The problem is described here http://blog.omega-prime.co.uk/?p=96. When I was using macports, I would build GHC myself using:
>>* EXTRA_CABAL_CONFIGURE_FLAGS = --extra-include-dirs=/opt/local/include \ *>>* --extra-lib-dirs=/opt/local/lib * and >>* ./configure --with-iconv-includes=/opt/local/include \ *>>* --with-iconv-libraries=/opt/local/lib \ *>>* --with-gmp-includes=/opt/local/include \ *>>* --with-gmp-libraries=/opt/local/lib* as described here http://www.haskell.org/pipermail/haskell-cafe/2010-June/079204.html On Sun, Aug 31, 2014 at 4:39 PM, Peng Yu <pengyu...@gmail.com> wrote: > On Sat, Aug 30, 2014 at 3:41 PM, Brandon Allbery <allber...@gmail.com> > wrote: > > On Sat, Aug 30, 2014 at 4:33 PM, Peng Yu <pengyu...@gmail.com> wrote: > >> > >> Undefined symbols for architecture x86_64: > >> "_iconv", referenced from: > >> _hs_iconv in libHSbase-4.7.0.1.a(iconv.o) > > > > > > You are mixing stuff built against the system iconv with stuff built > against > > either MacPorts or Homebrew.
