Dear all,
I'm getting a rather unfriendly error when trying to load a plugin
with hs-plugins:
my_program: Ix{Int}.index: Index (65536) out of range ((0,7))
The exact numbers in the message vary depending on what I'm trying to
do. I'm using GHC-6.6.1 on MacOS X. Here are three files that exhibit
the behaviour for me:
API.lhs
=======
> module API where
> data Config = Config { param :: String }
Main.lhs
========
> module Main where
> import System (getArgs)
> import System.Plugins
> import API
> getConfig :: [String] -> IO Config
> getConfig [file] = do
> status <- make file []
> obj <- case status of
> MakeSuccess _ o -> return o
> MakeFailure es -> mapM_ putStrLn es >> error "make failed"
> putStrLn $ "### loading " ++ file
> m_v <- load_ obj ["."] "config"
> putStrLn $ "### checking " ++ file
> val <- case m_v of
> LoadSuccess _ v -> return v
> LoadFailure es -> mapM_ putStrLn es >> error "load failed"
> return val
> main = getArgs >>= getConfig >>= putStrLn . param
CustomConfig.hs
===============
>module CustomConfig where
> import API
> config = Config { param = "Doomed to fail!" }
I compile the above with "ghc --make -o my_program PluginTest.lhs" and
execute with "./my_program CustomConfig.lhs".
Any hints welcome. Thanks,
Bjorn Buckwalter
