Hello,
OK, if GHCi's linker can't cope with the extra symbols, then perhaps
we can get rid of them.
Following the advice here:
http://lists.apple.com/archives/scitech/2005/Sep/msg00019.html
I built my GHCi .o file like so:
GHCI_LD_OPTS += -L/usr/lib/ -lSystemStubs
...
$(LD) $(GHCI_LD_OPTS) -o h$$lib.o $(CUDD_LIB)/$$lib/lib$$lib.a;\
err... you get the idea: add that bit of linker magic to whatever
you're already doing and those nasty symbols go away. I don't know if
this is a general fix but it works for me.
cheers

Hello,
I am wondering if the following patch (or equivalent) made it into
GHC 6.4.2. I was hoping it would fix my problem:
mjollnir ~/src/ghc/ghc-6.4.2$ ghci `hbdd-config --cudd-libs`

It is a problem with GCC 4.0 and GHCi - GHC works fine.

Can you give me some idea how to fix it? (The use of fprintf is
inessential for my purposes but I'd prefer not to hack the C
library too much.)
