What versions of criterion and optparse-applicative (a dependency of criterion) are you building?

My apologies,...1.5.9.0 criterion and optparse-applicative >=0.13 pointing to latest repo 0.16.1.0

--I removed ",Ann" from line 38 and line 214
--added import Text.PrettyPrint.ANSI.Leijen (pretty, Doc, text)
--added ansi-wl-pprint >= 0.6.9 cabal file build dependencies

and it completed the build process and installed using 8.10.4 ghc

Thanks. I'm a bit confused by this bug report, as I'm unable to reproduce the issue using the versions of criterion/optparse-applicative that you mentioned. What's more, this is line 38 of Criterion/Main/Options.hs in criterion-1.5.9.0:

criterion/Criterion/Main/Options.hs

Line 38 in 019a1b9

import Options.Applicative.Help.Pretty ((.$.))

This doesn't import Ann, which differs from what the error message in #243 (comment) shows. Are you sure you are using the original, unmodified version of criterion-1.5.9.0 from Hackage?

Thanks for your time and your assistance! The repo at https://github.com/input-output-hk/criterion.git indicates that its a fork of the Haskell/criterion repo, albeit a fork that is one commit ahead of the Haskell master. Somehow throughout this process and before I submitted this issue, I thought I saw that both IOHK and Haskells master had 'Ann' added to line 38 but I was mistaken! I apologize for the confusion on this!
