📝 Toolchains Setup Instructions

To avoid Undesired errors & compatibility Issues, strictly follow the steps given below :

A. Raspberry Pi GCC Native-Compiler ARM Toolchains:

These ARM toolchains can be used directly on any Raspberry Pi 32-bit OSes for compiling programs for it.

• Stretch: Used and generate code for Raspbian Stretch 32-bit OS (a.k.a Debian Version 9) and any equivalent OS only.
• Buster: Used and generate code for Raspbian Buster 32-bit OS (a.k.a Debian Version 10) and any equivalent OS only.
• ➡️ Toolchain Setup Guide >>

 

B. Raspberry Pi GCC Cross-Compiler ARM Toolchains:

These ARM toolchains can be used on any x86/x86_64 Linux Distributions for cross-compiling programs for Raspberry Pi 32-bit OSes.

• Stretch: Generates programs for Raspbian Stretch 32-bit OS (a.k.a Debian Version 9) and any equivalent OS only.
• Buster: Generates programs for Raspbian Buster 32-bit OS (a.k.a Debian Version 10) and any equivalent OS only.
• ➡️ Toolchain Setup Guide >>

 

C. Bonus Raspberry Pi GCC 64-Bit ARM64 Toolchains:

This project now provides exclusive 64-bit ARM64 (aka AArch64) Raspberry Pi GCC Toolchains. These ARM64 toolchains can be used to compile programs for any Raspberry Pi 64-Bit OS flavors with 64-bit kernel (such as Raspbian Buster 64-bit OS and Pi64 by @bamarni) .

💡 Supported Pi Models: These toolchains can be used with any Raspberry Pi Models/Versions with ARMV8-A CPU Architecture that supports 64-Bit execution state. You can find complete all supported Pi's list here.

C1. Raspberry Pi GCC 64-Bit Native-Compiler Toolchains:

These ARM64/AARCH64 native toolchains can be used directly on any Raspberry Pi 64-Bit OS flavors with 64-bit kernel only (such as Raspbian Buster 64-bit OS) for compiling programs for it.

• Stretch: Used and generate code for Raspbian Stretch 64-bit OS (a.k.a Debian Version 9) and any equivalent OS only.
• Buster: Used and generate code for Raspbian Buster 64-bit OS (a.k.a Debian Version 10) and any equivalent OS only.
• ➡️ Toolchain Setup Guide >>

C2. Raspberry Pi GCC 64-Bit Cross-Compiler Toolchains:

These ARM64/AARCH64 cross-compiler toolchains can be used on any Linux Distributions (32-bit/64-bit) for cross-compiling programs for any Raspberry Pi 64-Bit OS flavors with 64-bit kernel only (such as Raspbian Buster 64-bit OS).

• Stretch: Generates programs for Raspbian Stretch 64-bit OS (a.k.a Debian Version 9) and any equivalent OS only.
