This is a problem with the upstream package (it failed to include that file), and has already been fixed in the 0.2.3.2 release; so once the haskell package set is updated this will go away.

I think @peti is producing an updated package set for 17.03 right now, but perhaps there will be an update to unstable before long. In the meantime you could override doCheck.

[peti]

We haven't updated yet, because LTS Haskell hasn't updated yet. :-/

I committed peti@6f0ebfd to remedy that situation. It will land on master in a day or two.

0.2.3.2 also fails to build, the test suite builds but fails with an error. It might be because GHCs >= 8.0 aren't officially supported by the project according to their README. The tests pass when building with ghc7103.
Versions of the package prior to 0.2.3.1 didn't contain a test suite.

[peti]

Is upstream aware of these issues?

[pbogdan]

They are.

[pbogdan]

Investigated a bit more and relayed the details to upstream in DanielG/ghc-syb#20 As noted on that issue I don't know what a proper fix might consist of but hopefully someone more knowledgeable will, and this will get addressed upstream.

[peti]

I'll disable the test suite for GHC 8.x. That will make the build succeed.

[sfultong]

How did this get into 17.03? Doesn't travis run before merges?

[peti]

@sfultong, we have build instructions for 11,881 Haskell packages and nobody is getting paid to make sure they all compile ...

[sfultong]

@peti Sorry, I didn't mean to be critical. Would it be feasible to rent a build box for this, or would it simply be impractical? I'd be willing to donate towards this effort.

[peti]

@sfultong, test-building these packages is no issue. In fact, we do compile haskellPackages at http://hydra.nixos.org/jobset/nixpkgs/haskell-updates before merging changes. The issue is not knowing whether a package builds or not, the issue is doing something about those 6,417 packages that we know not to compile.
