Can't get it working - RPi2, Python3, Stretch #419

Closed GordonTraveler closed 6 years ago

GordonTraveler commented 6 years ago

Hi.

I have an NRF24L01+ connected to my RPi2. It was working before like charm. But then I wanted to change to RPi3 and also from Python2 to Python3 and also made some updates as well and now I can't get it back running again.

What I have now: Raspberry Pi 2 Raspbian Stretch Lite (Kernel 4.9.59) Python 3

I tried a lot of libraries the last days. Nothing. Always the same result: Not working. Most of the tutorials and libraries are just outdated.

Right now I try to install it with this instructions: https://github.com/haseebehsan/RF24Python (Seems like they are all based on your library. Thats why I ask here)

$ sudo wget http://tmrh20.github.io/RF24Installer/RPi/install.sh
$ sudo chmod +x install.sh 
$ sudo ./install.sh

Installing fine. No Problems.

$ sudo git clone https://github.com/haseebehsan/RF24Python
$ cd ./RF24Python/pyRF24/pyRF24
$ sudo python setup.py install

Not fine. "FileNotFoundError: [Errno 2] No such file or directory: '../Makefile.inc'" There is a Makefile 2 directories below. But if I change the line in the setup.py then the error is 

Traceback (most recent call last):
  File "setup.py", line 39, in <module>
    process_configparams()
  File "setup.py", line 19, in process_configparams
    identifier, value = line.split('=', 1)
ValueError: not enough values to unpack (expected 2, got 1)

So I skip this step. (Skipping install steps is probably never good...)

$ cd ../pyRF24Network
$ sudo python3 setup.py install

Ends up in an error:

(If I compile it with python 2, then it is working. With Python3 not)

Last, but not least:

$ cd ../pyRF24Mesh
$ sudo python3 setup.py install

Result is the same as above. With Python2 is it working, with Python3 not.

I am really at the end of my nerves (and running out of time). Can someone help me to get it back running please. In general and especially with Python3. I am not a big Linux or Hardware expert. Please tell me what I can do to check something or to provide you with more information. Or maybe there is a working tutorial with Python3.

First off https://github.com/haseebehsan/RF24Python is a different repository. Secondly, you don't need sudo to clone a git repository.

Anyway, if you have already cloned the previously mentioned repo, you need to cd into it

cd RF24Python

# Build it.
./configure && make

# Build the Python modules.
cd pyRF24
python setup.py build

image No errors

Clarification

The error you're encountering about '../Makefile.inc' is because you're missing a build. Also, you need libboost installed.

GordonTraveler commented 6 years ago

As I said. With Python2 is no problem to build/install it. But try with Python3.

I know it is a different repository. But the basis is this one, isn't it? But maybe here is a Python wrapper too? I think I saw one somewhere. I saw so many pages and repositories the last hours/days... I lost overview. Sorry.

Maybe the best would be to start from scratch with this repo, if there is a Python3 wrapper/support. Can you tell me how to install it? And then step by step. I also red somewhere that there is a problem with the Kernel 4.* and SPI. Is that fixed already?

You need to link the following library, but worked like a charm:

~/RF24Python/pyRF24 $ sudo ln -s /usr/lib/arm-linux-gnueabihf/libboost_python-py35.so /usr/lib/arm-linux-gnueabihf/libboost_python3.so

You can also do an rpi-update and apt dist-upgrade.

Do you have libboost-dev installed?

GordonTraveler commented 6 years ago

Seems like yes. I found this script: https://github.com/G-Node/nixpy/blob/master/scripts/findboost.py I tried it with "python" and "python3". Both was fine.

I just tried to install the Python wrapper from this repository. I used "git clone https://github.com/nRF24/RF24" to clone the repo. Then "cd ~/RF24/pyRF24". And from here: http://tmrh20.github.io/RF24/Python.html... Step 1 and 2 was done before already. Step 3 "http://tmrh20.github.io/RF24/Python.html":

pi@RPI2:~/RF24/pyRF24 $ ./setup.py build
Traceback (most recent call last):
  File "./setup.py", line 39, in <module>
    process_configparams()
  File "./setup.py", line 14, in process_configparams
    with open('../Makefile.inc') as f:
IOError: [Errno 2] No such file or directory: '../Makefile.inc'

In "/RF24" is a "Makefile", but without ".inc". Shall I use this one? But I guess it is for something else, isn't it?

ghost commented 6 years ago

Did you do ./configure && make in the ./RF24 folder?

Edit

Why do you not want to use python 2?

GordonTraveler commented 6 years ago

No. I didn't (as I said... I am a beginner with this... sorry). Now I did and the ./configure && make went good... seems like.

make

After that I could do ./setup.py build. That was fine too. But I need it in Python3. So I did Python3 setup.py build. And this failed again (/usr/bin/ld: cannot find -lboost_python3).

setup

It can not find the lboost_python3. But why? Btw... I don't have a path "/usr/bin/ld".

ghost commented 6 years ago

ld is your linker, so if build-essential is installed, then that is installed as well. You can do: which ld to find its path.

As for your issue: It seems like python can't find the shared library for libboost. Could you do the following and attach the output?

ls /usr/lib/arm-linux-gnueabihf/libboost_python*

Or

find /usr -name "libboost_python*"

Hi conmarap. Thank you for your help.

Here is the output of this 3 commands: find

ghost commented 6 years ago

No problem. Ok awesome! In the output from ls the red line means that the symbolic link you performed last time didn't work so it's a broken link. Try removing that file (the link) and redo that. Then make sure it's cyan like the one below it. That should work.

GordonTraveler commented 6 years ago

Hi conmarap.

It was the broken link. Damn... such a simple thing. Took me several days of headache. I removed the old link, set a new one and the compiling errors disappeared. Took me now still an 2 hours to figure out that it works a bit different now. But finally it is running again. Can't tell you how happy I am. Now I can concentrade on more important things again :-) Thank you very much for your help and patience.

No problem mate. Good luck on your projects.
