I can't use protobuf on arch linux

Question

I'm learning to use protobuf, so I tried the official example from v23.4.

At the first time, I'm using the system package manager pacman to install protobuf, here's my version:

 sudo pacman -Q protobuf
protobuf 23.4-1
 sudo pacman -Q abseil-cpp
abseil-cpp 20230125.3-1

but when i make cpp, I got lots of errors, I intercept a part of it, is it long enough to show the problem?

After that, I have tried to follow the official install guide to install like this:

bazel build :protoc :protobuf
cp bazel-bin/protoc /usr/local/bin

I don't know if the bazel have install the runtime? Is it an automatical procession? When I do these things, I got same erros above.

Then, I tried to use bazel.

bazel build :add_person_cpp

Everthing works well, and the binary add_person_cpp and list_people_cpp works as well, I have tried to copy them to another machine, and they work, are they need the runtime? Or the runtime is just used for compile.

It's my first question here, if i haved made any mistake, plese inform me, thanks a lot for your answers.

Looks like either your compiler doesn't support string_view or you're compiling with an earlier standard that excludes it. What compiler and version are you using? — Retired Ninja, Jul 19 '23 at 04:51
@RetiredNinja thanks, here's the version: `g++ (GCC) 13.1.1 20230429`. the error is not only about string_view it's 18869 lines long. — Limpol R, Jul 19 '23 at 04:59
Generally it would be best to start with the first error and the compile command that generated it. — Retired Ninja, Jul 19 '23 at 05:12

Well, After I change the c++ standart in makefile to c++17, it seems work well. And the official cmake do works, now I'm trying to write my own cmake file.

add_person_cpp: add_person.cc protoc_middleman
    pkg-config --cflags protobuf  # fails if protobuf is not installed
    c++ -std=c++17 add_person.cc addressbook.pb.cc -o add_person_cpp `pkg-config --cflags --libs protobuf`

list_people_cpp: list_people.cc protoc_middleman
    pkg-config --cflags protobuf  # fails if protobuf is not installed
    c++ -std=c++17 list_people.cc addressbook.pb.cc -o list_people_cpp `pkg-config --cflags --libs protobuf`

I can't use protobuf on arch linux
