How to build Chart-cairo?

[rvl]

Chart-cairo is one of our dependencies.
It requires gtk2hs to build.

[angerman]

What exactly is the issue here? Does Chart-cairo list gtk2hs as a build-dependency?

There is the following custom-setup section in cairo.cabal

custom-setup
  setup-depends: base >= 4.6,
                 Cabal >= 1.24 && < 2.5,
                 gtk2hs-buildtools >= 0.13.2.0 && < 0.14

When installing cairo I get the following error:

building '/nix/store/8sg61zwbw9mq7x50ii7sqp7gld3i6acc-cairo-0.13.6.0-setup.drv'...

[MarcFontaine]

The nix-tools generate a setup-depends = [.... section that looks good,
however when I changed it to setup-depends = [ some-gibberish] it turned out that the setup-depends section is actually ignored.

Even with #124, I still can't get gtk2hs-buildtools to build:

Not sure what this means yet...

[angerman]

Could it be that

/nix/store/nk97zcz6ig8a5c6l43lkjl45f7avjf05-alex-3.2.4-exe-alex/share/x86_64-linux-ghc-8.6.4/alex-3.2.4-4z7ZKMgSjOO4NyQnKAtfMw-alex/AlexTemplate-ghc-nopred: openFile: does not exist (No such file or directory)

Is due to cabals mishandling of datadirs? haskell/cabal#5862

[ocharles]

No, applying the patch https://patch-diff.githubusercontent.com/raw/haskell/cabal/pull/6055.diff to Cabal does not fix this problem.

[ocharles]

I think this can now be closed as a duplicate of #31, but I think it's still a problem.
