Feature Request: Support for "aarch64" Arm / Armbian Linux platforms (e.g. RPi)

[aaron1138]

If reasonable as far as dependencies and maintainability, I would like to request support in the Linux installer script for SBCs like Raspberry Pi 4/5 as well as Rockchip and similar ARM / Armbian Linux (Debian Bookworm & Trixie) based SBCs. Recent SBCs often have a reasonable minimum RAM of 8/16 GB.

My use case is specifically headless operation without a UI with running UVTools scripts for file format conversion and slice image extraction as well as potentially mild amounts of utilities such as AA removal / heal and similar single layer at a time pixel math (e.g. grayscale remapping script).

If there is an existing way to install or if the preferred method is to compile from source on these platforms, please let me know and point me towards any documentation or discussions with tips and gotchas.

UVtools may be compatible with linux arm, try to compile it using the script: ./createRelease.sh -b linux-arm64 Check the publish folder and report back

Thanks, I was able to get it to build after figuring out the .NET install.

A few dependencies have moved on in the current Debian Trixie for RPi 5 platforms, so I stuffed it in a Docker container so I could use the Bookworm dependencies which Emgu.CV / libcvextern.so needed. I've only tested the extract function with UVToolsCMD so far, but I would expect the rest of the Emgu.CV functions to work properly from CLI.

Here's the working DockerFile in case it is useful to others (I have the rest of the process documented as well):

# Use the official Debian 12 (Bookworm) image for ARM64
FROM arm64v8/debian:12-slim

# Set an environment variable to prevent apt-get from asking questions
ENV DEBIAN_FRONTEND=noninteractive

# Install all the missing "not found" libraries
RUN apt-get update && \
    apt-get install -y --no-install-recommends \
    libgeotiff5 \
    libavcodec59 \
    libavformat59 \
    libavutil57 \
    libswscale6 \
    libgdiplus \
    libwebpdemux2 \
    libgtk-3-0 \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*

# Set the internal working directory
WORKDIR /app

# Copy every file from the current folder (UVtools build) 
# into the container's /app directory
COPY . .

# Set the default command for the container to be UVtoolsCmd
ENTRYPOINT ["./UVtoolsCmd"]

The custom libcvextern in UVtools should not require extra dependencies (libgeo, libtiff, etc). The compilation script is copying the custom libcvextern over (I guess), located in: UVtools\build\platforms\linux-arm64

EDIT: nvm, that is the official build, I forgot that I can't compile native arm lib for linux
