Precompiled Toolchains: Easy-to-Use

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.

Identifying Toolchain Binaries by Name:

You can easily identify each pre-compiled toolchain binary by its name as follows:

To get the location of each Binary of this project on SourceForge, you can also check out this Reference Tree.

Toolchain Setup Documentation:

These precompiled toolchains setup requires just three easy steps - Downloading, Extracting and Linking:

Supported Toolchains Programming Languages:

C++

Fortran

C

Any other language support can be easily compiled.





Build-Script for Developers: Do It Yourself

Open-Source is awesome

This project now provides user-friendly open-sourced bash build-scripts that auto-generates Compressed Cross & Native GCC ARM & ARM64 Toolchain binaries targeting Raspberry Pi 32-bit & 64-bit OSes.

If you need additional language support or need to compile another suitable GCC version toolchains for your Raspberry Pi, then you can use these scripts to manually compile any GCC toolchains by running suitable build-scripts yourself through your system terminal.

You can find complete information about these build-scripts here

Additional Information

Supported Devices:

All Raspberry Pi hardware/versions/models are currently supported.

Any other ARM & ARM64 Device (such as Android, other SBCs, IoT etc.) with similar or compatible Hardware architecture(see Optimization Flags), should also work.

Optimization Flags Involved:

These toolchains are built with these following system-specific LTO (Link Time Optimization) flags, therefore you can easily take advantage of your Raspberry Pi's CPU specific features with these Toolchains while compiling your programs:

Raspberry Pi Board Link Time Optimization Flags Raspberry Pi - Zero/W/WH & 1 Model A/B/A+/B+ -march=armv6 -mfloat-abi=hard -mfpu=vfp Raspberry Pi - 2 & 3 Model A/B -march=armv7-a -mfloat-abi=hard -mfpu=neon-vfpv4 Raspberry Pi - 3 & 4 Model A+/B+ & Compute 3/3-lite/3+ (32-Bit) -march=armv8-a -mfloat-abi=hard -mfpu=neon-fp-armv8 Raspberry Pi - 3 & 4 Model A+/B+ & Compute 3/3-lite/3+ (64-Bit) -march=armv8-a+fp+simd

Raspberry Pi 4+: The latest Raspberry Pi 4 uses a Broadcom BCM2711 SoC with a 1.5 GHz 64-bit quad-core ARM Cortex-A72 processor, that also have armv8-a architecture similar to Raspberry Pi 3B+, therefore it is also officially supported!
