issues installing gong

[sp-daniel-pinyol]

Two issues 1) If I do "git clone ssh://github.com/nickng/gong.git" as in the README, I get "Permission denied (publickey)." with "git clone git@github.com:nickng/gong.git" it worked fine 2) Failure with "ghc Gong.hs"

thanks

$ cd gong; ghc Gong.hs

Could you try running cabal install to install gong? Full instructions are here: https://github.com/nickng/gong

thanks, but "cabal install" fails also. Maybe I have a too new haskell version? Or is it because I use a mac?

ghc --version

Cloning

Rather than

git clone ssh://github.com/nickng/gong.git

Try using the https:// URL for cloning as in the README

git clone https://github.com/nickng/gong.git

Dependencies

I don't think that a newer version of GHC is the cause here, judging by the fact that I use a more recent version of GHC (8.0.2) instead of the 7.10 versions in the README. As for whether mac versions makes a difference, I doubt that but I am afraid I don't have a machine in hand to test for that.

For what it's worth, my exact dependencies for the packages above are as follows:

cmdargs ==0.10.17
template-haskell ==2.11.1.0
unbound ==0.5.1
RepLib ==0.5.4

It looks like your template-haskell version (template-haskell-2.1...?) looks a bit off, so perhaps you can try installing these version of packages? Cabal is supposed to resolve the dependencies yet it is not doing its job well..

As a backup plan, you can try running a pre-built version of Gong via docker

$ alias Gong='docker run nickng/gong:popl17ae Gong'
