Describe the bug
Ormolu.Fixity doesn't compile with cabal build.

Error: cabal-3.10.2.1.exe: Failed to build ormolu-0.7.4.0 (which is required
by exe:ormolu from ormolu-0.7.4.0). The build process terminated with exit

To Reproduce

Run cabal build

Expected behavior

Project compiles.

Environment

  • OS name + version: Windows 10.
  • Version of the code: latest from master branch

Hmm, Ormolu.Fixity uses Template Haskell, maybe that is the culprit:

ormolu/src/Ormolu/Fixity.hs

Line 61 in 7e000cb

BL.fromStrict $(embedFile "extract-hackage-info/hackage-info.bin")

Just to debug: Can you try to replace this line with

    BL.fromStrict ""

just to see whether that allows compilation to succeed?

bjornkihlberg commented

@amesgen Yes, it compiles with your suggested change.

I don't think this is a problem with your project, I think this is a problem with GHC and Windows and it seems to be recurring.

Thanks for confirming! As the problem indeed seems to be independent of Ormolu, I will close this issue then, but in case you find a solution feel free to post it here (maybe other people run into the same thing).

Also just FTR: We have prebuilt Windows binaries on our release page: https://github.com/tweag/ormolu/releases/tag/0.7.4.0
