install / make in docker?

[Simon Parten]

My ultimate goal is to draw some stuff on an e-ink screen. Sort of following instruction here at the moment.

 I had the hope, to be able to use Docker to simulate the Raspberry pi OS, and ease some of the dev pain points I happen to have. The first lines of the Dockerfile, are this.

FROM balenalib/raspberrypi4-64-debian-openjdk as build-env

RUN install_packages wget ca-certificates unzip git clang libssl-dev cmake build-essential libcap2 libcap-dev libc6-dev

RUN wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.71.tar.gz

RUN mkdir bcm2835

RUN tar zxf bcm2835-1.71.tar.gz

WORKDIR /bcm2835-1.71

RUN ./configure && make

RUN make check

The last line 'make check'. fails with this message.

I would openly acknowledge that I'm not particularly skilful in this arena, I guess my first question is whether this would be expected to work? 

With the followup question being if there's anything very obviously wrong with the commands I've put out?

I broke open the log file, and believe the interesting line to be this. 

#14 0.269 bcm2835_init: Unable to open /dev/mem: No such file or directory

I can see instruction on the homepage about this, but if I'm 100% honest, I don't understand them   well enough to construct the proper solution. :-(. I have the c libs that apparently are needed to work with / around this - libcap-dev libc6-dev

I suspect, this thread may offer a hint on why this doesn't work. 

https://forums.docker.com/t/dev-mem-no-such-file-or-directory-in-ubuntu-linux-14-04-container/28403/4

And speculatively added dmidecode  but got the same.

So my best guess, is that Docker doesn't provide some low level infrastructure, that this library assumes (probably quite reasonably) exists?

Hello

You will need to read the bcm2835 library documentation about user privileges
