ghci panic
Hi, I got the following panic message when trying to load haven into ghci, and the panic message said that I should report the problem, so here you go. :) I am using ghc 5.02.1 under Windows 2000 / Cygwin. I'd really like to be able to use ghci for Haven development, so any ideas on what might be causing this would be most welcome. I'd be happy to make the exact setup available if you'd like to reproduce the bug yourselves. -antony $ ghci HavenTest ___ ___ _ / _ \ /\ /\/ __(_) / /_\// /_/ / / | | GHC Interactive, version 5.02.1, for Haskell 98. / /_\\/ __ / /___| | http://www.haskell.org/ghc/ \/\/ /_/\/|_| Type :? for help.

Any idea what's wrong?

Re: ghci panic (unknown symbol stg_gc_l1)
Hi,
GHCi doesn't load the RTS package (nor GMP),
as they're both baked into the binary. My guess is that
you've built ghci using 5.02.1; you need to use 5.02.2
(i.e., do two stage build.) The missing symbol was
introduced in 5.02.2's RTS.
