Don,
thanks for your answers - that looks very promising.
Only as these are the systems that I've tested on, or that others have. I don't have access to a Windows machine. hs-plugins should only be limited to platforms with a working GHC dynamic loader, which is all the systems I've tested on, plus Windows. Any unixy dependencies should be considered bugs, and will be removed as I find them.
ah well, you do depend on a unixy build environment;-) I've got cygwin myself, but I can't rely on my users having such things. More seriously, though:
a cursory browse of the sources shows up things like "POpen" and "Posix", both no-nos, as far as portable ghc code is concerned (no longer supported in the default ghc for windows, AFAIK). it would be good if ghc-users would keep that in mind when writing portable Haskell code.
Ah. Good point. Well, it is portable to everything except windows, right ;)
if you really need pipes to subprocesses, there's an apparently portable implementation in wxhaskell (Graphics.UI.WXCore.Process, no graphics needed - wxhaskell has lots of non-graphics widgets), or the up-and-coming System.Process. don't know about the rest of the Posix modules..
i don't have much time for testing right now, and "configure;make" stalls early on with a rather strange-looking message (see below), so I'll probably
Hmm. Strange. I don't have any ideas about this at the moment.
have to leave that till next month. but, as i mentioned, i need something like this, and if the idea is to provide a higher-level API on top of -package ghc, that sounds like a good way to go.. provided that the unix-"bugs" don't stop the show.
Certainly. I'll look into this. Thanks for pointing it out! -- Don
