Hello, short followup, when I also removed Cabal from libraries/Makefile SUBDIRS, then the build has gone well and I'm able to compile and run simple Haskell testing programs. Great work, indeed! I'm looking forward to seeing LambdaVM merged to the standard GHC. Thanks! Karel Karel Gardas wrot

LambdaVM: build fails on Solaris/x86

2009-01-13 Thread Karel Gardas
Hello Brian and All, I'm curious if anyone here attempted building LambdaVM on non-GNU system. I'm using OpenSolaris/x86 and build fails with: == Recursively making `depend' for ways: '' ... PWD = /export/home/karel/vcs/lambdavm/libraries/Cabal ---

I reproduced the error on my setup (GHC 6.10.1 on WS2003), and received SEH exception 0xC0FD, which is STATUS_STACK_OVERFLOW "A new guard page for the stack cannot be created". It looks like something is overflowing the OS stack or improperly bumping the guard page at the end of the allocated s

RE: [Haskell] type family vs. polymorphism

2009-01-13 Thread Simon Peyton-Jones
[Redirecting to GHC users] Andres, Nice example. It's another instance of a problem that keeps coming up with type families. Details here: http://hackage.haskell.org/trac/ghc/ticket/1897#comment:10 The rest of the ticket gives other examples. It's not clear what the Right Thing to do is.

RE: Differences in pattern matching syntax?

2009-01-13 Thread Simon Peyton-Jones
I agree that's odd. Are you using -O? Can you give us a reproducible test case? (The only think I can think is that the line |Gc{} -> Tm (grspe r) will build a thunk for (grspe r), and depending on the context I suppose you might get a lot of those.) Thanks Simon | -
