proxmox-backup-arm64

Script for building Proxmox Backup Server 3.x for Debian/Bookworm
At least 4 GB are required for compiling. On devices with low memory, SWAP must be used (see help section).

Download pre-built packages

You can find unoffical debian packages for bookworm that are created with the build.sh script and github actions at https://github.com/wofferl/proxmox-backup-arm64/releases.

With the script you can also download all files of the latest release at once

./build.sh download

or download and install automatically

./build.sh install

or of a specific version

./build.sh download=3.2.6-1

Build manually

Install build essentials and dependencies

apt-get install -y --no-install-recommends \
	build-essential curl ca-certificates sudo git lintian fakeroot \
	pkg-config libudev-dev libssl-dev libapt-pkg-dev libclang-dev \
	libpam0g-dev

Install rustup

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs -sSf | sh -s
source ~/.cargo/env

Start build script

./build.sh 

or

./build.sh client (build only proxmox-backup-client package)

The compilation can take several hours.
After that you can find the finished packages in the folder packages/

Build using docker

You can build arm64 .deb packages using the provided Dockerfile and docker buildx:

docker buildx build -o packages --platform linux/arm64 .

You can also set build arguments for base image and build.sh options:

docker buildx build -o packages --build-arg buildoptions="client debug" --build-arg baseimage=ubuntu:jammy --platform linux/arm64 .

Once the docker build is completed, packages will be copied from the docker build image to a folder named packages in the root folder.

Build using cross compiler

Enable multi arch and install build essentials and dependencies

For cross compiling you need to enable multiarch and install the needed build dependencies for the target architecture. For the tests to work qemu-user-binfmt is needed.

dpkg --add-architecture arm64

apt update && apt-get install -y --no-install-recommends \
                build-essential crossbuild-essential-arm64 curl ca-certificates sudo git lintian \
                pkg-config libudev-dev:arm64 libssl-dev:arm64 libapt-pkg-dev:arm64 apt:amd64 \
                libclang-dev libpam0g-dev:arm64 \
                qemu-user-binfmt 

(apt:amd64 is necessary because libapt-pkg-dev:arm64 would break the dependencies without it)

Install rustup and add target arch

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs -sSf | sh -s
source ~/.cargo/env
rustup target add aarch64-unknown-linux-gnu

Start build script

./build.sh cross

Install all needed packages

Help section

Debugging

you can add the debug option to redirect the complete build process output also to a file (build.log)

./build.sh debug

Create SWAP (at least 4G on low memory systems like Raspberry PI)

from https://askubuntu.com/questions/178712/how-to-increase-swap-space/1263160#1263160

Check swap memory:

swapon --show or free -h

Change swapsize on systems with fstab enabled swap:

sudo swapoff /var/swap
sudo fallocate -l 4G /var/swap
sudo mkswap /var/swap
sudo swapon /var/swap

Change swapsize on systems with dphys-swapfile service:

sudo sed -i "s#.*CONF_\(SWAPSIZE\|MAXSWAP\)=.*#CONF_\1=4096#" /etc/dphys-swapfile
sudo service dphys-swapfile restart

400 Bad Request on Raspberry Pi 5 (wofferl#40)

The Raspberry Pi 5 uses a kernel with 16k page-size, which is incompatible with Proxmox Backup Server (jemalloc/Rust). So you need to a 4k kernel on the RPi5 for Proxmox Backup Server to work.
