[grpc-io] Re: Consuming gRPC Server Reflection from C++ Client (that happens to also offer a Server Reflection)

[WD J]

I face the same problem, and the scenoria is Binary A use the 
grpc++_reflection.a and libB.so first not link the grpc++_reflection.a, 
build the binaryA, and libB.so recompile with linking the 
grpc++_reflection.a, then binaryA fatal with the same error information.

[grpc-io] Re: ImportError: /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.33' not found

[Anton Toernblom]

I was having the issue inside a docker container running on a Raspberry pi 
4 32bit OS.

It worked if i ran it with -it bash then did your instructions. Fails with 
a massive  error log  when added this to the 
dockerfile however,


FROM python:3.11
WORKDIR /usr/src/app
COPY main.py .

RUN apt-get update

RUN export PATH="$HOME/.local/bin:$PATH" && \
pip uninstall grpcio && \
pip uninstall grpcio-status && \
pip install grpcio==1.44.0 --no-binary=grpcio && \
pip install grpcio-tools==1.44.0 --no-binary=grpcio-tools

 This is the first time trying to use google pub/sub python package.

 Command that I used to install:
 python3 -m pip --no-cache-dir install grpcio

 I tried many other ways, all yield the same result. "sudo pip3..", 
 "sudo pip...", "pip3 ...", "pip..."
 It works perfectly on Ubuntu 20.04.
