Package: ghc
Version: 7.6.2-1ubuntu1
Severity: normal
I want to compile a simple Haskell program:
$ git clone git://github.com/jgoerzen/twidge.git
$ ghc --make -o setup Setup.lhs
[1 of 1] Compiling Main ( Setup.lhs, Setup.o )
Linking setup ...
/usr/bin/ld.bfd.real: Setup.o: relocation R_X86_64_32S against
`stg_CAF_BLACKHOLE_info’ can not be used when making a shared object; recompile
with -fPIC
Setup.o: could not read symbols: Bad value
collect2: error: ld returned 1 exit status
Oops! So, after a bit of searching, I tried:
$ ghc --make -dynamic -o setup Setup.lhs
[1 of 1] Compiling Main ( Setup.lhs, Setup.o )
Linking setup ...
/usr/bin/ld.bfd.real: Setup.o: relocation R_X86_64_PC32 against undefined
symbol `newCAF’ can not be used when making a shared object; recompile with
-fPIC
/usr/bin/ld.bfd.real: final link failed: Bad value
Oops! More searching leads me to this ancient mailing list message:
http://www.haskell.org/pipermail/glasgow-haskell-users/2004-May/006597.html
but no further clues I can translate into workarounds. I can't find a
README.Debian explaining this problem, but without further evidence,
it doesn't seem to be a GHC bug.
I presume there is a workaround; it would be lovely to know what it is.
(Disclosure: I used to be on the GHC team! A very long time ago,
though. And I mostly worked on the Windows port.)
I am using Ubuntu, but the only change in the Ubuntu packaging is to
disable GHCi on ARM (a change since adopted upstream), so I'm fairly
confident this problem manifests on Debian x86_64 too.
