[1 of 6] Compiling Text.Regex.PCRE.Wrap ( dist/build/Text/Regex/PCRE/Wrap.hs, dist/build/Text/Regex/PCRE/Wrap.o )

Text/Regex/PCRE/Wrap.hsc:158:33: error:
    • Could not deduce (Control.Monad.Fail.MonadFail m)
        arising from a use of ‘makeRegexM’

Also biting regex-tdfa-text.

I made revisions for regex-tdfa-text. However, it looks like that users should migrate out of it.

• Trustees made an NMU 4 years ago: regex-tdfa-text doesn't build on GHC 7.10 #40
• regex-base-0.94 provides Extract Text instance.

regex-pcre-builtin reviewed

[hvr]

@phadej re those -text packages; I'm planning to add Text support to regex-pcre and regex-posix (see e.g. https://github.com/haskell-hvr/regex-pcre/commits/wip/text -- which I deferred to the next minor rls of regex-pcre due to some subtle bugs I couldn't get out in time)

[phadej]

I'm closing this. It has been quiet related to this general issue, so if there are some issues, they can be handled as regular ones.
