Fix cross-compilation error: use native ARM64 runner for Linux builds#269
Conversation
- Change from ubuntu-latest to ubuntu-24.04-arm for aarch64-linux builds - Resolves cross-compilation 'Exec format error' with backtrace-ext dependency - Uses GitHub's native ARM64 runners (GA since August 2025) - Each target now builds on its native architecture for optimal performance

Summary
ubuntu-24.04-armfor aarch64-linux buildsProblem
GitHub Actions was failing with cross-compilation errors when building aarch64-linux targets:
The issue was that we were using
ubuntu-latest(x86_64) runners to build aarch64-linux targets via cross-compilation, which fails with certain dependencies like backtrace-ext.Solution
Changed the workflow to use native ARM64 runners for each target:
ubuntu-latest→ x86_64-linux (native)macos-14→ aarch64-darwin (native)ubuntu-24.04-arm→ aarch64-linux (native) ← FixedTest Plan
Additional Context
This uses GitHub's latest ARM64 Linux runners which became GA in August 2025 and are free for public repositories.
