Bug Description

haskell-devscripts or GHC invokes non-PIC compilation followed by PIC linking, leading to linker errors on amd64 and armhf in the other packages listed in this bug. This is blocking the pandoc source package from migrating to the release pocket (bug #1982460).

For example, haskell-diff fails to build in kinetic-proposed only on amd64, with the following error (https://launchpad.net/ubuntu/+source/haskell-diff/0.4.1-1/+build/23854045):

/usr/bin/ld.gold: error: dist-ghc/build/Data/Algorithm/Diff.dyn_o: requires dynamic R_X86_64_PC32 reloc against 'Diffzm0zi4zi1zm1zzL3fycaRHO4aduijwvx7f_DataziAlgorithmziDiff_Both_con_info' which may overflow at runtime; recompile with -fPIC
/usr/bin/ld.gold: error: dist-ghc/build/Data/Algorithm/DiffOutput.dyn_o: requires dynamic R_X86_64_PC32 reloc against 'Diffzm0zi4zi1zm1zzL3fycaRHO4aduijwvx7f_DataziAlgorithmziDiffOutput_LineRange_con_info' which may overflow at runtime; recompile with -fPIC

Hello, I uploaded in my ppa a haskell-devtools with hlibrary.mk patched this way

export DEB_LDFLAGS_MAINT_STRIP=-Wl,-Bsymbolic-functions

and now everything looks good again (except for some haskell libraries needing lto disabled too)

What is your proposed solution? enable PIC in devtools?

My proposed solution is to enable -fPIC in haskell-devscripts, to enhance security of Haskell code.

Hello Luis, do you have a patch for this? All my attempts failed...

As no patch has been forthcoming to fix this to use -fPIC, I have uploaded Gianfranco's patch to disable -Wl,-Bsymbolic-functions so that we can move the haskell transition forward for kinetic.
