c2hs error when installing #11

Closed lebensterben closed 3 years ago

I first tried to install this package via cabal, it shows error with c2hs.

Then I pulled the latest commit, and run cabal build,

  The character '#' does not fit here.

If I go to Sound/ALSA/Mixer directory and manually run c2hs Internal.chs it throws the same error.
