Hi,
GHC HEAD now has support for using dynamic libraries by default (and in particular, using dynamic libraries and the system linker in GHCi) for a number of platforms.
I am very happy to hear this news. I have long been a quiet proponent for defaulting ghc and Cabal to shared libraries and dynamic linking for Linux. I think Fedora was probably the first Linux distro to enable ghc shared libs and use dynamic linking for executables in our packages. Having ghci and cabal linking benefiting from dynamic linking seems a positive step forward indeed IMHO. I hope we will see ghc shared libs support spreading also to other Linux archs (particularly ARM). Sure it will change deployment workflow somewhat but that is what Linux distros are for. :) I am looking forward to test this with Fedora's Haskell packages very much. Jens ps Btw RHEL is also increasingly moving to 64bit.
