GHC 7.10.3 works fine for me when I use the hvr ppa https://launchpad.net/~hvr/+archive/ubuntu/ghc

Hi,

I'm trying to use GHC 7.10.2 (the Debian 8 bindist from haskell.org) on Ubuntu
18.04. It's currently failing with linker errors when I compile `main = return
()`:

    /usr/bin/x86_64-linux-gnu-ld:
/home/omer/ghc_bins/ghc-7.10.3-bin/lib/ghc-7.10.3/base_HQfYBxpPvuw8OunzQu6JGM/libHSbase-4.8.2.0-HQfYBxpPvuw8OunzQu6JGM.a(Base__5.o):
relocation R_X86_64_32S against `.text' can not be used when making a
PIE object; recompile with -fPIC
    /usr/bin/x86_64-linux-gnu-ld:

relocation R_X86_64_32S against symbol `stg_bh_upd_frame_info' can not

I'm getting about 700 of these. Does anyone know a way to make GHC 7.10.2 work
on Ubuntu 18.04? Not sure if related but the ld version is

    ~ $ /usr/bin/x86_64-linux-gnu-ld --version
    GNU ld (GNU Binutils for Ubuntu) 2.30
