GHC 7.10.3 does not compile on NixOS

    • Closed Issue created by waern @trac-waern

    Building GHC 7.10.3 in Nix on Linux currently fails with linker errors. https://github.com/NixOS/nixpkgs/issues/10752 has further details.

    The problem goes away if one reverts GHC commit 296bc70b.

    I don't know what the issue is, and I can't be 100% sure it's really a GHC problem and not a Nix one, but I thought it best to record this here.

      Hmm, can you attach config.log from your installation attempt? I wonder whether configure is finding librt.

      Can someone distill from the Github issue a concise set of instructions to reproduce this issue? I have installed nix but it's totally unclear to me how to reproduce this. At the moment I have,

      $ cd ~/ghc/ghc
$ nix-shell -Ahaskell.packages.ghcHEAD.ghc '<nixpkgs>'
error: Package ‘VisualBoyAdvance-1.7.2’ in ‘/nix/store/p1jp78n8mmk5sj9wpz5hf5jk8x8zqcdy-nixpkgs-16.03pre71923.3087ef3/nixpkgs/pkgs/misc/emulators/VisualBoyAdvance/default.nix:18’ is marked as broken, refusing to evaluate.
For `nixos-rebuild` you can set
  { nixpkgs.config.allowBroken = true; }
in configuration.nix to override this.
For `nix-env` you can add
  { allowBroken = true; }
to ~/.nixpkgs/config.nix.

      We have the exact same issue with GHC 7.10.3. See http://hydra.cryp.to/build/1411032/log/raw for a complete build log. Run

      nix-build ~/src/nixpkgs -A haskell.compiler.ghc7103

      to re-produce, where ~/src/nixpkgs refers to a recent checkout of the Nixpkgs master branch.

      It seems like ./configure detects the presence of librt, so features that depend on it are enabled, but the library is never actually linked. This issue is rather serious for us, because it prevents us from updating to GHC 7.10.3 on NixOS, i.e. we can no longer support upcoming versions of LTS Haskell without a fix for this problem. Any suggestions how to fix or work aroung this phenomenon are very welcome.

      It's not librt that isn't being linked, it's libpthread. The eventual issue is here:

/nix/store/5kdjp8200hazaydx0dmwn5qghqkyi3py-binutils-2.23.1/bin/ld: warning: libpthread.so.0, needed by /nix/store/483br9kb3f5igsgmb6aqsjhl2ipj2bxr-glibc-2.21/lib/librt.so, not found (try using -rpath or -rpath-link)

      On my working system, utils/hsc2hs/dist-install/build/tmp/hsc2hs is built with the option -optl-lpthread also, which is missing from the above command line.

      This flag comes from the extra-libraries field of the unix package, which is populated from the configure variable EXTRA_LIBS via libraries/unix/unix.buildinfo.in. On my system pthread is added to that variable by this from configure.ac:

      AC_SEARCH_LIBS(sem_close, pthread,
    [EXTRA_LIBS="$EXTRA_LIBS $ac_lib"],
    [AC_MSG_NOTICE([Not found])])

      but in your libraries/unix configure output I see

      checking for library containing sem_close... none required

      so that explains why later -optl-pthread is not provided when building utils/hsc2hs/dist-install/build/tmp/hsc2hs.

      I don't understand why on your Nix system configure apparently detected that -lpthread is not needed for the symbol sem_close. Apparently it was wrong about that. I also have no idea what this has to do with the commit that apparently broke things for you. (I am building the tip of the ghc-7.10 branch, so I also have that commit.)

      A NixOS user has indicated that master works fine and the issue has been patch. Apparently the problem was due to an interaction with NixOS's GCC wrapper,
