By default `buildPackage` will capture cargo's output and use it to determine which binaries should be installed (instead of just guessing based on what is present in cargo's target directory). If you are overriding the derivation with a custom build step, you have two options: 1. override `installPhaseCommand` with the appropriate installation steps 2. ensure that cargo's build log is captured in a file and point $cargoBuildLog at it At a minimum, the latter option can be achieved with running: cargoBuildLog=$(mktemp cargoBuildLogXXXX.json) cargo build --release --message-format json-render-diagnostics >"$cargoBuildLog" ''} false fi ''; nativeBuildInputs = (args.nativeBuildInputs or [ ]) ++ [ installFromCargoBuildLogHook jq removeReferencesTo removeReferencesToVendoredSourcesHook ]; })
