我不知道如何解决它。有什么我错过的吗？
我希望它的构建不会出现错误。谢谢。
我在 Ubuntu 18.04 中遇到了同样的问题，但是 grpc 存档有很多发行版本（gitbranch --all），所以我决定为我的编译器找到最新版本（gcc --version 对我来说有 7.5.0），我做了以下步骤：
git clone https://github.com/grpc/grpc.git
cd grpc
git checkout v1.54.x
git submodule update --init
bazel build :all
对于 protobuf，您可以单独检查它，因为我认为 grpc 仅使用来自 protobuf 的有效负载。现在我使用 protobuf 26.0 版本，在 Ubuntu 18.04 中完美运行。
