Cross-compile Python for use on armv7l

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

Installing the GNU ARM Embedded Toolchain for macOS

Introduction

The ARM Embedded Toolchain is a GNU licensed cross compiler for ARM CPU architectures, allowing you to compile C/C++ code into binaries which can execute on CPUs such as the Cortex-M line of microcontrollers.

When dealing with C/C++ embedded development, you have the choice of several compilers. Keil is probably the most well-known commercial brand in the embedded toolchain space. They have their own proprietary compiler and IDE which is quite popular for commercial applications (it's pricey and only runs on Windows).

If .DS_Store was never added to your git repository, simply add it to your .gitignore file.

If you don't have one, create a file called

.gitignore

In your the root directory of your app and simply write
