In your .cabal file, yes, but the cabal.project file can reference external packages. It has a slightly different syntax, though. I don't think it's supported with cabal-install 2.0.0.1. You may have to use HEAD instead of 2.4.0.0, I don't know. On 11/18/18 9:05 AM, Brandon Allbery wrote:

It doesn't. The source repo is for hackage documentation, not package retrieval.

If you can do this, this is news to me.

See: https://www.haskell.org/cabal/users-guide/developing-packages.html

From what I understand, you cannot use this to point to repos for dependencies, only to indicate the repo for the package you are defining.

You'd have to publish pack1 somewhere (on hackage or in your own hackage server), or use a different tool to declare the dependency. I don't know if cabal's new-build system addresses this at all.

Hello, I'm trying to reference an external source of a package within a sandbox, using cabal 2.0.0.1 http://2.0.0.1:

source-repository head    type: git    location: <git URL of pack1>

executable myExe     build-depends: base==4.10.1.0, pack1 -any

But "cabal -v install --only-dependencies" fails:

cabal: Encountered missing dependencies: pack1 -any

Any hint ?

Here's an example:

source-repository-package     type: git     location: https://github.com/well-typed/cborg     tag: 3d274c14ca3077c3a081ba7ad57c5182da65c8c1     subdir: cborg

I could not make it work with my version of cabal. So, I ended up with installing the package and referencing it in the sandbox with: cabal sandbox add-source <path-to-pack1> -- Fabien
