g++: g++ (GCC) 13.3.0

# python3 -m pip install grpcio

Hi Satish,

This module will not install in AIX by using pip3 install grpcio

The reason being, there will be code changes you need to do specific to the header file and config files available in AIX and then try.

I would suggest you get the tarball from the PyPI website.
wget https://files.pythonhosted.org/packages/b6/e0/318c1ce3ae5a17894d5791e87aea147587c9e702f24122cc7a5c8bbaeeb1/grpcio-1.76.0.tar.gz

Then extract the tarball, cd to the source, and do it. pip3 install . -vv

For every error you get, you will need to fix it to compile and then try.
