(see http://research.microsoft.com/users/t-simonm/ghc/download_ghc_402.html) I know, SPJ got fed up with all the reports so he added a note. You can also get things to compile with GhcHcOpts += -optCrts-M100m which just ups the heap limit to 100Mb! But I imagine the solution posted is probably more sensible. I have made no progress with GHC compiling, the hsc that's built dies in fflush (in the supplied binary RTS). I'm considering taking a binary editor (ah, the memories of svgalib) to that file given that the call is apparently redundant. So what's NOP in Intel asm? :) I have posted a bug against libc6, it looks like it may be related to the IO problems people were having with C++ (null pointer when trying to call the sync method associated with an io stream, in my case). It may just require a recompile of the RTS. I did try using the built RTS instead of the supplied one, but it didn't work properly. Giuliano.

I'd like to apply to become a Debian maintainer and package it, if no one want to take it. Well, for about the fifth time over the years, I'm having a go at compiling ghc (I finally have plenty of disk and a decent amount of RAM). I've hit two problems so far: a) happy is unhappy [1] I have mailed Simon M? regarding this. Binary is distributed for use with libc5, source is distributed with a libc5-dependent bootstrap. I couldn't compile from the source due to ghc being unhappy with the options happy wanted (-fhaskell-1.3) and various hard-codings of the ghc path and the ghc version. I would happy to take on happy, once it's happy. This may just be a case of the GHC people making their latest CVS snapshot available. Oh, and there is the small question of the lack of a licence (I also queried this). b) ghc runs out of heap compiling its parser The file ParseIface.hs (in ghc/compiler) needs more than 64M but no more than 128M of heap to compile. With 64M of RAM and not too much else (X and ntpd) running you are looking at 1500+ garbage collections for about 1.5G of allocation. This file took 10-20 minutes on my machine. If you have 64M of RAM you should probably be the maintainer. I'm thinking of upgrading in the next month of so, funds permitting. In any case, given the quantity of stuff that makes up ghc (the compiler, the profiling tools, the parallel simulation package, etc.), some division of labour might be sensible. If that turns out to be a bad idea... well, I have an alpha on which I could _try_ to get ghc up and running, presupposing a diff.gz and a working bootstrap compiler. I would need to find some more memory for the poor thing though. Lastly, the ghc-users list seems to be rather quiet, but I've only just subscribed. Giuliano. [1] note for the bemused: happy is a yacc for Haskell
