can't build sample app with stack

[lippirk]

Describe the bug
when trying to build the 'quick start example', stack moans about lack of cabal

To Reproduce
Steps to reproduce the behavior:

step one - remove stack / cabal
$ cd ~ && mv .stack .stack.backup
$ which cabal // cabal not found
$ sudo pacman -Rsn stack // remove stack

at this point i have removed stack and made sure cabal is not on my PATH

step two - reinstall stack & do the 'quick start' command
$ sudo pacman -S stack
$ cd ~/github
$ git clone https://github.com/dmjio/miso && cd miso/sample-app && stack setup && stack build

actual behaviour

stuff^^

Copied executables to /home/mycomp/.stack/programs/x86_64-linux/ghcjs-0.2.0.9006020_ghc-7.10.3/bin:

• ghcjs
• ghcjs-boot
• ghcjs-pkg

• haddock-ghcjs
• hsc2hs-ghcjs

Expected behavior
build with no errors

Desktop (please complete the following information):

• OS: manjaro + xfce-4.12

Additional context

• It looks like stack setup doesn't install cabal...?
• i have not installed GHCJS (i am under the impression stack will do this for me ?)
• i have checked and cabal is indeed not in any of those directories
• if this is a stack issue i'm sorry, i am a haskell noob
• i don't understand the warning about /home/mycomp/.stack..... etc not being on the PATH variable -i don't want it on my PATH variable

many thanks for the help!

I guess you should try it with nix-build. The stack support for ghcjs is not very good lately.

The GHCJS codepaths are not currently being actively maintained in Stack

Most of the GHCJS community recommends Nix for setting up the toolchain

None of the regular Stack contributors are using the GHCJS support

Have you tried installing cabal globally and then running the command? The ghcjs boot process will look for cabal in your path. Ideally stack would install cabal first, and then provide a modified path for ghcjs, but I don't think it does this at the moment.

Stack support has been officially deprecated, we recommend using nix with miso's binary cache.
