[wxhaskell-devel] darcs patch: (OS X) Skip intermediate step of compiling master.o (r...

[Eric K. <eri...@gm...>]

Hi shelarcy and list,

Any thoughts on this patch?  I realise it undoes your partial undo, but
maybe new build data from Malcolm might give us a clue where to go.
Interestingly, it looks like like --enable-shared is the right way to
go, and not --disable-shared like we have traditionally been telling
everyone (I don't fully understand why either way).  If this is so, all
the better, I guess since --enable-shared tends to be default (?)

  I'm going to quote some mails from Malcolm Wallace on wxhaskel-users in early
