Third party Harmonix wrapped interface simulation compatibility for HarmonyOS PC system that enables devs to run linux elf binary with alpine rootfs support

Run linux elf binary (alpine rootfs also supported) on HarmonyOS PC, inspired by Termony, based on harmony-qemu.

Harmonix

Run linux elf binary (alpine rootfs also supported) on HarmonyOS PC, inspired by Termony, based on harmony-qemu.

Originally for quick verification to integrate qemu-user to Termony.

Working in progress, in the early stages.

Build

To build and install to your device, see Build Termony on Linux

Usage

• Build and sign hap of Harmonix

  • or download unsigned hap from Release page and sign by your self

• Install Harmonix to your HarmonyOS PC

• Download alpine minimal root filesystem from https://alpinelinux.org/downloads/ (aarch64 or x64)

• In HiShell, extract rootfs tar.gz file to data directory, for example /data/storage/el2/base/files/alpine

• Run qemu-harmonix-aarch64 to load busybox shell with rootfs and environment variables

cd /data/storage/el2/base/files/alpine
qemu-harmonix-aarch64 -E PATH=/bin:/usr/bin:/sbin -E HOME=/root -L ./ ./bin/busybox sh -c 'cd ~ && sh'

• cd to / and run busybox ls, the root changed!

cd /
ls
bin    dev    etc    home   lib    media  mnt    opt    proc   root   run    sbin   srv    sys    tmp    usr    var

• apk is also runnable

apk add gcc

• gcc can compile a Hello World to run

gcc hello.c -o hello
./hello

Problems

There may be some problems, such as

• Some syscalls may not be relocated to rootfs

• Path may not be relocated as expected

• Hard link is not supported now

• Other problems
