Failure to build Pandoc 2.0 on Mac OS X

Failure to build Pandoc 2.0 on Mac OS X

[Axel Kielhorn]

I would like to try Pandoc 2.0 (from git) but when building with


The Glorious Glasgow Haskell Compilation System, version 7.8.4


i get:

src/Text/Pandoc/Readers/TWiki.hs:495:3:

             <|> (return $ (B.str "\8220") B.<> contents) }

Do I need to upgrade my Haskell to 8.0.2?

[John MacFarlane]

It's a known issue, which I don't know exactly how to fix.
For now, we're not supporting ghc 7.8 for pandoc 2.

The cabal file says:

Tested-With:     GHC == 7.8.4, GHC == 7.10.2, GHC == 8.0.1

Well, I upgraded to 8.0.2 which was probably a mistake, because now I get:

cabal: Entering directory '.'
Configuring pandoc-2.0...
setup: failed to parse output of 'ghc-pkg dump'
cabal: Leaving directory ‚.'

Pandoc 1.9.2.1 from cabal build without problems.

Should I go back to 7.10.2 or 8.0.1?

AFAIK ghc 8 and greater is good... btw, if you have trouble with cabal I 
can highly recommend stack instead:

Well, stack installed ghc 8.0.1 and rebuild all the libraries.
Now I have an almost current pandoc.

But I can’t tell whether this is a cabal or a 8.0.2 problem.

Re: Failure to build Pandoc 2.0 on Mac OS X

[John MacFarlane]

I wonder if ghc 8.0.2 requires a more recent version of
Cabal than you have?  We test with ghc 8.0.2 and cabal 1.24.

I’m using
cabal-install version 1.24.0.2
compiled using version 1.24.2.0 of the Cabal library 

which came with ghc 8.0.2

    Versions available: 1.18.1.7, 1.20.0.3, 1.20.0.4, 1.22.6.0, 1.22.7.0,
                        1.22.8.0, 1.24.0.0, (1.24.1.0), 1.24.2.0 (and 41 others)
    Versions installed: 1.24.2.0

Looks good.
