scripts

Scripts to cross compile "standard" Rust crates, like std and core, for the mips-unknown-linux-gnu target.

For reproducibility, these scripts target Debian Wheezy.

Here's an overview of what the scripts do:

  • Download the OpenWRT SDK. There are several SDKs, one per device "family" supported by OpenWRT. This script defaults to the Barrier Breaker release for the ar71xx/generic target, but this can be overridden with the SDK_URL variable.

  • Fetch the Rust source, and patch it to not pass a compile flag that's not recognized by gcc.

  • configure the Rust build system to target the mips-unknown-linux-gnu triple.

  • make && make install

  • Package only the cross compiled crates, which are found in the lib/rustlib/mips-unknown-linux-gnu folder.
