A more or less elegant solution to the rpath problem was found in a previous thread [1]: Using GHC `-dynload=deploy' flag [3] and a `/etc/ld.so.conf.d/haskell.conf' file which specify the location of the shared libraries, e.g. `/usr/lib/ghc-7.6.3/sharedg'. Details in [2]. This solution was working well for most of the package, I remember being able to build pandoc with shared libraries, but sadly not for gtk, which has a kind of bootstrapping method that was not working with `-dynload=deploy' flag. It was with GHC 7.6, but as show in [3] the option is still present in latest GHC. Maybe it is worth another try, gtk could have changed! Not sure to have the time, but if yes I'll try it again. ++ Fabien [1] http://comments.gmane.org/gmane.comp.lang.haskell.arch-linux/1792 [2] http://permalink.gmane.org/gmane.comp.lang.haskell.arch-linux/1795 [3] https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/using-shared-libs.html#finding-shared-libs
