Re: GHC 6.4.2 on OS X

[Peter Gammie]

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:

ghc-6.4.2: unable to load package `cudd-0.3.0'


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.)

Re: [Haskell] GHC Hackathon

[Malcolm Wallace]

  I think many would be grateful if a podcast were made of this event
  such that those who missed it can still watch the presentations.
 
 +1. A podcast would be perfect, posting minutes would be next in line.

If the Hackathon goes ahead, recording a video podcast of the event
should be straightforward.  (I've been playing with streaming web media
lately, and can volunteer to do that side of things.  The quality can be
surprisingly good.)  Mind you, even the compressed web streams will not
be small - approx 150Mb per hour.  A one day tutorial could easily
stretch to over 1Gb.

Regards,
Malcolm
