[Haskell-cafe] Start GHCI with a static library

[Christopher Allen]

You need a GHC built for this, I think.

Using this setup:

https://ghc.haskell.org/trac/ghc/ticket/5371


[callen at atlantis ~/Work/exist]$ ghci -L. -lfoo testlink.hs
GHCi, version 7.10.1: http://www.haskell.org/ghc/  :? for help
ghc: panic! (the 'impossible' happened)
  (GHC version 7.10.1 for x86_64-unknown-linux):
Loading archives not supported


[callen at atlantis ~/Work/exist]$ /opt/ghc/7.6.3/bin/ghci -L. -lfoo
testlink.hs
GHCi, version 7.6.3: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading object (static archive) ./libfoo.a ... done
final link ... done
[1 of 1] Compiling TestLink         ( testlink.hs, interpreted )
Ok, modules loaded: TestLink.
Prelude>
Leaving GHCi.


[callen at atlantis ~/Work/exist]$ /opt/ghc/7.8.4/bin/ghci -L. -lfoo
testlink.hs
GHCi, version 7.8.4: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading object (static archive) ./libfoo.a ... ghc: panic! (the
'impossible' happened)
  (GHC version 7.8.4 for x86_64-unknown-linux):
Loading archives not supported

(ditto 7.8.3)

https://mail.haskell.org/pipermail/glasgow-haskell-users/2014-October/thread.html#25338

Respective versions of GHC are all from hvr's Ubuntu PPA.

These are the versions I have installed:

ghc-7.10.1 install
ghc-7.6.3 install
ghc-7.8.3 install
ghc-7.8.4 install


Afraid I don't know much about linkers or GHC dev so that's I all I can do
for you at this time.

Cheers,
Chris
