#12755: Build from source fails on Ubuntu 16.10: ld: -r and -pie may not be used together -------------------------------------+------------------------------------- Reporter: SamuelMarks | Owner: Type: bug | Status: closed Priority: high | Milestone: 8.0.2 Component: Build System | Version: 8.0.1 Resolution: duplicate | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Building GHC | (amd64) failed | Test Case: Blocked By: | Blocking: Related Tickets: #12759 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by bgamari): * status: new => closed * resolution: => duplicate * related: => #12759 * milestone: => 8.0.2 Comment: The problem here is that we pass `-Wl,-r` to `gcc` when joining object files and linking libraries. This is incompatible with the implicit `-pie` which the affected gcc versions assume. It turns out that GCC 6 has a `-r` flag which we could use in place of `-Wl,-r` and would do the right thing. Unfortunately it is undocumented so I'm rather reluctant to depend upon it. Really I suspect the correct solution here is to simply use `ld` directly for everything except for the final link (since linking an executable will likely require linking against `libgcc`). However, this is out of scope for 8.0.2. Consequently, I think the next best solution is to simply ensure we pass `-no-pie` to `gcc` when we do not intend on linking an executable. I have done exactly this in Phab:D2691 which has been merged to `master` (bae4a55b1fb403f610b4b55a1b6fb3f03e9c2026) and `ghc-8.0` (). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12755#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
