‘Streamly.Internal.FileSystem.Event.Darwin’ does not export ‘Event’ #2595

Closed o1lo01ol1o closed 11 months ago

I'm compiling streamly 0.9 on an apple M2 under nix and it looks like theres a combination of flags that is incorrect somewhere:

[63 of 72] Compiling Streamly.Internal.FileSystem.Event ( src/Streamly/Internal/FileSystem/Event.hs, dist/build/Streamly/Internal/FileSystem/Event.o, dist/build/Streamly/Internal/FileSystem/Event.dyn_o )

src/Streamly/Internal/FileSystem/Event.hs:54:51: error:
    Module
    ‘Streamly.Internal.FileSystem.Event.Darwin’
    does not export
    ‘Event’
   |
54 | import Streamly.Internal.FileSystem.Event.Darwin (Event)

Is there a quick workaround?

Ah: the actual error was higher in the log:

src/Streamly/Internal/FileSystem/Event/Darwin.hs:1079:2: error:
