franka_interface build faild

[Ynao3]

I have some trouble installing frank-interface.My system is ubuntu20.04, and ros-noetic and real-time kernel have been successfully installed.I installed protobuf version 3.21.8 according to the installation document of franka-interface,but the following error occurred when build franka-interface:

I think it was the protoc version's reason and I changed it to 3.20.3, which caused the following problem:

Now I don't know how to solve this problem. I also tried to change GCC version, and G++version which were useless. What version did you use when you deployed it, how did you successfully deploy franka-interface, and how should I solve this problem? Thank you.

我在安装 frank-interface 时遇到了一些问题。我的系统是 ubuntu20.04，ros-noetic 和 real-time kernel 都安装成功了。我按照 franka-interface 的安装文档安装了 protobuf 3.21.8 版本，但是在构建 franka-interface 时出现如下错误：

我认为这是 protoc 版本的原因，我将其更改为 3.20.3，这导致了以下问题：

现在我不知道如何解决这个问题。我还尝试更改 GCC 版本和 G++ 版本，这些都是无用的。部署时使用了什么版本，franka-interface 是如何成功部署的，我应该如何解决这个问题？谢谢。

我也遇到了同样的问题，麻烦能指导一下吗
