Re: Superclasses

[Edward Kmett]

I'm rather incapacitated at the moment as I just got out of major surgery,
so I'm not in a good place to check particulars right now.

I can definitely say I'd like some way to attain an equivalent result, but
I accept that it may not be possible with the machinery we have.

MSYS2 update (those who build on Windows please read)

[Phyx]

Hi Windows devs,

February comes with a major change in behavior for MSYS2/Cygwin.
Tools such as awk/sed etc now use binary mode unless on a text mount:
https://cygwin.com/ml/cygwin-announce/2017-02/msg00036.html

This is problematic because GHC etc only use the underlying OS to determine
how to output line endings. As such we output \r\n but in sed et al $ will
no longer match line endings. Which means out scripts are currently broken.

Do not upgrade your MSYS2 install until a workaround for this is in place
or you will be unable to compile GHC.

If you have updated your MSYS2 then using a text mount may be the easiest
option to get a working build again. As it seems just downgrading the tools
alone is not enough.

Thanks,
Tamar

In comment:23 of https://ghc.haskell.org/trac/ghc/ticket/11523 I claim that 
there is an infinite tower of superclasses, so that GHC can legitimately spin.
You have not responded for nearly a year.
Do you agree?
