Hi Simon,

You need

export MSYSTEM=MINGW64

in your bash profile.

I’ve just got  a new laptop (the old one’s hard disk died) so I’m trying to get to the point of being able to build GHC again.

I’m currently stuck here:

./configure

configure: loading site script /usr/local/etc/config.site

checking for gfind... no

checking for find... /usr/bin/find

checking for sort... /usr/bin/sort

checking for GHC version date... inferred 8.5.20180323

checking for GHC Git commit id... inferred affdea82bb70e5a912b679a169c6e9a230e4c93e

checking for ghc... /c/fp/HP-8.2.2/bin/ghc

checking version of ghc... 8.2.2

GHC path canonicalised to: c:/fp/HP-8.2.2/bin/ghc

checking build system type... x86_64-pc-msys

checking host system type... x86_64-pc-msys

checking target system type... x86_64-pc-msys

Unknown OS msys

Any ideas?

Thanks

Simon
