Cross-compile Python for use on armv7l

Introduction

This post shows how to cross compile Python (using the [CPython][#cpython] implementation) for use on an armv7l chip. This can likely be extrapolated to other chip archetectures, but the proper cross-compilation toolchain would need to be substituded. The Python version utilized here is version 3.7.13. The driving force behind this effort was to get [python-can][#python-can] functional on an armv7l platform. This compilation process is done on a Ubuntu 20.04.4 LTS operating system. I have utilized various online references and will do my best to provide citation and links.

In my case the device with an armv7l chip contains a root file system and shared objects that are compiled using a version of [buildroot][#buildroot]. The buildroot menu configuration allows for the selection of Python 3 for installation, but not all of the basic packages are included. For example, importing the python-can package into an environment using Python 3 installed b

You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

If there's no qemu-arm-static in the package list, install qemu-user-static instead

HTML Tags You Can Use on GitHub

Wherever HTML is rendered on GitHub (gists, README files in repos, comments on issues and pull requests, ...) you can use any of the HTML elements that GitHub Flavored Markdown (GFM) provides syntactic sugar for. You can either use the syntactic sugar that GFM (or other GitHub-supported markup language you're using) provides or, since Markdown can contain raw HTML, you can enter the HTML tags manually.

But GitHub also allows you to use a few HTML elements beyond what Markdown provides by entering the tags manually, and some of them are styled with CSS. Most raw HTML tags get stripped before rendering the HTML. Those tags that can be generated by GFM syntactic sugar, plus a few more, are whitelisted. These aren't documented anywhere that I can find. Here's what I've discovered so far:

How to compile statically linked OpenVPN client for ARMv5

You need to install ARMv5 gcc cross compiler: apt-get install gcc-arm-linux-gnueabi

You have to define a directory (via --prefix) where all of your binaries will be installed (copied). In the guide I use the following: /home/user/vpn_compile
