#!/usr/bin/env bash
# ============================================================================
#  VIZ Linux Build Script
#
#  Prerequisites:
#    - Install build dependencies first (once, as root):
#        sudo ./install-deps-linux.sh
#    - Ubuntu 20.04+ (24.04 Noble recommended for system Boost 1.74)
#    - CMake 3.16+
#    - GCC 8+ or Clang 3.3+
#    - Boost 1.71+
#    - Git
#
#  Usage:
#    ./build-linux.sh [options]
#
#  Options:
#    -t, --type TYPE         Build type: Release or Debug (default: Release)
#    -l, --lowmem            Build low memory node (LOW_MEMORY_NODE=ON)
#    -n, --testnet           Build for testnet (BUILD_TESTNET=ON)
#    -m, --mongo             Enable MongoDB plugin (ENABLE_MONGO_PLUGIN=ON)
#    -s, --static            Build shared libraries OFF (static linking)
#    --no-lock-check         Disable chainbase lock checking
#    --clean                 Remove and recreate the build directory before build
#    --install               Run make install after build
#    -j, --jobs N            Number of parallel jobs (default: nproc)
#    --boost-root PATH       Custom Boost installation path
#    --openssl-root PATH     Custom OpenSSL installation path
#    -h, --help              Show this help message
