Cannot generate the stack2nix.nix file (failure on packages from git repo)
Closed this issue · 7 comments
I try to generate the stack2nix.nix file of the stack2nix repository by using the stack2nix master built with Nix. But it fails on packages that come from git repositories. See the following log:

So, I wonder how you have generated the stack2nix.nix file!
The git and cabal versions of my system:
$ cabal --version
cabal-install version 2.2.0.0
compiled using version 2.2.0.1 of the Cabal library
$ git --version
git version 2.16.2
Huh, I don't get error: hash ‘e72fbdfe57941627633006fa1fb4003e26619424’ has wrong length for hash type ‘sha256’ locally. Can you write exact commands to run?
Could you try building #108
Should be merged to master now.
Sorry, i didn't have too much time today. I just built it and tried to run stack2nix but I got this error:
/nix/store/xhbmp2r5dvqm3haqrm0f4kn704mpp3zh-stack2nix-0.1.3.1/bin/stack2nix ./

I don't know if this is related to your PR...
You need to set NIX_PATH to recent 18.03 or master branch.
Ok, thanks.
I can now generate the stack2nix.nix file but I'm still not able to generate nix expressions from a stack.yaml that contains a package specified with the location keyword. I will provide more details in the next few days.
Do open an issue with steps to reproduce. I'm going to close this as duplicate of #102
