there SHOULD be a 32bit 7.8.4 build available somewhere for windows, and if not , thats a real problem! I'm gonna shift this thread to ghc-devs, because that *should* get addressed
@ghc-devs, how can we help this user get ahold of a 32bit windows 7.8.4 build? (eg, why do we not have one available yet?) -Carter On Mon, Mar 9, 2015 at 4:13 AM, Kees Bleijenberg <[email protected] > wrote: > Thanks for your answer. > > I also use ghc to create 32 bits dll’s. 7.8.4 is 64 bits GHC and can’t > create 32 bits dll’s (?).
