A. 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.

 

📥 Toolchain Downloads:

Following is the table for various CI generated OS targetted precompiled Toolchain Binaries available with this project:

References:

• Host OS: on which the toolchain is executed/used.
• Target OS: for which the toolchain generates code.

📝 Note: TAR-PIGZ Compressed pre-compiled GCC Toolchain binaries can be easily be downloaded from the project's SourceForge Repository or by clicking links given in the following table.

📒 Toolchain Setup Documentation:

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

➡️ WIKI-Documentation (en-English)

 

 

B. Build-Script for Developers: Do It Yourself

• 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.

➡️ All Build-scripts are here

 

 

C. Cross-Compiling Latest QT Framework for Pi

Now, there's a steps-by-step guide available to cross-compile Latest QT for any Raspberry Pi variant/model available, using the Raspberry Pi Toolchains available with this project:

E. Bonus: Additional Toolchains Information

Supported Hardwares:

• 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.

 

Supported Programming Languages:

• C++
• Fortran
• C
• Any other language support can be easily compiled.

 

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!
