Running in a docker container #1411

Closed Apollorion closed 2 years ago

I run a home kubernetes cluster and want to add the raspberry pi as a node to said cluster and run this project on that node. I am struggling to get the python libraries to install within a container. Any suggestions or help I could get with this? I was able to get it into install on my pi directly but its not going so swell in a container.

Currently this is what I have the container running:

FROM ubuntu:20.04

RUN apt-get update && apt-get install -y git make build-essential python3 python3-distutils \
    && git clone https://github.com/hzeller/rpi-rgb-led-matrix.git \
    && cd rpi-rgb-led-matrix \
    && make build-python PYTHON=$(which python3) \
    && make install-python PYTHON=$(which python3)

It keeps erroring here:

#5 33.28 x86_64-linux-gnu-gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O2 -Wall -g -fstack-protector-strong -Wformat -Werror=format-security -g -fwrapv -O2 -g -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -fPIC -I../../include -I/usr/include/python3.8 -c rgbmatrix/core.cpp -o build/temp.linux-x86_64-3.8/rgbmatrix/core.o -O3 -Wall

Probably missing python development files try installing python-dev with apt.

Wow EZPZ yup that was it, thank you so much!

I have recently taken up trying to get this to work in a docker container, and while it is working I have noticed very bad flicker relative to running the code without the docker container. Did you face this issue?

@stevenbrookslv Its been a really long time since I looked at this project. But I've been running my raspberrypi with this project in a docker container for a few years now without issue.

If you wanna dig through my source code, maybe something will stand out to you? This is my project here: https://github.com/Apollorion/led-project

Are you running the program in docker or only using docker to build the images? could it be a debug build vs optimization kind of thing? compiling a binary in the docker container shouldn't really be causing such issues.

maybe you are loading your cpu a lot somehow?
