Nix releases are failing to build
rihardsk opened this issue · comments
Recently i wanted to try out funflow using nix, but it failed to build. The build jobs on nixpkgs's hydra build server are failing as well https://hydra.nixos.org/job/nixpkgs/trunk/haskellPackages.funflow.x86_64-linux
I can provide you with build error outputs that nix is producing if you wish (after a while when i have some time).
Or is this something i should report in the nixpkgs github?
I imagine this is because the testsuite fails because it relies on some external processes. There are no longer any logs on hydra though to verify this.
Building this and taking a look now...
Here's the output of building a simple project with funflow
as the only dependency
/home/nc/topos/pfizer/funflow/funflow/src/Control/Funflow/Exec/Simple.hs:152:11: error:
* Could not deduce (Control.Monad.Fail.MonadFail m)
arising from a do statement
with the failable pattern `KnownTask _'
from the context: (Coordinator c, Exception ex,
MonadBaseControl IO m, MonadMask m, KatipContext m)
bound by the type signature for:
runFlowEx :: forall (m :: * -> *) c (eff :: * -> * -> *) ex a b.
(Coordinator c, Exception ex, MonadIO m, MonadBaseControl IO m,
MonadCatch m, MonadMask m, KatipContext m) =>
c
-> Config c
-> CS.ContentStore
-> (eff ~> AsyncA m)
-> Int
-> Flow eff ex a b
-> a
-> m b
at src/Control/Funflow/Exec/Simple.hs:(53,1)-(65,16)
or from: b1 ~ CS.Item
bound by a pattern with constructor:
External :: forall a (eff :: * -> * -> *).
ExternalProperties a -> (a -> ExternalTask) -> Flow' eff a CS.Item,
in an equation for runFlow'
at src/Control/Funflow/Exec/Simple.hs:121:18-38
Possible fix:
add (Control.Monad.Fail.MonadFail m) to the context of
the type signature for:
runFlow' :: forall a1 b1.
So this is to do with newer versions of GHC requiring MonadFail
. I'll push a fix for this.
