Can not build with stack

[jdevoto]

Hello.

I have a small project. I tried to build it with stack and I get the following error

[15 of 28] Compiling Diagrams.TwoD.Path.Follow ( src/Diagrams/TwoD/Path/Follow.hs, .stack-work/dist/x86_64-linux/Cabal-2.0.1.0/build/Diagrams/TwoD/Path/Follow.o )

    /tmp/stack30251/diagrams-contrib-1.4.3/src/Diagrams/TwoD/Path/Follow.hs:64:21: error:
        • No instance for (Semigroup (Semi (Trail' Line V2 n) (Angle n)))
            arising from the 'deriving' clause of a data type declaration
          Possible fix:
            use a standalone 'deriving instance' declaration,
              so you can specify the instance context yourself
        • When deriving the instance for (Semigroup (Following n))

# Resolver to choose a 'specific' stackage snapshot or a compiler version.
# A snapshot resolver dictates the compiler version and the set of packages
# to be used for project dependencies. For example:
#
# resolver: lts-3.5
# resolver: nightly-2015-09-21
# resolver: ghc-7.10.2
# resolver: ghcjs-0.1.0_ghc-7.10.2

#  name: custom-snapshot

# resolver: lts-11.12
resolver: lts-10.10  # changed from the up

What happens if you change to diagrams-lib-1.4.2.3 in your extra-deps?

[jdevoto]

I get this message:

/tmp/stack4346/diagrams-contrib-1.4.3/src/Diagrams/TwoD/Path/Follow.hs:64:21: error: • No instance for (Semigroup (Semi (Trail' Line V2 n) (Angle n))) arising from the 'deriving' clause of a data type declaration Possible fix: use a standalone 'deriving instance' declaration, so you can specify the instance context yourself • When deriving the instance for (Semigroup (Following n)) | 64 | deriving (Monoid, Semigroup)

I have the same problem. There is no porblem if I use resolver: lts-11.12 in stack.yaml. But if I do this, then I get

/home/jdevoto/Haskell/Projects/heathsim/src/Lib.hs:9:1: error: Could not find module ‘Diagrams.Prelude’ Use -v to see a list of the files searched for. | 9 | import Diagrams.Prelude | ^^^^^^^^^^^^^^^^^^^^^^^

/home/jdevoto/Haskell/Projects/heathsim/src/Lib.hs:10:1: error: Could not find module ‘Diagrams.Backend.Cairo.CmdLine’ Use -v to see a list of the files searched for. | 10 | import Diagrams.Backend.Cairo.CmdLine | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Completed 5 action(s).

Thanks in advance for any help

@jdevoto Sorry for the delay in responding. What packages do you have listed in the build-depends field in your .cabal file? You need to list diagrams-lib and diagrams-cairo if you want to use those modules.

[jdevoto]

I did what you suggested putting diagrams-lib and diagrams-cairo in the package.yaml and it worked.

Thanks for your help!!!
