## Summary - `zig-arm64-linux` CMake preset was missing `AVM_TRANSPILER_LIB` - `avm-transpiler/bootstrap.sh` had no `arm64-linux` case in `build_cross` This adds `arm64-linux` cross-compilation to avm-transpiler (triggered on release via `semver check`) and wires up the `zig-arm64-linux` preset to the resulting library.

## Summary - The `bb-cpp-cross-arm64-linux` Makefile target depended on `avm-transpiler-native` instead of a cross-compiled arm64-linux avm-transpiler - This caused `ninja` to fail because `libavm_transpiler.a` was missing at the `aarch64-unknown-linux-gnu` target path - Adds the missing `avm-transpiler-cross-arm64-linux` target and fixes the dependency so the correct cross-compiled library is built before the barretenberg ARM64 Linux link step Follows up on #20814 which added avm-transpiler arm64-linux support to `bootstrap.sh` and `CMakePresets.json`, but the Makefile (introduced later) was never wired up.

Summary Makefile: The bb-cpp-cross-arm64-linux target depended on avm-transpiler-native instead of a cross-compiled arm64-linux avm-transpiler, so the cross-compiled libavm_transpiler.a was never built. Adds the missing avm-transpiler-cross-arm64-linux target and fixes the dependency. barretenberg-rs release: The release function would error out if generated Rust bindings (api.rs, generated_types.rs) weren't present, even though it's trivial to generate them. Now generates them on-the-fly instead of failing. Follows up on #20814 which added avm-transpiler arm64-linux support. Co-authored-by: ludamad <adam.domurad@gmail.com>

…20932) ## Summary Backports two fixes from `next` that enable the AVM transpiler for `linux/arm64` release builds, resolving [#20793](#20793) — `aztec compile` fails with "AVM Transpiler is not enabled" on `linux/arm64`. **Cherry-picked from:** - #20814 — added `arm64-linux` cross-compile to `avm-transpiler/bootstrap.sh` + wired `AVM_TRANSPILER_LIB` in `CMakePresets.json` - #20932 — fixed Makefile dependency (`bb-cpp-cross-arm64-linux` was depending on `avm-transpiler-native` instead of `avm-transpiler-cross-arm64-linux`), plus `barretenberg-rs` release fix **Root cause:** The `zig-arm64-linux` CMake preset was missing `AVM_TRANSPILER_LIB`, and `avm-transpiler/bootstrap.sh` had no `arm64-linux` case in `build_cross`. The arm64-linux bb binary was compiled without `ENABLE_AVM_TRANSPILER`. **Changes:** - `avm-transpiler/bootstrap.sh` — add `arm64-linux` case to `build_cross` - `barretenberg/cpp/CMakePresets.json` — wire `AVM_TRANSPILER_LIB` for `zig-arm64-linux` preset - `Makefile` — add `avm-transpiler-cross-arm64-linux` target, fix `bb-cpp-cross-arm64-linux` dependency - `barretenberg/rust/bootstrap.sh` — add `release` function with on-the-fly binding generation - `barretenberg/ts/scripts/copy_cross.sh` — relax arch check for release context **Conflict resolution:** `barretenberg/rust/bootstrap.sh` had a minor conflict — the `release` function didn't exist on v4. Resolved by accepting the full function. ## Test plan - [x] Native avm-transpiler build succeeds - [x] Makefile targets verified: `avm-transpiler-cross-arm64-linux`, `bb-cpp-cross-arm64-linux` dependency corrected - [x] CMake preset verified: `zig-arm64-linux` has `AVM_TRANSPILER_LIB` pointing to correct cross-compiled path - [ ] Full cross-compilation validated in release CI Closes #20793 ClaudeBox log: http://ci.aztec-labs.com/596d4a62f30fd2f0-2
