# Cross-compiles better-sqlite3 for the embedded Node 18.20.4 (nodejs-mobile) ABI
|
|
# for all three Android ABIs and writes the resulting better_sqlite3.node binaries
|
|
# into nodejs-assets/nodejs-project/prebuilds/<abi>/. main.js installs the one
|
|
# matching the device's actual process.arch at runtime — see
|
|
# installBetterSqlite3Prebuild().
|
|
#
|
|
# Unlike the old Node-12 build, NO binder.cpp patch is needed: Node 18's V8 10.2
|
|
# still exposes the (deprecated) v8::Object::CreationContext() that better-sqlite3
|
|
# 12.x uses, so it compiles as-is (deprecation warning only).
|
|
#
|
|
# Requires: Android NDK (ANDROID_HOME or ANDROID_NDK_HOME set), the Node 18 runtime
|
|
# staged into the plugin (scripts/install-node18-runtime.sh), and `npm install`
|
|
# already run in nodejs-assets/nodejs-project.
|
|
#
|
|
# Usage: ./scripts/build-better-sqlite3-node18.sh [abi ...] (default: all three)
