This PR is a counter part of mimblewimble/grin#3743 , which adds nix/flake support to the daemon. The following description is almost identical.
Motivation
This PR enables power users to easily and reliably build the project from source code.
Expectation
A user with the nix package manager installed can build the project with the following command:
nix build github:mimblewimble/grin-walletand expect the resulting binaries in
./result/bin/.Testing
If flake hasn't been enabled, use
nix build --extra-experimental-features 'nix-command flakes'in place ofnix build.A test run for this PR can be achieved using my forked repo with the following command:
nix build github:chives101/grin-wallet/flakeand expect a binary at./result/bin/grin-wallet.Or by entering the project folder and do
nix buildafter applying the PR.Maintenance
Each time
cargo.lockis updated,cargoLock.outputHashesneeds to beupdated in
flake.nix. It can be done by simply giving a dummy hash, and observe the errorgenerated from the build log.
Dev notes
This PR is the result of a simple adaptation of the code from this blog post:
