## Summary:
9-
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*).

28-
**1. Prerequisites (Native & Cross-Compiler):**
29-
* Update your environment `sudo apt-get update && dist-upgrade`
30-
* Install Build-essential gawk, texinfo, git, bison `sudo apt install build-essential gawk git texinfo bison`
31-
32-
**2. Extracting (Native & Cross-Compiler):**
33-
* Extract files using cmd: `tar xf <filename e.g gcc-8.2.0.tar.bz2>`
34-
35-

### Important:
118-
To restore old configration(Only, if you followed step-6), download this script [Restore_old_6.3.sh](https://github.com/abhiTronix/raspberry-pi-cross-compilers/blob/master/Tools/Restore_old_6.3.sh)(_right click and "Save As"_) and execute:
119-
120-
```
121-
chmod +x Restore_old_6.3.sh

## Advantages:
134-
- C++17 support(Native Raspberrypi GCC 6.3.0 lacks it)
127+
- Fully Raspberry Pi Optimized and Improved Performance [Benchmarking Result](https://www.phoronix.com/scan.php?page=article&item=gcc-81-benchmarks&num=1)
128+
- C++17 support (Default Raspberry pi GCC 6.3.0 lacks it) and Other [Major Changes](https://www.gnu.org/software/gcc/gcc-8/changes.html)
135129
- Fastest inbuilt optimization flags(Raspberry optimized GCC)
136-
- Rediculously low installation time(few mins)

### Side Note:
140-
*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.*
