Installing libary for Python 3

[Fritzi16]

There is this linked guide for installation: http://tmrh20.github.io/RF24/Python.html
I tried to follow it and change the commands for python 3. I am on a Raspberry Pi 3 with a fresh installation of Raspberry Pi OS (Raspbian).So I used the following commands:

1.)
sudo apt-get install python3-dev libboost-python-dev //no libboost-python3-dev available

sudo ln -s $(ls /usr/lib/arm-linux-gnueabihf/libboost_python-py3*.so | tail -1) /usr/lib/arm-linux-gnueabihf/libboost_python3.so //didnt work at all. Always said "Data is already existing

2.)
sudo apt-get install python3-setuptools //worked fine

3.)
./setup.py build OR python3 setup.py build //both brougt errors saying that there is no such data or directory. after some digging and trying something worked

4.)
sudo ./setup.py install OR python3 setup.py build //also the same, worked after trying for a long time and digging in places

In the end, I am able to run following code with Python 2 but not with Pyhton3.

import time import RPi.GPIO as GPIO from RF24 import *

So in the end it was not a successfull installation... Could it be, that something changed over the time with the OS and thats the reason for failing?

Please help. Already trying everything for days -.-

Best regards, Fritzi16

Here is what works for me on an older RPi3 that is pretty much up to date:

1. sudo apt-get install python3-dev libboost-python-dev
2. Issue#1, had to modify the line to:
   sudo ln -s $(ls /usr/lib/arm-linux-gnueabihf/libboost_python3-py3*.so | tail -1) /usr/lib/arm-linux-gnueabihf/libboost_python3.so
   got:
   ln: failed to create symbolic link '/usr/lib/arm-linux-gnueabihf/libboost_python3.so': File exists
   This is normal since I've run through this before
3. sudo apt-get install python3-setuptools
4. python3 setup.py build I'm guessing your issue here was not building & installing the library in c++ first? This needs to be clearly stated in the python section.
5. sudo python3 setup.py install
6. Running the example with python3 gave error about RPi.GPIO, so sudo apt-get install python3-dev python3-rpi.gpio
7. sudo python3 pingpair_dyn.py Up and running..

So the takeaways here are I think I need to update the sudo ln -s linking line and link to the c++ build instructions in the python wrapper info?

Thank you sooooooo MUCH!!!!!!

deleted everyting again, used following commands to get the libary:

mkdir ~/rf24libs
cd ~/rf24libs
git clone https://github.com/TMRh20/RF24
cd ~/rf24libs/RF24
./configure
sudo make install

And after that everything you wrote worked perfectly fine! But I had to add a cd pyRF24/ between your 3. and 4.

Thanks again! In the end I feel like a dumb idiot.

So to summ it up to a clear solution:

mkdir ~/rf24libs
cd ~/rf24libs
git clone https://github.com/TMRh20/RF24
cd ~/rf24libs/RF24
./configure
sudo make install
sudo apt-get install python3-dev libboost-python-dev
sudo ln -s $(ls /usr/lib/arm-linux-gnueabihf/libboost_python3-py3*.so | tail -1) /usr/lib/arm-linux-gnueabihf/libboost_python3.so
sudo apt-get install python3-setuptools
cd pyRF24/
python3 setup.py build
sudo python3 setup.py install
sudo apt-get install python3-dev python3-rpi.gpio

and the libary should be installed and work with Python 3
