Hi,
Building GHC HEAD in Nix on Linux currently fails with linker errors. See https://github.com/NixOS/nixpkgs/issues/10752
The problem goes away if one reverts GHC commit 296bc70b5ff6c853f2782e9ec5aa47a52110345e.
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.
New description: 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 296bc70b5ff6c853f2782e9ec5aa47a52110345e. 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. -- Comment: 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. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11147#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
