Mac M2设备使用Photon Fusion时libnanosocket兼容性问题求助

问题描述 #

• Windows平台上游戏的多人匹配与大厅系统运行正常，但在M2芯片Mac设备上创建/加入匹配时触发libnanosocket相关错误。
• Unity检视器中显示libnanosocket资源适配Intel CPU，修改设置并应用后会自动恢复为Intel架构，无法保存更改。
• 尝试直接修改二进制文件但无操作经验，且担忧修改后设置仍会复原。
• 重置DLL后出现新错误：EntryPointNotFoundException: nanosockets_address_set_ip。

解决方法 #

1. 升级Photon Fusion到兼容Apple Silicon的版本 #

旧版本Fusion可能未适配ARM64架构，前往Package Manager更新至最新稳定版，确保包含M系列芯片的支持。

2. 手动替换ARM64版本的libnanosocket库 #

• 定位Fusion插件目录下的MacOS库文件：Fusion/Plugins/MacOS/libnanosocket.dylib
• 确认是否存在ARM64架构的版本，若没有，从官方渠道获取或自行编译适配ARM64的库
• 替换后在Unity检视器中设置该库的CPU架构为ARM64，并勾选"Override"锁定设置，防止被自动覆盖

3. 调整Unity Player构建设置 #

• 打开Player Settings > MacOS > Architecture，选择Universal（同时支持Intel和ARM64）
• 关闭"Auto Graphics API"，手动添加Metal作为唯一渲染API，避免架构冲突

4. 清理缓存并重新导入Fusion #

• 删除项目根目录下的Library文件夹，清空Unity缓存
• 重新导入Photon Fusion包，确保所有平台插件资源正确加载

5. 验证库符号导出 #

若出现EntryPointNotFoundException，使用终端命令检查库的符号是否存在：

nm -gU /path/to/libnanosocket.dylib | grep nanosockets_address_set_ip

如果未找到对应符号，需重新编译带有正确符号导出的ARM64版本库。
