I've filed bug reports for the broken packages: haskell-pkg-janitors/unix-compat#13, UnkindPartition/ansi-terminal#173, corsis/clock#92

Thanks for the report @clin1234 !

This is a common problem with haskell tools. They need a suitable locale configured.
See also https://hledger.org/install.html#text-encoding. I see the windows doc link has broken, but perhaps this gives you ideas ?

[simonmichael]

I read that this might help in powershell:

$env:LC_ALL = "C.UTF-8"
$env:LANG = "C.UTF-8"

or this in CMD:

set LC_ALL=C.UTF-8
set LANG=C.UTF-8

There are also lots of ways to get pre-built binaries for Windows, if you don't need to build your own: https://hledger.org/install.html

I can report that installing via cabal uses the latest GHC 9.10.1 compiler, and doesn't error at all.

[simonmichael]

@clin1234 good news. If you have time for additional testing that would be helpful:
Does it also build with stack when using the GHC 9.10 toolchain ?

stack --snapshot nightly-2024-12-12 install hledger

[clin1234]

Works, no errors
