GHC 9.4.1 is now available!

Announcements
#21

8.10.7 is still considered the “recommended” version, as you can verify by running ghcup tui.

“ghc --version” still gives 8.10.2

Perhaps you want ghcup set ghc 9.4.1?

Looks like GHC 9.4.1 doesn’t install the HsFFI.h header file in the same place as usual -

vanessa@vanessa-desktop ~/programming 🌸 fd HsFFI.h ~/.ghcup/ghc/
/home/vanessa/.ghcup/ghc/9.0.2/lib/ghc-9.0.2/include/HsFFI.h
...
/home/vanessa/.ghcup/ghc/9.4.1/lib/ghc-9.4.1/lib/x86_64-linux-ghc-9.4.1/rts-1.0.2/include/HsFFI.h
...
/home/vanessa/.ghcup/ghc/9.2.4/lib/ghc-9.2.4/include/HsFFI.h

Maybe missing a symlink?

Vanessa, are you directly depending on the headers? The include directory was removed from the bindist in the 9.4 series as you should use ghc-pkg to determine the location of headers for the rts package.

Oh I see! Never mind then, that works well :slight_smile:
