build-scripts

 

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 manually compile any GCC toolchains by running suitable build-scripts yourself through your system terminal.

RTBuilder_32b: Raspberry Pi Toolchains Builder 32-bit

• This script auto-generates Compressed Cross & Native GCC ARM Toolchain binaries targeting Raspberry Pi 32-bit Stretch(Debian 9) & Buster(Debian 10) OSes.

RTBuilder_64b: Raspberry Pi Toolchains Builder 64-bit

• This script auto-generates Compressed Cross & Native GCC ARM64 Toolchain binaries targeting any Raspberry Pi 64-bit Stretch(Debian 9) & Buster(Debian 10) OSes.

 

Usage

You can run these bash scripts to manually compile any GCC toolchains version through your system terminal:

---

Important ⚠️

• For downloading artifacts these build-scripts requires an active Internet connection.

• These build-scripts supports Linux-machines only.

---

1. Update environment & Install prerequisites:

   # update your system
   sudo apt update && sudo apt dist-upgrade
   
   # install prerequisites
   sudo apt-get -y install gcc g++ gperf flex texinfo gawk gfortran texinfo bison \
       build-essential openssl unzip wget git pigz \
       libncurses-dev autoconf automake tar figlet

   Optional: Install ccache for speeding up build time:

   # Install package
   sudo apt install -y ccache
   
   # Update symlinks
   sudo /usr/sbin/update-ccache-symlinks
   
   # Perpend ccache into the PATH
   echo 'export PATH="/usr/lib/ccache:$PATH"' | tee -a ~/.bashrc
   
   # Added related env variables
   export CCACHE_COMPRESS=1
   export CCACHE_DIR=$HOME/.ccache
   
   # Source .bashrc to test the new PATH
   source ~/.bashrc && echo $PATH
   

2. Clone this repository:

   # clone repository
   git clone https://github.com/abhiTronix/raspberry-pi-cross-compilers.git
   
   # call directory
   cd raspberry-pi-cross-compilers/build-scripts
   

3. Run scripts:

   RTBuilder_32b: Raspberry Pi Toolchains Builder 32-bit

   • Usage parameters: This script requires a few command-line parameters, just run ./RTBuilder_32b on terminal:

     Usage: ./RTBuilder_32b -g [GCC version] -r [Target Pi type] -o [Target Pi OS type] -V
         -g GCC version you want to compile?: (7.1.0|7.2.0|7.3.0|7.4.0|7.5.0|8.1.0|8.2.0|8.3.0|9.1.0|9.2.0|9.3.0|10.1.0|10.2.0)
         -r What's yours Target Raspberry Pi type?: (0-1|2-3|3+)
         -o What's yours Target Raspberry Pi OS type?: (stretch|buster)
         -V Verbose output for debugging?
     

   • Usage: Just pass targeted GCC version to -g parameter, targeted raspberry pi type to -r parameter, and targeted raspberry pi OS type to -o parameter of this script:

     ⚠️ You must NOT compile GCC version less than GCC 8.3.0 for Buster OS, otherwise script will automatically switch to build for Stretch OS.

     chmod +x RTBuilder_32b
     ./RTBuilder_32b -g "9.3.0" -r "2-3" -o "buster" -V
     

     This will take some time (approximately 55mins on 8cores), so grab a coffee ☕. On returning you will find native-gcc-{GCC_VERSION}-pi_{PI_TYPE}.tar.gz and cross-gcc-{GCC_VERSION}-pi_{PI_TYPE}.tar.gz at your $HOME directory.

    

   RTBuilder_64b: Raspberry Pi Toolchains Builder 64-bit

   • Usage parameters: This script requires few command-line parameters, just run ./RTBuilder_64b:

     Usage: ./RTBuilder_64b -g [GCC version] -o [Target Pi OS type] -V
         -g GCC version you want to compile?: (7.1.0|7.2.0|7.3.0|7.4.0|7.5.0|8.1.0|8.2.0|8.3.0|9.1.0|9.2.0|9.3.0|10.1.0|10.2.0)
         -o What's yours Target Raspberry Pi OS type?: (stretch|buster)
         -V Verbose output for debugging?
     

   • Usage: Just pass targeted GCC version to -g parameter of this script:

     chmod +x RTBuilder_64b
     ./RTBuilder_64b -g "9.3.0" -V
     

     This will take some time (approximately 55mins on 8cores), so grab a coffee ☕. On returning you will find native-gcc-{GCC_VERSION}-pi_64.tar.gz and cross-gcc-{GCC_VERSION}-pi_64.tar.gz at your $HOME directory.

 

Additional Environment Variables:

These scripts provide a few additional environment variables to tweak Toolchain Builds:

• BUILDDIR: To change build directory. By default it is set to temp(/tmp) directory. Its usage is as follows:

  ⚠️ Make sure assigned directory has read/write permission.

  BUILDDIR="/home/foo/foo1"

• LANGUAGES: To change supported programming languages for your Toolchains. Its default value is c,c++,fortran. Its usage is as follows:

  ⚠️ Make sure to install additional dependency manually according to your assigned supported languages.

  LANGUAGES="c,go,brig,d"

 

Supported GCC Versions:

These scripts only support newer GCC versions, those are as follows:

GCC Version	Stretch OS build (32/64-bit)	Buster OS build (32/64-bit)
7.1.0	supported	x
7.2.0	supported	x
7.3.0	supported	x
