Unable to locate absl/log/absl_check.h while compiling using g++ a protoc-generated C++ file.

[Aditya Gurajada]

HI, folks --

• Platform: Linux Ubuntu 22.04.2 LTS
• g++ : g++ (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0
• protoc: libprotoc 23.4
• protocol buffers: v23.4

I am very stuck in trying to use protoc to generate Python bindings using --python_out argument. I have also installed protobuf-v23.4/ headers in my /usr/include/google dir.

Am experimenting with this version and have to next try how the --pyi_out feature works.

The problem I have now is that the generated C++ pb.cc file is not compiling. The error is as shown below [1].

I have installed the libabsl-dev package, but am not finding the log/ sub-dir under /usr/include/absl .

Checking around there was some post that suggested to add these flags to the cc, but that did not help either: -D ABSL_BUILD_TESTING=ON -D ABSL_BUILD_TEST_HELPERS=ON -D ABSL_USE_EXTERNAL_GOOGLETEST=ON

Github protocol buffer issue no.12201 talks about some incompatibility with s/w components involving protobuf / absl etc.

My questions are:

1. What may be the solution for this specific compilation issue I'm facing?
   
2. What is the stable version of protoc / protocol buffers one can use to not run into this missing-header-file (absl) issue?
3. Where are the how-to instructions to download a specific working version of protocol buffer? (I had to unzip the package and manually sudo cp'over the files to /usr/include ...)
4. Is this feature support of generating python bindings using protoc --python_out --pyi_out stable? (I've gone through the tutorials.)
   

Thanks, in advance,
