Re: docker GHC image for hacking

2014-12-08 Thread Sean Seefried
I came to a similar conclusion. I recently put together a Dockerfile that builds GHC 7.8.3 as an ARM cross compiler https://github.com/sseefried/docker-build-ghc-android I've also written a draft blog post about it. It might contain some inaccuracies but any feedback is welcome. (Please send to m

Friends, As someone who started hacking on GHC last month I wanted to tell you that there is to high an overhead to getting started and overall to contributing to GHC. One thing that can help is to make getting to the point of compiling GHC a much faster experience rather than starting off by dre

FWIW, Herbert and I managed to pin down part of this to Simon's machine; for some reason he's unable to contact the machine via IPv6 which his machine defaults to (neither I nor Herbert could reproduce this); in the mean time, IPv4 appears fine. On Mon, Dec 8, 2014 at 11:54 AM, Jan Stolarek wrote
