Hello, Where does ghci look for .hi files from packages? (I doesn't seem to be the same place as ghc). AFAICT it expects to find them relative to the current directory, and I can only get it to work by cding to the appropriate directory *before* invoking ghci (doing this from within ghci seems to really mess things up). But I guess this isn't what's supposed to happen because this solution will only work with one package. My package entry looks like this.. Package {name = "Data.Tree.AVL", auto = True, import_dirs = ["/home/adrian/HaskellLibs/Data.Tree.AVL/pkg"], source_dirs = [], library_dirs = ["/home/adrian/HaskellLibs/Data.Tree.AVL/pkg"], hs_libraries = ["Data.Tree.AVL"], extra_libraries = [], include_dirs = [], c_includes = [], package_deps = ["base", "Data.COrdering"], extra_ghc_opts = [], extra_cc_opts = [], extra_ld_opts = [], framework_dirs = [], extra_frameworks = []} Is there something missing here?
