Missing xtensa-lx106-elf-g++

[wsw70]

I am trying to build a Dockerfile to better automatize the build of ESPurna binaries and I have a problem with xtensa-lx106-elf-g++.

The Dockerfile is simple: it downloads bash, curl, git and g++, and platformio ; then clones the repository and informs that when teh container is ran, pio run -e ... will be launched.

FROM python:2-alpine
RUN apk add --no-cache bash curl git g++
RUN python -c "$(curl -fsSL https://raw.githubusercontent.com/platformio/platformio/develop/scripts/get-platformio.py)"
RUN git clone https://github.com/xoseperez/espurna.git
WORKDIR /espurna/code
CMD pio run -e itead-sonoff-basic -e itead-sonoff-rfbridge -e itead-sonoff-touch -e aithinker-ai-light

The build is successful, but when running the container I get:

root@srv /e/d/espurna# docker run -e PLATFORMIO_BUILD_FLAGS="'-DUSE_CUSTOM_H'" -v /etc/docker/bin:/espurna/code/.pioenv -v /etc/docker/custom.h:/espurna/code/espurna/config/custom.h espurna

What is xtensa-lx106-elf-g++ and where should it come from?

[wsw70]

The python:2-alpineimage is too restricted. I changed to the default one (python:2) and it works great.

I will provide a complete description to add to the "contributed" section of the wiki once I can confirm everything works.

Just for completeness as I ran in to that same issue in #1754 . Alpine is missing libc which xtensa-lx106-elf-g++ is link against.
