Error compiling tcIfaceGlobal not found

[pawel-tomkiel]

Hi,

When i try to go step by step on ArchLinux I got:

[257 of 295] Compiling GI.Gio.Interfaces.File ( GI/Gio/Interfaces/File.hs, dist/dist-sandbox-a7e8621a/build/GI/Gio/Interfaces/File.o )
ghc: panic! (the 'impossible' happened)
  (GHC version 8.2.2 for x86_64-unknown-linux):
    tcIfaceGlobal (local): not found
  You are in a maze of twisty little passages, all alike.
  While forcing the thunk for TyThing IsFile
  which was lazily initialized by initIfaceCheck typecheckLoop,
  I tried to tie the knot, but I couldn't find IsFile
  in the current type environment.
  If you are developing GHC, please read Note [Tying the knot]
  and Note [Type-checking inside the knot].
  Consider rebuilding GHC with profiling for a better stack trace.

Hello @neonkowy,

There is a problem with an upstream package when using GHC 8.2.X. If you can configure Haskell Stack to use GHC 8.0.2, Gifcurry will build.

You can avoid building Gifcurry though by downloading the AppImage or the prebuilt binaries for linux.

If you use the AppImage, make sure to right click on the AppImage and allow the file to be executed as a program.

I'll have to push a fix to force stack to choose GHC 8.0.2 when building Gifcurry.

Hello @neonkowy,

I have updated the Arch AUR package. It should install now.
