# COPG — Termux build + package script
#
# Builds the Zygisk companion (.so) and the unified_controller for THIS device's
# ABI, assembles a flashable Magisk/KSU/APatch module ZIP, and drops it in
#   /storage/emulated/0/Download/COPG
#
# Termux only. Installs any missing prerequisites (clang, zip, llvm) itself.
# Multi-ABI release builds are done by the json.yml CI; this script builds the
# single native ABI for fast on-device build-&-test.
#
#   Usage:  ./build.sh [version] [versionCode]
#   e.g.    ./build.sh 4.3.5 435

# -static-libstdc++ is required for the TERMUX build only: Termux's clang links the
# .so against Termux's libc++_shared.so (a Termux-private path) which app processes
# can't resolve → Zygisk dlopen fails. The CI uses the NDK (c++_shared resolves on
# device) so it stays dynamic + smaller; this static build is just for local testing.
