Re: GHC 6.4.2 on OS X

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 peter On 26/04/2006, at 10:00 PM, Peter Gammie wrote:

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:

...

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.)
