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. -- System Information: Debian Release: wheezy/sid APT prefers raring-updates APT policy: (500, 'raring-updates'), (500, 'raring-security'), (500, 'raring') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.8.0-19-generic (SMP w/4 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages ghc depends on: ii gcc 4:4.7.3-1ubuntu10 ii libbsd-dev 0.4.2-1ubuntu1 ii libc6 2.17-0ubuntu5 ii libc6-dev 2.17-0ubuntu5 ii libffi-dev 3.0.13-2ubuntu1 ii libffi6 3.0.13-2ubuntu1 ii libgmp-dev 2:5.0.5+dfsg-2ubuntu3 ii libgmp10 2:5.0.5+dfsg-2ubuntu3 ii libtinfo5 5.9-10ubuntu4 ghc recommends no packages.
