Re: Problem with ghc on Windows ME

i am using win2k too. i've forwarded your message to the person with the problem. but we already know that the problem is not restricted to unlit. he cannot compile a simple "hello world" in a plain .hs file (see my first email). is there any way to raise this as a bug so that someone involved with ghc finds a suitable machine and solves the problem? it's not just my client that's having problems - someone else here has reported something similar. sorry if i seem a little frayed, but it's not cool to send software to someone only to find that they can't compile because ghc doesn't work on a platform it is advertised to support. i know that ghc is a largely voluntary effort, but they've still got more resources than me... andrew Derek Elkins said:

the output is enclosed. the problem seems to be temporary files. what would cause that (i've just emailed him to check that the TEMP directory exists)?

The "rawSystem" part is the function GHC uses to execute external programs, see System.Cmd.rawSystem. The error suggests that it can't find unlit.exe. At any rate, I would suggest finding and testing unlit to see if it works directly with the input that GHC provides it. If that works and GHC is capable of compiling the output you at least have a work-around, otherwise you know where the problem is or you're SOL ;) Suffice to say I have not had this problem using the GHC 6.2 binaries on Win2k so I can't recreate it.
