cargo: new package This new package provides Cargo, the Rust official package manager. Cargo is written in Rust and uses Cargo as its build system. It also depends on other Rust packages. Normally, a previously installed version of Cargo would be used to: 1. Fetch the dependencies. 2. Build the new version of Cargo, using the available Rust compiler. But the fetching step prevents offline builds. So instead two features of Cargo are leveraged: vendoring [1] and local registry. First, a tarball of the build dependencies generated using `cargo vendor` is fetched along with Cargo source code. Then, the build process is as follows: 1. The tarball of the build dependencies is uncompressed in a local registry. 2. A snapshot of Cargo, provided by cargo-bin, builds the final version of Cargo. 3. A configuration file telling Cargo how to cross-compile programs for the target is generated and installed. Currently, only the host variant is provided.

host-cargo: select host-rustc Buildroot documentation specifies that cargo-based package should only depends on BR2_PACKAGE_HOST_RUSTC_ARCH_SUPPORTS and selects BR2_PACKAGE_HOST_CARGO but this fails with the following error: warning: (BR2_PACKAGE_LIBRSVG) selects BR2_PACKAGE_HOST_CARGO which has unmet direct dependencies (BR2_PACKAGE_HAS_HOST_RUSTC) Indeed, host-cargo depends on BR2_PACKAGE_HAS_HOST_RUSTC which is selected only when host-rustc is selected. So instead of having to select both cargo and rustc in each cargo-based package, replace BR2_PACKAGE_HAS_HOST_RUSTC dependency by BR2_PACKAGE_HOST_RUSTC_ARCH_SUPPORTS and select BR2_PACKAGE_HOST_RUSTC Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> 2018-06-10 15:38:56 +02:00			`depends on BR2_PACKAGE_HOST_RUSTC_ARCH_SUPPORTS`
