Build opencode-termux

Make Targets

make all VER=1.18.27 PKG=both        # Build all families for a version
make batch VERS='1.18.15 1.18.27' PKG=deb  # Build range
make selfcheck                        # Validate setup

Family-specific targets

make family-glibc VER=1.18.27        # Glibc line only
make family-native VER=1.18.27       # Native line only
make family-compressed VER=1.18.27   # Compressed (UPX) only

Batch scripts

• scripts/range-build.sh — DRY=1 mode, disk guardrail, continue-on-fail
• scripts/fleet-upx.sh — Distributed UPX compression
• scripts/sha-stage.sh — SHA256SUMS accumulation
• scripts/push-stage.sh — Dry-run release upload

Transplant Pipeline (Native)

The native line uses a transplant-revive pipeline:

1. Extract: Base Bun ELF from official Android build
2. Detect: Section format (auto per Bun version)
3. Convert: Module graph insertion
4. Patch: BUN_COMPILED.size + offsets
5. Assemble: Final ELF layout
6. Revive: Runtime resurrection surgery
7. Verify: Self-test run

After transplant, a seccomp-harden step adds the SIGSYS crhandler shim.

Build Requirements

• Bun (for transplant pipeline)
• NDK (for bionic libopentui.so build)
• UPX (for compressed variant)
• make, bash, standard coreutils
