store-0.7.6 test suite fails to compile #153

Closed DanBurton closed 4 years ago

DanBurton commented 4 years ago

I think it's due to a newer smallcheck than expected.

/Users/dan/scratch/store-0.7.6/test/Data/StoreSpec.hs:96:3: error:
    Duplicate instance declarations:
      instance Monad m => Serial m CBool
        -- Defined at test/Data/StoreSpec.hs:96:3
      instance [safe] Monad m => Serial m CBool
        -- Defined in ‘Test.SmallCheck.Series’
   |
96 | $(do let ns = [ ''CWchar, ''CUShort, ''CULong, ''CULLong, ''CIntMax
   |   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^...

Etc for many similar errors.

I was able to reproduce this locally like so:

stack unpack store-0.7.6 && cd store-0.7.6
edit stack.yaml # add the following stack.yaml
stack build --test --bench --no-run-benchmarks --fast
# stack.yaml
resolver: nightly-2020-08-27

Thanks for reporting! Fixed in store-0.7.7 and removed from expected test failures in https://github.com/commercialhaskell/stackage/pull/5629
