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

Update 06, September, 2018

File Downloading is Disabled: Source files will be moved in next update to some other website as currently used Github's LFS support bandwidth limit is over.

Current Binaries:

• 8.2.0 (Cross-Compiler & Native)
• 6.3.0 (Cross-Compiler only)

Supported Raspberry Pi:

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

Supported Languages(full functionality):

• C++
• Fortan
• C

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

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).

Binaries Description:

• gcc-6.3.0-rpi.tar.bz2 - GCC Raspberry Pi Cross-Compilier version 6.3.0, works with Ubuntu x64(or other Linux x64)
• gcc-8.2.0-rpi.tar.bz2 - GCC Raspberry Pi Cross-Compilier version 8.2.0, works with Ubuntu x64(or other Linux x64)
• 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)

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.

Binaries Download:

Compressed Binary Files are already available in this repo.
You can easily download them through your Bash/Terminal:

wget https://media.githubusercontent.com/media/abhiTronix/raspberry-pi-cross-compilers/master/<filename e.g gcc-8.2.0.tar.bz2>

Extracting & Linking:

Prerequisites (Native & Cross-Compiler):

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