Docker images for rust-embedded/cross, including clang12.
The images are based on rustembedded/cross images,
but adding clang12 and defining BINDGEN_EXTRA_CLANG_ARGS="--sysroot=... with cross-compilation toolchain path
(useful for crates using bindgen).
They are published as jenoch/rust-cross.
You can use them defining such Cross.toml file:
[target.x86_64-unknown-linux-musl]
image = "jenoch/rust-cross:x86_64-unknown-linux-musl"
[target.arm-unknown-linux-gnueabi]
image = "jenoch/rust-cross:arm-unknown-linux-gnueabi"
[target.arm-unknown-linux-gnueabihf]
image = "jenoch/rust-cross:arm-unknown-linux-gnueabihf"
[target.armv7-unknown-linux-gnueabihf]
image = "jenoch/rust-cross:armv7-unknown-linux-gnueabihf"
[target.aarch64-unknown-linux-gnu]
image = "jenoch/rust-cross:aarch64-unknown-linux-gnu"
