# 一键交叉编译 Linux 采集端（amd64 + arm64），输出与 dist/install_mengyamonitor.sh 发布路径一致。
#
# 用法（在 mengyamonitor-backend-client 目录下）:
#   chmod +x build_linux.sh && ./build_linux.sh
#
# Windows: Git Bash 同上；或在项目目录执行:  powershell -ExecutionPolicy Bypass -File .\build_linux.ps1
#
# 可选环境变量:
#   BINARY_NAME   默认 mengyamonitor-agent
#   OUT_DIR       默认 dist（相对本脚本所在目录）
