Compile for Alpine linux

[adaliszk]

Hey,

I wanted to use box86 for a docker image to add Raspberry Pi support but unfortunately have not been able to compile the repo just yet. Is there anyone out there who already solved this issue?

Right now these are the steps I do:

# syntax=docker/dockerfile:1.3-labs
FROM --platform="linux/arm64" alpine:3.15 

RUN <<COMPILE_BOX86

apk --no-cache --repository=https://dl-cdn.alpinelinux.org/alpine/edge/main \
  add coreutils git make python3 cmake nasm gcc gcc-arm-none-eabi libc6-compat

apk --no-cache --repository=https://dl-cdn.alpinelinux.org/alpine/edge/community \
  add add libstdc++6

mdir -p /box86 /box86-src && cd /box86
git clone https://github.com/ptitSeb/box86.git /box86-src

cmake /box86-src -DRPI4ARM64=1 -DCMAKE_BUILD_TYPE=RelWithDebInfo
make -j$(nproc)
make install

COMPILE_BOX86

The output:
