This repository contains a Docker build file that cross-compiles rust from a github source for Haiku.
The build can be configured with the following build arguments:
| Argument | Description |
|---|---|
| HAIKU_CROSS_COMPILER_TAG | The tag of the Haiku cross-compiler image. For example x86_64-r1beta4. |
| RUST_REV | The git tag/branch to build from, e.g. 1.69.0 or haiku-nightly. |
| RUST_REPO | The rust repository to check out. |
| HAIKUPORTS_URL | The base URL for the Haiku Ports package repository matching your compiler image. |
| INSTALL_PACKAGES | The packages that should be downloaded and installed from HaikuPorts for this build. |
| SOURCE_FIXUP_SCRIPT | A script that is run after the checkout is completed, usually to fix dependencies |
| RUST_XPY_COMMAND | The command passed to x.py, usually build or dist. |
| RUST_XPY_CONFIG | The config.toml for the build, for example configs/config-stable-x86.toml |
The example below builds the tag 1.73.0 for the x86 platform, based on an Haiku
r1beta4 cross compiler image. It uses a stable config.toml, and issues the dist command to
build the archive files that can be distributed onwards.
podman build --build-arg HAIKU_CROSS_COMPILER_TAG=x86_gcc2h-r1beta4 \
--build-arg RUST_REV=1.73.0 \
--build-arg RUST_REPO=https://github.com/rust-lang/rust \
--build-arg HAIKUPORTS_URL=https://eu.hpkg.haiku-os.org/haikuports/master/x86_gcc2/current/ \
--build-arg INSTALL_PACKAGES="openssl_x86 openssl_x86_devel nghttp2_x86 nghttp2_x86_devel" \
--build-arg SOURCE_FIXUP_SCRIPT=patches/fix-1.73.0.sh \
--build-arg RUST_XPY_COMMAND=dist \
--build-arg RUST_XPY_CONFIG=configs/config-stable-x86.toml \
--tag rust-haiku-x86_gcc2h:1.73.0 .All build artifacts are kept in /build/rust. If you pass the parameter dist to
RUST_XPY_COMMAND, then the packages can be found in /build/rust/build/dist.
If building rustc for Haiku is successful, then the image will be set up to allow you to use the
generated cross-compiler. You can use cargo's --target parameter to compile for the Haiku target
that matches the platform the image is built for.
For example:
cargo build --target x86_64-unknown-haiku
