Compiles solders, PyO3/maturin Python bindings for the Solana Rust SDK (transactions, keypairs, RPC types, and a LiteSVM test harness), into an abi3 wheel. Upstream publishes no riscv64 wheel.

Mirrors the linux-x86_64 job of upstream's build.yml.

Differs from upstream

  • Installs perl in-container before the build - openssl-sys's vendored OpenSSL build needs modules the image's minimal perl lacks.

Matrix: cp310-abi3 wheel reused across cp310-cp314; cp314t dropped - pyo3's abi3-py310 feature is unconditional in Cargo.toml, and an abi3 wheel cannot serve a free-threaded interpreter.

Testing

  • same as upstream

License: OK

Built on cp312 (aarch64, local, upstream's released wheel); 317 passed.
