Wow, it's an impressive amount of work, kudos to you! So far, almost all of the new packages are building successfully on Hydra, but I see one failure: ghc-resourcet, which in turn causes r-bookdown to dep-fail: https://hydra.gnu.org/build/2495799/nixlog/1/raw There are many errors similar to these: --8<---------------cut here---------------start------------->8--- Control/Monad/Trans/Resource/Internal.hs:302:10: error: • Could not deduce (MonadBase IO (Strict.StateT s m)) arising from the superclasses of an instance declaration from the context: MonadResource m bound by the instance declaration at Control/Monad/Trans/Resource/Internal.hs:302:10-63 • In the instance declaration for ‘MonadResource (Strict.StateT s m)’ Control/Monad/Trans/Resource/Internal.hs:303:10: error: • Could not deduce (MonadBase IO (Strict.WriterT w m)) arising from the superclasses of an instance declaration from the context: (Monoid w, MonadResource m) bound by the instance declaration at Control/Monad/Trans/Resource/Internal.hs:303:10-75 • In the instance declaration for ‘MonadResource (Strict.WriterT w m)’ phase `build' failed after 1.5 seconds builder for `/gnu/store/r9mlrjkywz6grnmf84gwmy3ggx1zglkd-ghc-resourcet-1.1.7.5.drv' failed with exit code 1 @ build-failed /gnu/store/r9mlrjkywz6grnmf84gwmy3ggx1zglkd-ghc-resourcet-1.1.7.5.drv - 1 builder for `/gnu/store/r9mlrjkywz6grnmf84gwmy3ggx1zglkd-ghc-resourcet-1.1.7.5.drv' failed with exit code 1 --8<---------------cut here---------------end--------------->8--- Thanks for working on it!
