Pip install RPIO, RPi.GPIO ... error

Installing and Using OpenWrt
#1

Hello friends sorry for my english. I have RpiZero WH and i build Openwrt 18.06 branch.
Everything works great. But I have a problem installing the RPi.GPIO, RPIO python package.

Every time I have the same error. Maybe someone would help me with this. I would be very grateful for help.

You "can't" compile or build Python packages (or anything else, for that matter) on your OpenWrt box. If pip needs to build a binary, then it needs to be done on a build host as a package.

I don't see RPIO available as a package. You might want to examine other options for GPIO manipulation.

(Also take note of the Python 2 EOL notice. OpenWrt will be following shortly, with only Python 3 packages accepted.)

Yes you can, use pip,

for example try:

pip install requests
pip install configparser
pip install logging

it works.

#4

try:

opkg install python-setuptools
pip install wheel
pip install venv

Sorry, my mistake, it was:

pip install virtualenv
and
opkg install python-dev

then upgrade pip form 9.0.3 to 19.1.1

pip install --upgrade pip

you should see something like this:

and finally gcc is needed to compile the two python packages:

opkg install gcc

(it takes a few minutes to install all dependencies)

I've just tested it (in a NOT Raspberry OpenWRT device with just 128 Meg of RAM) and both packages were successfully installed :wink:

Python can expand the capabilities of a router with OpenWRT adding many and many new features, just see my How-To's about LCD display and I2C sensors connected to an OpenWRT router :grinning:
