[Haskell-cafe] GHCi fails to load C++ object files (missing symbol)

[Mark Wright]

Hi Yves,

It works (on Gentoo) when I compile it as a shared library.

% g++ -o libstuff.so -fpic -shared Stuff.cpp
% ghci Main.hs -L$PWD -lstuff               
GHCi, version 7.4.1: http://www.haskell.org/ghc/  :? for help
