Hi, thanks for these instructions.

Everything seems to work fine, but when I run cabal update I get the following error:

wlan-n124-20:Desktop dmorti$ cabal update Config file /Users/dmorti/.cabal/config not found. Writing default configuration to /Users/dmorti/.cabal/config Downloading the latest package list from hackage.haskell.org cabal: user error (Codec.Compression.Zlib: premature end of compressed stream)

Any idea what's going on here? I found some mention of this problem occurring for windows users, but nothing about OSX...??

cheers!

Okay, now I tried running the cabal-install ./bootstrap.sh, and that installed everything as expected.

There's probably a more proper way to do this, but here's what worked. I created a bash script with this in it:

!/bin/sh

export LIBRARY_PATH=/sw/lib:$LIBRARY_PATH ./Setup build

And then I ran

$ sudo ./script.sh

That compiled zlib without complaining! Unfortunately cabal-install is still giving me the error:

$ ./Setup configure Configuring cabal-install-0.6.2... Setup: At least the following dependencies are missing: zlib >=0.4 && <0.6

And as far as I can tell, I just compiled zlib! Ugh.

Yeah, me neither. Thanks for the suggestions.

Try adding a -L/sw/lib option somewhere. That should tell the compiler to search that directory for libs too. But I’m really not an expert on neither gcc nor Haskell, far from it.

I installed gmp through fink…

$ fink list -i gmp
i gmp 4.2.4-1000 GNU multiple precision arithmetic library
i gmp-shlibs 4.2.4-1000 Shared library for gmp package
i libgmpxx-shlibs 4.2.4-1000 Shared C++ library for gmp package

$ ls /sw/lib/libgmp*
/sw/lib/libgmp.3.4.4.dylib /sw/lib/libgmpxx.4.0.4.dylib
/sw/lib/libgmp.3.dylib /sw/lib/libgmpxx.4.dylib
/sw/lib/libgmp.a /sw/lib/libgmpxx.a
/sw/lib/libgmp.dylib /sw/lib/libgmpxx.dylib
/sw/lib/libgmp.la /sw/lib/libgmpxx.la

But I’m getting the same error. Could it be that gcc is called from /usr/bin? Do I need to tell the compiler how to use -lgmp somehow?

(thanks for the feedback)

Your system is missing the library gmp (libgmp.a, the GNU multiprecision library). Install it via your system's package manager or manually (use Google).

Then the build should succeed.

When trying to install zlib, I get this error:

$ sudo ./Setup build
Preprocessing library zlib-0.5.0.0…
ld: library not found for -lgmp
collect2: ld returned 1 exit status
linking dist/build/Codec/Compression/Zlib/Stream_hsc_make.o failed
command was: /usr/bin/gcc -lz -L/sw/lib/ghc-6.8.3/lib/bytestring-0.9.0.1.1 -L/sw/lib/ghc-6.8.3/lib/array-0.1.0.0 -L/sw/lib/ghc-6.8.3/lib/base-3.0.2.0 -L/sw/lib/ghc-6.8.3 -lm -lgmp -ldl dist/build/Codec/Compression/Zlib/Stream_hsc_make.o -o dist/build/Codec/Compression/Zlib/Stream_hsc_make

Do you know what ” -lgmp” means, or what I should look for?
