RPM packaging utilities building Rust bin crates.

This is a fork of the Fedora Rust SIG's rust2rpm.

This code is made available under the MIT license.


Ensure your main source has a Cargo.lock, or generate one by unpacking it and running cargo generate-lockfile and add it as an additional source.


Use the %cargo_bundle_crates macro to add source lines for crates from crates.io. Usage:

  • -l N: SourceN is the Cargo.lock.
  • -t N: SourceN is a tarball that contains the Cargo.lock.
  • -n DIRNAME (only with -t): The Cargo.lock is under the directory DIRNAME in the tarball. This defaults to %{name}-%{version}.


Source0:        https://github.com/BurntSushi/ripgrep/archive/%{version}/%{name}-%{version}.tar.gz
%cargo_bundle_crates -t 0

%cargo_prep, %cargo_build, %cargo_install, %cargo_test

Use these macros in your %prep, %build, %install, and %test sections, respectively.

%cargo_prep is to be run after %setup and unpacks sources under $PWD/.registry. If you have patches to dependency crates, you will need to apply them after %cargo_prep.

Do not add additional arguments to these macros, as it will not do what you expect. Provide additional arguments to cargo by defining %cargo_args:

%global cargo_args --features blah



In order to generate automatic bundled(crate(name)) = version provides, %cargo_install writes the output of cargo metadata --format-version 1 to %{_cargometadir/%{name}.json. You will need to list this in your %files section; we recommend marking it as %doc so users can opt out of installation with RPM's --nodocs flag.

Fedora's packaging doctrine requires that source code of packages in statically-compiled languages such as Go or Rust must be distributed as separate devel packages that serve only to be used in BuildRequires for packages that build binaries, such as Docker or ripgrep.

In practice, this depends on functionality added in RPM 4.14 (support for with, without, and unless rich dependency operators), as different binaries will depend on different versions of these libraries that might be maintained in parallel. Amazon Linux 2 will remain on RPM 4.11 and so we are unable to utilize this.

We also do not believe the presence of these devel packages is useful to Amazon Linux customers, and find the approach of using a separate source RPM for each upstream dependency to be more cumbersome than other options for carrying patches for dependencies across multiple packages.

Disadvantages to this approach

Patches to library crates have to be maintained in all bin crates. (The bin crates all have to be rebuilt in that case regardless, however.) This will most commonly be seen with sys crates (library crates for C library functions) that have incorrect logic for finding system libraries.
