Clone the Git repository in the normal way, check out the Git commit you want to base the Guix package on, and then do this: $ guix hash --recursive --exclude-vcs path/to/git-repo This is explained in the manual, section Invoking guix hash: https://www.gnu.org/software/guix/manual/html_node/Invoking-guix-hash.html
