#10376: arm/linux linking failure -------------------------------------+--------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: arm Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: #10464 | Differential Revisions: -------------------------------------+--------------------------------- Comment (by k-bx): Steps to reproduce in case you don't have an access to an ARM machine: 1. Get a $3.40/month [http://techcrunch.com/2015/09/02/scaleway-now- provides-crazy-cheap-virtual-private-servers-starting-at-3-40-per-month/ dedicated ARM server] (sorry if it sounds like an ad) 2. Install [https://packages.debian.org/experimental/armhf/ghc/download GHC from debian experimental] 3. {{{ # uname -a Linux arm 4.1.6-249 #1 SMP Mon Aug 31 12:34:47 UTC 2015 armv7l armv7l armv7l

quite painful, especially on real- world projects like the ones using yesod, there's just too much output like this. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10376#comment:2 GHC
