Latest Set of Precompiled Raspberry Pi GCC Cross-Compilers/Native Binaries - v2.0(Fastest & Easiest Method)

09 January, 2018: Fixed Cmake issue

Summary:

This project contains the Latest Set of Precompiled Raspberry pi GCC Cross-Compilers(i.e. 8.2.0), saving your tons of time(No compiling or Error Handling needed whatsoever). Just Extract, Link & Enjoy full GCC(Raspberry Pi) functionality in your Machine. You can use it as native compiler for raspberry pi(Can be used besides old & slow 6.3.0 GCC with full C++17 support), Or use it as Cross-Compiler in any Linux Machine(Tested on Latest Ubuntu/bionic x64) to compile programs for your Raspberry Pi (Both Latest 8.2.0 & Current 6.3.0 binaries available).

Supported Raspberry Pi:

Raspberry Pi Zero/2/3 any version/model (Performance may vary)

Binaries Description: (Read Carefully)

• gcc-6.3.0-rpi.tar.bz2 - GCC Raspberry Pi Cross-Compilier version 6.3.0, works with Ubuntu(or other Linux distro)
• gcc-8.2.0-rpi.tar.bz2 - GCC Raspberry Pi Cross-Compilier version 8.2.0, works with Ubuntu(or other Linux distro)
• gcc-8.2.0.tar.bz2 - GCC Native Raspberry Pi version 8.2.0, works with Raspberry Pi 2/3 any Model(Zero not tested)

Binaries Download:

Compressed Precompiled Binary Files are available. You can easily download them from Sourceforge:(Links Below)

Extracting & Linking: (Read & Execute Carefully)

• Prerequisites (Native & Cross-Compiler):

  • Update your environment sudo apt-get update && dist-upgrade
  • Install Build-essential gawk, texinfo, git, bison sudo apt install build-essential gawk git texinfo bison

• Extracting (Native & Cross-Compiler):

  • Extract files using cmd: tar xf <filename e.g gcc-8.2.0.tar.bz2>

• Linking (Native & Cross-Compiler):

  • Move files to its correct location (ie /opt) using cmd: sudo mv <extracted folder-name e.g gcc-8.2.0> /opt
  • Properly configure paths as below(Permanently by adding it to your .bashrc):
    echo 'export PATH=/opt/<extracted folder-name e.g gcc-8.2.0>/bin:$PATH' >> .bashrc
echo 'export LD_LIBRARY_PATH=/opt/<extracted folder-name e.g gcc-8.2.0>/lib:$LD_LIBRARY_PATH' >> .bashrc

• Manage Links as below:(Native Compiler Only)
  source .bashrc
sudo ln -s /usr/include/arm-linux-gnueabihf/sys /usr/include/sys
sudo ln -s /usr/include/arm-linux-gnueabihf/bits /usr/include/bits
sudo ln -s /usr/include/arm-linux-gnueabihf/gnu /usr/include/gnu
sudo ln -s /usr/include/arm-linux-gnueabihf/asm /usr/include/asm
sudo ln -s /usr/lib/arm-linux-gnueabihf/crti.o /usr/lib/crti.o
sudo ln -s /usr/lib/arm-linux-gnueabihf/crt1.o /usr/lib/crt1.o
sudo ln -s /usr/lib/arm-linux-gnueabihf/crtn.o /usr/lib/crtn.o

• Extra step to use Cross-Compiler Binaries with Cmake: (Cross-Compiler Only)

  Enable CMake's implicit directory feature by injecting the following lines into toolchain file: (Refer Issue:#3)

  unset(CMAKE_C_IMPLICIT_INCLUDE_DIRECTORIES)
  unset(CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES)
  

That's it, Enjoy ;)

Testing: (Post Linking)

You can check Installed versions as below:

• Native Compiler(Raspberry pi):
  gcc --version
ld -v
ldd -v
• Cross- Compiler (Ubuntu x64):
  arm-linux-gnueabihf-gcc --version
arm-linux-gnueabihf-ld -v
arm-linux-gnueabihf-ldd -v

Supported Languages(full functionality):

• C++
• Fortan
• C
• Ask for other Language support.

Advantages:

• C++17 support(Native Raspberrypi GCC 6.3.0 lacks it)
• Fastest inbuilt optimization flags(Raspberry optimized GCC)
• Rediculously low installation time(few mins)
• Benchmarking Results: https://www.phoronix.com/scan.php?page=article&item=gcc-81-benchmarks&num=1

Side Note:

Building GCC 8.2.0 with the given cross compiler took about 35 minutes on my Ubuntu machine on all cores. Compare this with the straight 4~6 hours needed to build GCC 8.2.0 directly on Pi 3B+(+10 hours on Rpi2) at full CPU Load plus memory swapping needed and you will see the advantage of having a cross compiler on your main machine.
