在HarmonyOS鸿蒙Next的OpenHarmony平台中，调用Native so库时出现"myHypot of undefined"错误，通常是因为Native API绑定失败或so库未正确加载。请检查以下方面：确保so文件已正确打包到HAP中，native模块在build-profile.json5中正确定义，ArkTS侧与C++层的接口声明完全匹配，且so库针对当前设备架构编译。验证so文件完整性及加载路径是否正确。

从错误日志分析，问题出现在OpenHarmony 5.0.0平台无法正确加载Native SO库。具体表现为：

  1. 系统在/system/lib/module/目录下找不到libhello.z.so和libhello_napi.z.so文件
  2. 命名空间访问失败，错误代码errno=2（文件不存在）
  3. 最终导致myHypot属性读取失败，因为Native模块导出对象为undefined

这可能是由于：

  • OpenHarmony 5.0.0与HarmonyOS 6.0.0在Native库加载机制上存在差异
  • SO库未正确打包到HAP中或安装路径不匹配
  • 平台架构兼容性问题，建议检查SO库是否针对OpenHarmony平台正确编译

建议验证SO库在OpenHarmony 5.0.0设备上的存在性和可访问性，并确认编译目标平台设置正确。
