This directory contains scripts for release build of Python artifacts for Linux platform. We use manylinux2014 (PEP599) for Python Linux distribution: Manylinux GitHub repo.

Python packages are built inside Docker containers. For x64 architecture quay.io/pypa/manylinux2014_x86_64 is used.

Due to the lack of Linux aarch64 support from Kotlin Native KT-36871, the Docker image for aarch64 packages build (quay.io/pypa/manylinux2014_aarch64) must be run on a x64 host. To do this, you need to build the arm64 image manually with the addition of the qemu-user-static util.

• run_manylinux_docker.sh - runs Docker 'manylinux' containers (script runs automatically).
• build_manylinux_wheel.sh - builds Python wheels inside 'manylinux' containers (script runs automatically).
• manylinux-arm-image - contains files, needed to build cross-arch manylinux image:
  • Dockerfile
  • build_image.sh - builds manylinux_aarch64 image, which can be run on x64 host.

Normally run_manylinux_docker.sh is launched by build_release.py script, but it also can be run manually from the project root:

./tools/run_manylinux_docker.sh <arch>

where <arch> is x86_64 or arm64

You should have Docker installed on your Linux build host: Instructions

Install QEMU packages on your system (for Ubuntu):

sudo apt update
sudo apt install qemu binfmt-support qemu-user-static

Run multiarch/qemu-user-static Docker image for QEMU script registering:

docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

Copy qemu-aarch64-static script to the manylinux-arm-image folder:

cp /usr/bin/qemu-aarch64-static ./manylinux-arm-image/.

Run manylinux_aarch64 image build by shell script:

cd manylinux-arm-image
./build_image.sh

Your Linux build host is ready for Lets-Plot release build.
