I also ran into this problem while trying to install clock-0.8.2 on an M1 Mac with GHC 9.2.1. How did you solve this problem?

I've also had this same issue, I realise it might not be strictly related to 'clock', but what was the solution?

[arafangion]

Ah, found it. @tfausak, this appears to be https://gitlab.haskell.org/ghc/ghc/-/issues/20592 (Definitely not clock here!)

The fix mentioned in that ticket works for me.

Thanks for connecting the dots there @arafangion! I can confirm that the solution proposed in this comment fixed the problem for me. To make that concrete, here's what was failing for me:

uname -a
# Darwin TayMini.local 21.1.0 Darwin Kernel Version 21.1.0: Wed Oct 13 17:33:24 PDT 2021; root:xnu-8019.41.5~1/RELEASE_ARM64_T8101 arm64

ghcup --version
# The GHCup Haskell installer, version v0.1.17.4

~/.ghcup/bin/ghc-9.2.1 --version
# The Glorious Glasgow Haskell Compilation System, version 9.2.1

~/.ghcup/bin/cabal-3.6.2.0 --version
# cabal-install version 3.6.2.0
# compiled using version 3.6.2.0 of the Cabal library

~/.ghcup/bin/cabal-3.6.2.0 build --with-compiler ~/.ghcup/bin/ghc-9.2.1

And doing this instead succeeded:

# note this is fish shell
env C_INCLUDE_PATH=(xcrun --show-sdk-path)/usr/include/ffi \
  ~/.ghcup/bin/cabal-3.6.2.0 build --with-compiler ~/.ghcup/bin/ghc-9.2.1
