Trouble running RPi.GPIO

General
1

I am trying to install RPi.GPIO for my Raspberry Pi 3 target build. I have installed Visual Studio 19 as described to enable py_gpio.o to be compiled. But it fails by saying it can’t find gcc. Do you know how to ensure it knows how to get to the gcc compiler in Visual Studio? Thank you

Hi,

Can you please share with us your Dockerfile so we can have a look?

HERE IS DOCKERFILE.TEMPLATE

FROM balenalib/%%BALENA_MACHINE_NAME%%-python:3-stretch-run

use install_packages if you need to install dependencies,

for instance if you need git, just uncomment the line below.

RUN install_packages git

Set our working directory

WORKDIR /usr/src/app

Copy requirements.txt first for better cache on later pushes

COPY requirements.txt requirements.txt

pip install python deps from requirements.txt on the resin.io build server

RUN pip install -r requirements.txt

This will copy all files in our root to the working directory in the container

COPY . ./

Enable udevd so that plugged dynamic hardware devices show up in our container.

ENV UDEV=1

main.py will run when container starts up on the device

CMD [“python”,"-u",“src/main.py”]

AND IN CASE THIS IS HELPFUL HERE IS REQUIREMENTS.TXT:
AWSIoTPythonSDK==1.0.0
wheel
gpiozero
RPi.GPIO

Hi,
the build worked for me using the Dockerfile.template below. Toolchain installation is in

RUN apt-get update -y && apt-get install build-essential

FROM balenalib/%%BALENA_MACHINE_NAME%%-python:3-stretch-run
# use install_packages if you need to install dependencies,
# for instance if you need git, just uncomment the line below.
RUN install_packages git
# Set our working directory

RUN apt-get update -y && apt-get install build-essential

WORKDIR /usr/src/app
# Copy requirements.txt first for better cache on later pushes

COPY requirements.txt requirements.txt
# pip install
# python deps from requirements.txt on the resin.io build server

RUN pip install -r requirements.txt
# This will copy all files in our root to the working directory in the container

COPY . ./
# Enable udevd so that plugged dynamic hardware devices show up in our container.

ENV UDEV=1
# main.py will run when container starts up on the device

CMD [“python”,"-u",“src/main.py”]

Hope this works for you …
