souurce for old version of libffi

souurce for old version of libffi

[tim.beech]

I'm packaging GHC (Glasgow Haskell Compiler) for Salix, a Slackware
derivative, and it depends on old versions of libgmp and libffi.

Specificaly, it is looking for /usr/lib/libffi.so.3
and finding libffi.so.6

These numbers don't seem to correspond to the version numbers for
libffi; as far as I know, the latest libffi for Slackware is
libffi-3.something.

I've searched without success. I'd be extremely grateful if anyone could
point me in the direction of a tarball.

I'm sorry to say I got my wires crossed. ghc does indeed require an
earlier version of libffi, but the previous one will do. It's
libffi.so.5 it's looking for. I got muddled because of a similar
problem with another library.

Please, don't do this.  Let's fix GHC.  I may be able to help.

I believe this is the link you are looking for:

http://hackage.haskell.org/trac/ghc/ticket/5743
http://bugs.gentoo.org/show_bug.cgi?id=411925 (downstream bug linking to 
the above bug)

The problem was that the bundled libffi conflicted with the system 
libffi, as in, both got picked up one way or another

Yes, that looks like it.  AFAIK most distros won't allow packages to
bundle magic library versions anyway.

Yes, I see.
