SM8250 Toolchain Docker Image

Cross-compilation toolchain for Qualcomm SM8250 devices running LessOS.

Overview

This Docker image provides a pre-built toolchain for building LessUI on SM8250-based devices. The toolchain is extracted from a LessOS build and includes SDL2 and all other libraries that LessUI links against.

Usage

The image is automatically built and published by GitHub Actions to ghcr.io/lessui-hq/union-sm8250-toolchain:latest.

From the LessUI repository:

make build PLATFORM=SM8250

Local Development

make shell  # Enters the toolchain container

The container's /root/workspace is bound to ./workspace by default.
