When trying to select the hardware layer for the PiXtendV2, you will encounter the error "Compilation finished with errors!". This issue has been mentioned in the community forum. Looking at this codebase, this is also likely a problem for Fischertechnik, PiXtend, (PiXtend 2l), PiXtend 2s, Raspberry Pi (old), and the UniPi.
Steps to reproduce
Try selecting one of the mentioned hardware layers.
Temporary fix
It is possible to replace lpigpio with lwiringPi within ./webserver/scripts/compile_program.sh.
For anyone interested, my Dockerfile for the PiXtend V2 L will install and patch the compilation to get all things working:
FROM ubuntu:latest
ARG TZ
ENV TZ=$TZ
# Configure timezone
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
WORKDIR /app
# Install Raspberry Pi/PiXtend hardware support with dependencies
RUN apt update && \
apt install -y git sudo make build-essential
RUN git clone https://github.com/WiringPi/WiringPi.git && \
cd WiringPi && \
./build && \
cd .. && \
rm -rf WiringPi
# Install OpenPLC Runtime
# https://autonomylogic.com/docs/installing-openplc-runtime-on-linux-systems/
RUN apt-get update && \
apt-get install -y unzip python3 cmake wget
RUN git clone https://github.com/thiagoralves/OpenPLC_v3.git . && \
./install.sh rpi
# Copy initial configuration
COPY ./pixtend /app/webserver/
# Set PiXtend V2 L as default hardware
RUN cd ./webserver/core && \
../scripts/change_hardware_layer.sh pixtend_2l && \
cd ../..
# Fix build script for PiXtend

RUN sed -i 's/lpigpio/lwiringPi/g' ./webserver/scripts/compile_program.sh
# Compile default program
RUN cd ./webserver/scripts && \
./compile_program.sh blank_program.st && \
cd ../..
This is also my simplified docker-compose.yml that should be able to run this image:
