Install instructions?

[AphonicChaos]

I didn't see any install instructions, but have come up with (I think) a minimal stack.yaml configuration:

resolver: lts-7.19
compiler: ghcjs-0.2.1.9007019_ghc-8.0.1
compiler-check: match-exact

setup-info:
  ghcjs:
    source:
      ghcjs-0.2.1.9007019_ghc-8.0.1:
           url: http://ghcjs.tolysz.org/ghc-8.0-2017-02-05-lts-7.19-9007019.tar.gz
           sha1: d2cfc25f9cda32a25a87d9af68891b2186ee52f9

extra-package-dbs: []

With the above, I can compile a project (and apparently concur examples) with stack setup && stack build), assuming I've already added concur-core, concur-vdom, and ghcjs-vdomtobuild-depends`.

I'm currently building after having added the dependencies for ghcjs-ffiqq, so I'll update this if needed once that's done, or ask for help if I struggle. I'm not submitting a PR because I wasn't sure where/if you wanted this. Easiest thing I can think to do is add appropriate stack.yaml files to the examples directory of each backend directory and then briefly hint at them in concur's readme.

Thank for looking into this. This stack.yaml looks pretty good! Eventually I will upload concur to Hackage and Stackage so it'll be less complicated. Until then, this stack.yaml is a good start for people.

Keeping this issue open until install instructions are clearly specified in the docs.

Hi guys,

I tried installing concur with this starter template https://github.com/concurhaskell/concur-vdom-starter. However, I am getting the error below using the stack.yaml that comes with the template and also the suggested stack.yaml above. Would you be able to help me with the installation?

@Woody88 Looks like ghcjs-boot is failing on your system. Try this - https://stackoverflow.com/questions/48080510/stack-setup-error-solver-must-be-one-of-modular.
