try the other
method: installing from darcs.
'darcs get http://code.haskell.org/lambdabot'
(Note: you'll want mueval too:
http://www.haskell.org/haskellwiki/Lambdabot/Building)
I had to manually install Stream-0.3 as lambdabot required = 0.3 but
something else required Stream 0.4. 'cabal install' in the lambdabot dir
and it should be happy.
Should/can I update the haskellwiki with this install process? Should the
mac readline info go there too?
Thank you to everyone who helped me sort this out; I learned quite a bit.
Joe

What that error says to me is that GHC is failing to link against *any* iconv. I bet that it's because you have iconv installed via Macports without +universal. Try: $ file /opt/local/lib/libiconv.a It should say: /opt/local/lib/libiconv.a: Mach-O universal binary with 2 architectures /opt/local/lib/libiconv.a (for architecture i386): current ar archive random library /opt/local/lib/libiconv.a (for architecture x86_64):current ar archive random library If nothing else, I've learned about checking locations and architectures of libraries in this little adventure, so I had checked that prior to writing. I do in fact have the universal binary installed. What's more, both the macport and system versions are universal. I tried telling cabal to explicitly use each, separately, and it failed both times, though it gave me a different error when compiling against the system lib. (It complained about readline again, which is why I assumed readline had some dependency on iconv.) I'm going to try what Gwern recommended (using the darcs repository for lambdabot) before I continue down this route.

Re: [Haskell-cafe] Building lambdabot
Thanks, Max. I had seen that thread already, but I don't understand how it helps me. I'm on a x64 mac and I have both an i386 and x64 version of readline installed (via macports install readline +universal). Perhaps cabal is choosing the wrong one. How do I find out? How do I tell it which to use? And which do I want it to use?

Re: [Haskell-cafe] Building lambdabot
Thanks Max. That makes a lot of sense. That change got me to the point of linking lambdabot. I then encountered this error: Linking dist/build/lambdabot/lambdabot ...

Can I tell readline to use my Mac's iconv even though I installed it with MacPorts? ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] Building lambdabot
Rogan, Thanks for taking a look at it. No, mtl is not the problem, at least not yet. A detail that I've discovered is important: I'm on Mac OS X (10.6). readline is my problem, and readline + mac + haskell seems to be a bad mix. Macports installs readline in /opt/local/ by default, so I discovered I needed to install this way: cabal install lambdabot --configure-option=--with-readline-includes=/opt/local/include --configure-option=--with-readline-libraries=/opt/local/lib That got the readline dependency installed correctly, but then the lambdabot build complained about the architecture (32- vs 64-bit). This threadhttp://osdir.com/ml/librar...@haskell.org/2010-04/msg00171.html was somewhat helpful. I reinstalled readline via macports with the universal flag and got past that error. Now I'm stuck on readline again [lambdabot build step 28 of 81]: /Users/joe/.cabal/lib/readline-1.0.1.0/ghc-6.12.3/HSreadline-1.0.1.0.o: unknown symbol `_rl_basic_quote_characters' What do I do with that? ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
[Haskell-cafe] Building lambdabot
I've had a bit of an adventure trying to build and run lambdabothttp://hackage.haskell.org/package/lambdabot-4.2.2.1 on my box. 'cabal install lambdabot' does not work. It states it's not GHC 6.12 (and certainly not 7.0) compatible, but I tried 6.12 anyway and got nowhere. Next, I tried 6.10 but failed on the unix dependency (in the same manner as this threadhttp://web.archiveorange.com/archive/v/nDNOvQMXUGwfkyy0ITet). The thread is unresolved, so I've not tried modifying the cabal build-depends. I'm hoping to find someone who has a working lambdabot setup who can point me in the right direction. What further information about my struggles should I provide? Thanks, Joe ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
