Greetings, now I have a working plugins package, I can refocus on my lambdabot problem. Let me recap: In Lib/Parser.hs, as_name &c are defined #if __GLASGOW_HASKELL__ > 606, however ghc-6.6.1 defines that as 606, so to go through the build, I had to change the '>' to '>='. Is that a bad idea? (otherwise that should be changed in Parser.ly/.hs) Next, in scripts/ShowQ.hs, there is defined an instance (Arbitrary a) => Arbitrary (Maybe a), but such an instance already is defined in Test.QuickCheck, so I commented the one in ShowQ out (after the build died there once). That probably should be fixed in the darcs repo. As anything of the above stupid/dangerous? Okay, so building succeeds without complaints, but then $ ./lambdabot Initialising plugins ................Speicherzugriffsfehler Changing BotPP so that it created a persisting copy of its output, I found out what modulesInfo does, then, letting ircInstallModule produce debugging output, I located the evildoers. lambdabot segfaulted when installing Fact Haddock Quote Source Todo Where What's special about them? I.e., why did they cause a segfault and the others not? And, how could I build a lambdabot _with_ them (though I'm not sure, I'll actually want them, but I might). Without these, I now have an apparently working lambdabot, well, not properly working. First time I started it, all seemed well, but from then on: $ ./lambdabot Initialising plugins ..................................sending message to bogus server: IrcMessage {msgServer = "freenode", msgLBName = "urk!<outputmessage>", msgPrefix = "", msgCommand = "NAMES", msgParams = [""]} ............... done. Main: caught (and ignoring) IRCRaised Data.ByteString.index: index too large: 0, length = 0 lambdabot> > 3+7 Main: caught (and ignoring) IRCRaised Data.ByteString.index: index too large: 0, length = 0 10 lambdabot> The bogus message thing also appeared the first time, I hope this is meant to be so. But what about the ByteString.index exception? Where might that come from? How to get rid of it? Finally, is there a tutorial/manual for using lambdabot? Thanks for any help, Daniel
