[jhc] Compiling bytestring in jhc

[Nawal Husnoo]

Hi,

I'm trying to compile bytestring using JHC, but I'm getting an error:

Why:     context reduction, no instance for: Jhc.Class.Ord.Eq
(Jhc.ForeignPtr.ForeignPtr Jhc.Type.Word.Word8)

Any ideas?

jhc -V
jhc 0.8.2 (mydniquipepo-32)
compiled by ghc-7.8 on a x86_64 running darwin


Thanks,

Nawal.
