Thank you for your hard work.

I tried build and test as following command, but I couldn't reproduce the error.

$ stack unpack ghci-hexcalc-0.1.1.0
$ cd ghci-hexcalc-0.1.1.0
$ rm -f stack.yaml && stack init --resolver nightly
$ stack build --resolver nightly --haddock --test --bench --no-run-benchmarks

Could you advise me how to reproduce the error?

[cdornan]

It is the test suite that is failing to build — could you try stack test?

[takenobu-hs]

Thank you for taking your time.

I also tried stack test, but it passed as following:

$ stack test

Warning: Failed to decode module interface:

ghci-hexcalc> Test suite test-ghci-hexcalc passed

I'm using Ubuntu 18.04LTS. My stack version is 2.3.1.
Is there another way to reproduce it?

[cdornan]

Hmn, @DanBurton, unless you have an idea as to what has happened, maybe we should enable tests again in case the problem has fixed itself.

[DanBurton]

I cannot reproduce this locally; it looks like it is an issue specific to the setup on Stackage's build server. I'm not sure why the binary package would be hidden but I'll look into it.

Thank you for dealing this!
