This repository provides compile instructions for each port and how to setup the build environment used by me for my Ports. Also some inforamtion I gathered and wrote down over time.
My current build environment is a chroot inside an Ubuntu 20.04 WSL2.
Instructions how to set it up:
Install required packages on Ubuntu 20.04 LTS WSL 2
sudo apt install \
build-essential \
binfmt-support \
daemonize \
libarchive-tools \
qemu-system \
qemu-user \
qemu-user-static \
gcc-aarch64-linux-gnu \
g++-aarch64-linux-gnu
-
Download 20.04 Focal server-cloudimg-arm64-wsl.rootfs.tar.gz from Ubuntu Cloud image. https://cloud-images.ubuntu.com/releases/
-
Extract the tarball in a folder:
mkdir folder
sudo bsdtar -xpf ubuntu-20.04-server-cloudimg-arm64-wsl.rootfs.tar.gz -C folder
- Copy qemu static binary into that folder:
sudo cp /usr/bin/qemu-aarch64-static folder/usr/bin
- Start systemd with daemonize:
sudo daemonize \
/usr/bin/unshare -fp --mount-proc \
/lib/systemd/systemd --system-unit=basic.target
- Check if AARCH64 binfmt entry is present:
ls /proc/sys/fs/binfmt_misc/
- Mount and chroot into the environment:
sudo mount -o bind /dev folder/dev
sudo chroot folder qemu-aarch64-static /bin/bash
- In the chroot, delete /etc/resolv.conf file and write a name server to it.
nameserver 8.8.8.8
- Exit chroot
- mkdir -p folder/tmp/.X11-unix
- Create chroot.sh
#!/bin/bash
sudo daemonize \
/usr/bin/unshare -fp --mount-proc \
/lib/systemd/systemd --system-unit=basic.target
sudo mount -o bind /proc folder/proc
sudo mount -o bind /dev folder/dev
sudo mount -o bind /tmp/.X11-unix folder/tmp/.X11-unix
xhost + local:
sudo chroot folder qemu-aarch64-static /bin/bash
- Make the chroot.sh executable
chmod +x chroot.sh
Chroot into the new environment
sudo ./chroot.sh
- Update & Upgrade the chroot
apt-get update && apt-get upgrade
- Helpful development tools & libraries to have in the chroot
apt-get install --no-install-recommends build-essential git wget libdrm-dev python3 python3-pip python3-setuptools python3-wheel ninja-build libopenal-dev premake4 autoconf libevdev-dev ffmpeg libboost-tools-dev magics++ libboost-thread-dev libboost-all-dev pkg-config zlib1g-dev libsdl-mixer1.2-dev libsdl1.2-dev libsdl-gfx1.2-dev libsdl2-mixer-dev clang cmake cmake-data libarchive13 libcurl4 libfreetype6-dev librhash0 libuv1 mercurial mercurial-common libgbm-dev libsdl-image1.2-dev
- Install custom SDL2 Libraries for better compatiblity
rm /usr/lib/aarch64-linux-gnu/libSDL2.*
rm -rf /usr/lib/aarch64-linux-gnu/libSDL2-2.0.so*
wget https://github.com/libsdl-org/SDL/archive/refs/tags/release-2.26.2.tar.gz
tar xfv release-2.26.2.tar.gz
cd SDL-release-2.26.2/
./configure --prefix=/usr
make -j8
make install
/sbin/ldconfig
Important that you don't install libsdl2-dev package.
