老路由华硕RT-N16(mpisle)使用版本v0.48.0以下一切正常，因为想使用0.49.0以上的xtcp新功能发现运行不了，请教有解决办法吗？因路由在外地，换路由暂时也不实际。谢谢大家。

大概率是新版本中 Go 不支持了，你可以考虑使用 Go1.18 去编译旧版本的源码试试看，也不一定能行了。

好的，谢谢，我试试，请问0.49是用哪个Go版本了。

[fatedier]

1.20

[jmlcx]

还是失败了，提示需要Go 1.19，但用1.19编译成功出来，又是上面的错误。

那就别折腾了吧，Go 会逐渐放弃对旧系统的支持，旧系统的兼容会增加很大的维护负担和成本，所以也可以理解。

frp 始终会用最新的 Go 版本（或者兼容最近两个版本）来编译，所以同样随着版本的更新也会逐渐不再支持旧的系统。

如果你自己有能力修改的话，也可以尝试移除掉你不需要的代码，仍然使用旧版本的 Go 编译，但是并不推荐，耗费精力，收益也不高。
