If I understand you correctly, all you have to do is pass the

Probably a stupid question, but if SDL supplies its own main

While on the subject of GHC's build options, can we change the

Hi all,
I've whipped up an example tarball of how to do "runtime loading"
(similar to dynamic loading, a.k.a. dlopen() or LoadLibrary()) in
GHC. You can find it here:
http://www.algorithm.com.au/wiki/hacking/haskell.ghc_runtime_loading
It's a little example stdin text filter program, that

.. unless you compile it with -O2
Hi all,
I'm trying to get a grip on the Dynamic types stuff supplied with
GHC, and I'm not sure if I'm doing something wrong, or whether
I've found a bug.
It seems that the fromDynamic and fromDyn functions seem to work
if you load your module into GHCI, but they don't work when you
compile it i

Hi all,
Manuel Chakravarty has helped me[1] with getting runtime
importing of modules (a.k.a. dynamic loading) working in GHC on
Linux. It should work on Windows, too.
