Node-red with wiringpi and node-red-contrib-rcswitch2 - having trouble installing

Product support
1

I’ve started from https://github.com/resin-io-projects/resin-node-red to deploy a node-red via resin. Works great!

So I started adding some node-red plugins that I use and that’s working fine too! (kudos for that)

Then comes “node-dht-contrib-rcswitch2” https://flows.nodered.org/node/node-red-contrib-rcswitch2 which depends on the rcswitch-pi library https://github.com/r10r/rcswitch-pi . I see that there’s an alpine pkg for wiringpi. So I try to introduce the following :

RUN apk add --no-cache make gcc g++ python wiringpi && \
  JOBS=MAX npm install -g node-red-contrib-rcswitch2 --production --silent && \
  apk del make gcc g++ python wiringpi && \
  npm cache clean --force && rm -rf /tmp/*

This fails in the following way :

There doesn’t seem to be a wiringpi-dev in alpine. I’m not familiar with alpine, Is there some way of installing the development headers like one would do with a -dev package in debian ?
