[abhiTronix]

Description

Authored by @abhiTronix abhi.una12@gmail.com

:heart: Sharing is caring.

Introducing automated, CI maintained, precompiled Raspberry Pi CPU optimized GCC Cross & Native (ARM & ARM64) Compressed Standalone Toolchains & Build-Scripts, that is fastest to setup to get quickly started with software development with Pi.

Features

Enhancements: :birthday:

• Introducing OpenSourced build-scripts for auto-generating Toolchains under GPLv3 License:
  • Implemented RTBuilder_32b: Raspberry Pi Toolchains Builder 32-bit script.
  • Implemented RTBuilder_64b: Raspberry Pi Toolchains Builder 64-bit script.
  • Introduced various user-friendly command-line parameters and helper function for scripts.
  • Introduced various environment variables for tweaking builds.
  • Replaced GZIP with PIGZ as TAR backend for faster parallel compressed builds.
• Implemented powerful Github Actions Continuous Integration(CI) environments:
  • Added new GitHub CI workflows for continuous integration with Github Action.
    • Added separate divided CI Native and Cross CLI ARM/ARM64 build-scripts to aid faster workflows.
  • Added support for various GCC versions, Models and Pi Oses.
  • Added support for Raspbian Buster(Debian 10) ARM/ARM64 Toolchains.
  • Implemented multiple Linux build matrix for each job.
  • Implemented method to auto-deployer to deploy binaries & docs to the SourceForge server.
• Added Patch and Utils scripts:
  • Implemented curl_stfp_patcher: CURL SFTP patcher script
  • Added SF_deployer: SourceForge deployer script
  • Added new bash utility script SF_docs_deployer for auto deploying docs to SourceForge Server
• Updated Docs:

Context

This project now utilizes powerful Github Actions CI(Continuous Integration) to auto-compile Compressed GCC Cross & Native ARM/ARM64 Toolchain binaries and thereby auto-deploy them to SourceForge repository. Also, source build-scripts is now going open-sourced under the GPLv3 License.
