Re: [Haskell-cafe] Problems building lambdabot on osx
Hi, there is a conflict between ghc' libiconv and Ports installed libiconv. make sure first sudo port deactivate -f libiconv then install again, it should work. however, it is very ugly since your other port installed libraries needs libiconv, like gnuplot, so when you need port installed libiconv, sudo port activate -f libiconv again. 于 11-8-8 下午9:38, Adam Turoff 写道: I've tried off and on the last couple of days to build Lambdabot on Mac OS X (before and after the upgrade from 10.6 to 10.7) and I keep running into linker errors with the 64-bit Haskell Platform (ghc 7.0.3).

Re: [Haskell-cafe] Problems building lambdabot on osx
I didn't have any trouble building lambdabot when linking to readline built through Homebrew. Currently using Lion, Xcode 4.1, and GHC 7.0.4.

Yep, this is Apple's problem and everyone else just has to put up with it. If you want to mix macports and a non-macports ghc, I think the best solution is to self-compile ghc against the macports libiconv. This is easy, just configure ghc with ./configure --with-iconv-includes=/opt/local/include --with-iconv-libraries=/opt/local/lib I haven't had a problem since I started building ghc this way (10.5 and 10.6).

[Haskell-cafe] Problems building lambdabot on osx
I've tried off and on the last couple of days to build Lambdabot on Mac OS X (before and after the upgrade from 10.6 to 10.7) and I keep running into linker errors with the 64-bit Haskell Platform (ghc 7.0.3).

Anyone have a clue where to start to work around this? Would switching to ghc HEAD help here? My usually technique for solving readline-related issues is to rip-out readline from whatever I want to build, substituting in Haskeline if I want nice editing. It isn't very scientific, but I find it to be a more interesting problem to solve. I've given this a try in the Lambdabot source, but I'm getting unrelated errors building it so I'm not sure it works. Ripping out readline should be a brief bit of hacking in Plugin/OfflineRC.hs, from what I can tell.
