I'm working on creating some distribution bundles of GHC 7.4.1 and HP 2012.2.0.0 for OSX 10.5 to help rectify the lack of support on older Macs. In building GHC I've run into a linking error in stage1:
ld: duplicate symbol ___gmpz_abs in libraries/integer-gmp/gmp/objs/add.o and libraries/integer-gmp/gmp/objs/abs.o
Hi, I ran into the same problem but managed to get it to work, finally. I run Mac OSX 10.5.8 on an Intel based Mac. 1) make sure you have Xcode 3.4.1 from the Apple Developers download site: You need gcc-4.2. Test this by doing this in a shell: $> gcc-4.2 -v According to the gmp developers this link error goes away when using gcc-4.2. See http://gmplib.org/list-archives/gmp-bugs/2010-January/001838.html 2) then I installed the "Haskell Platform 6.12.3" from http://www.haskell.org/ghc/download_ghc_6_12_3 http://www.haskell.org/ghc/download_ghc_6_12_3#macosxintel 3) download ghc-7.4.1.tar.bz2 http://www.haskell.org/ghc/download_ghc_7_4_2#sources 4) after unbzipping and untarring: $> cd ghc-7.4.2 $> ./configure --with-gcc=gcc-4.2 $> make (success!) $> make install (profit!) Hope you will manage to get it to work too! cheers, h verkouter
