package/cargo: pass appropriate library path to the linker

2019-01-17T22:01:11+00:00

When linking the host cargo binary, the linker should be told to find libraries in $(HOST_DIR)/lib, otherwise it will not work libraries such as libhttp_parser. This was found with per-package directory support, where the build failed with: = note: /usr/bin/ld: cannot find -lhttp_parser collect2: error: ld returned 1 exit status In order to fix this, instead of passing -L$(HOST_DIR)/lib during the build of Cargo, we make sure all flags in $(HOST_LDFLAGS) are passed.

host-cargo: select host-rustc

2018-06-10T13:57:55+00:00

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 Signed-off-by: Thomas Petazzoni

cargo: use HOST_CARGO_DL_DIR instead of CARGO_DL_DIR

2018-04-02T18:50:50+00:00

The infrastructure only provides HOST_CARGO_DL_DIR, because this package is host only. Ideally the infra should provide CARGO_DL_DIR, but it doesn't currently, and that requires more significant changes. Signed-off-by: Maxime Hadjinlian Signed-off-by: Thomas Petazzoni

packages: use new $($PKG)_DL_DIR) variable

2018-04-02T13:53:53+00:00

Instead of DL_DIR, the package should now use $(PKG)_DL_DIR to ease the transition into a new directory structure for DL_DIR. This commit has been generated with the following scripts: for i in $(find . -iname "*.mk"); do if ! grep -q "\$(DL_DIR)" ${i}; then continue fi pkg_name="$(basename $(dirname ${i}))" [ "${pkg_name}" = "package" ] && continue raw_pkg_name=$(echo ${pkg_name} | tr [a-z] [A-Z] | tr '-' '_') pkg_dl_dir="${raw_pkg_name}_DL_DIR" sed -i "s/\$(DL_DIR)/\$($pkg_dl_dir)/" ${i} done Signed-off-by: Maxime Hadjinlian Signed-off-by: Peter Korsgaard

rustc: use RUSTC_{HOST,TARGET}_NAME

2018-02-13T22:09:47+00:00

utils/check-package complains as follows: package/rustc/rustc.mk:10: possible typo: RUST_TARGET_NAME -> *RUSTC* package/rustc/rustc.mk:18: possible typo: RUST_HOST_NAME -> *RUSTC* As RUST_{HOST,TARGET}_NAME are related to the Rust compiler, it sounds sensible to rename them to RUSTC_{HOST,TARGET}_NAME. So update all rust related packages to use the new variables. Signed-off-by: Eric Le Bihan Signed-off-by: Thomas Petazzoni

cargo: new package

2018-02-05T13:57:48+00:00

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.
