[Nix-dev] bearing on hydra errors

[stewart mackenzie]

Greetings,

I've got hydra compiling this:
https://github.com/fractalide/fractalide/blob/master/default.nix

nix-shell + nix-build has no errors.
When Hydra builds default.nix I get these errors:

```
in job ‘support.genName.overrideDerivation’:
overrideDerivation not yet supported for functors

in job ‘support.buildFractalideContract.override’:
unsupported value: <LAMBDA>

in job ‘support.genName.override’:
unsupported value: <LAMBDA>

in job ‘support.filterContracts’:
unsupported value: <LAMBDA>

in job ‘support.buildFractalideSubnet.overrideDerivation’:
overrideDerivation not yet supported for functors

in job ‘contracts.path’:
unsupported value: [ <CODE> <CODE> ]

in job ‘contracts.fbp_semantic_error’:
unsupported value: [ <CODE> <CODE> ]

in job ‘support.buildRustPackage.__functor’:
unsupported value: <LAMBDA>

in job ‘contracts.fbp_graph’:

in job ‘contracts.file_error’:
unsupported value: [ <CODE> <CODE> ]

in job ‘support.buildFractalideContract.overrideDerivation’:
overrideDerivation not yet supported for functors

in job ‘support.buildRustPackage.override’:

in job ‘support.buildFractalideComponent.__functor’:
unsupported value: <LAMBDA>

in job ‘support.genName.__functor’:
unsupported value: <LAMBDA>

in job ‘contracts.maths_boolean’:
unsupported value: [ <CODE> <CODE> ]

in job ‘support.buildFractalideSubnet.__functor’:
unsupported value: <LAMBDA>

in job ‘support.buildRustPackage.overrideDerivation’:

in job ‘support.buildFractalideComponent.overrideDerivation’:
overrideDerivation not yet supported for functors

in job ‘contracts.fbp_lexical’:
unsupported value: [ <CODE> <CODE> ]

in job ‘support.buildFractalideSubnet.override’:
unsupported value: <LAMBDA>

in job ‘support.buildFractalideComponent.override’:
unsupported value: <LAMBDA>

in job ‘contracts.file’:
unsupported value: [ <CODE> <CODE> ]
```

Now the

`in job 'contracts.X
unsupported value: [ <CODE> <CODE> ]':

errors arises here:
https://github.com/fractalide/fractalide/blob/master/build-support/buildFractalideContract.nix#L32

(the iip bit of the list still has to be completed so it's just a
placeholder, though the contract part of the list is finished.)

What are these errors?
