I successfully installed a custom rust package (see "*Howto supply cargo-build-system dependency to guix package definition* <https://lists.gnu.org/archive/html/help-guix/2023-05/msg00009.html>").
It is located in /gnu/store/10sivvy746n5jdnsgny5afxpwa5yzy5f-rust-rustscan-2.1.1/bin/rustscan It's definition is (define-public rust-rustscan-2 (package (name "rust-rustscan") (version "2.1.1") ...)) But I'm getting a failure when trying to reference it in a local profile, using specifications->manifest A. How do I get more detail on the error, in order to troubleshoot. --debug isn't yielding anything B. How do I make rust-rustscan (my custom build of a rust package), available in a global profile. # guix/packages/manifest.scm (specifications->manifest '("rust-rustscan-2")) ;; Also fails... (specifications->manifest '("rust-rustscan")) # bash $ guix package -m guix/packages/manifest.scm guix package: error: rust-rustscan-2: unknown package guix package: error: failed to load 'guix/packages/manifest.scm': gnu/packages.scm:551:4: In procedure specification->package+output: $ guix package -m guix/packages/manifest.scm --debug=5 guix package: error: rust-rustscan: unknown package guix package: error: failed to load 'guix/packages/manifest.scm': gnu/packages.scm:551:4: In procedure specification->package+output: Throw to key `quit' with args `(1)'.
