# Disclaimer
There is no support or guarantees when using the provided scripts. If you break your operating system, the only remedy is to re-install your operating system and start fresh again. Use at your own risk and yes there are risks. These scripts are no maintained or supported for GCC 7, 8, 9 after CentOS SCL Yum repos are available which they are available now.
GCC 7 & 8 Compiler Scripts
===
* GCC 7.x, 8.x and 9.x compiler & Binutils build scripts for install and creation of RPMs for [CentminMod.com](https://community.centminmod.com/threads/13726/) LEMP stacks
* GCC 7.x, 8.x and 9.x snapshots are built from sources at [http://www.netgull.com/gcc/snapshots/LATEST-7/](http://www.netgull.com/gcc/snapshots/LATEST-7/) and [http://www.netgull.com/gcc/snapshots/LATEST-8/](http://www.netgull.com/gcc/snapshots/LATEST-8/) respectively using CentOS SCL devtoolset-7 provided GCC 7.2.1 compiler.
* CentOS 7.x only
* Optional support for Profile Guided Optimization based GCC builds for ~7-10% better performance for resulting binaries built
* GCC 8 as at 20180114 snapshot has [added support for new GCC Retpoline patches](https://community.centminmod.com/posts/58340/) to support new options for `-mindirect-branch`, `-mindirect-return` and `-mindirect-branch-register` to address [Spectre variant 2 vulnerabilities](https://community.centminmod.com/threads/linux-kernel-security-updates-for-spectre-meltdown-vulnerabilities.13648/).
* GCC 7.3 which is currently RC build will also add GCC Repoline patches. Once out of RC, will update script to build against GCC 7.3 branch.
Command Line Usage for install.sh
===
```
./install.sh
Usage:
./install.sh {install|install7|install8|installpgo7|installpgo8|installgcc|installgcc7|installgcc8|installpgogcc7|installpgogcc8|binutils7|binutils8}
```
Build GCC 9 RPM + Binutils RPM Only and `without` installing. If you want to install the RPM too set in `install.sh` the variable `GCC_YUMINSTALL='y'`
```
./install.sh install9
```
Build GCC 8 RPM + Binutils RPM Only and `without` installing. If you want to install the RPM too set in `install.sh` the variable `GCC_YUMINSTALL='y'`
```
./install.sh install8
```
Build GCC 7 RPM + Binutils RPM Only and `without` installing. If you want to install the RPM too set in `install.sh` the variable `GCC_YUMINSTALL='y'`
```
./install.sh install7
```
Build GCC 9 RPM only without Binutils RPM and `without` installing. If you want to install the RPM too set in `install.sh` the variable `GCC_YUMINSTALL='y'`
```
./install.sh installgcc9
```
Build GCC 8 RPM only without Binutils RPM and `without` installing. If you want to install the RPM too set in `install.sh` the variable `GCC_YUMINSTALL='y'`
```
./install.sh installgcc8
```
Build GCC 7 RPM only without Binutils RPM and `without` installing. If you want to install the RPM too set in `install.sh` the variable `GCC_YUMINSTALL='y'`
```
./install.sh installgcc7
```

```
./install.sh installpgogcc9
```
Build GCC 8 RPM only with PGO enabled without Binutils RPM and `without` installing. If you want to install the RPM too set in `install.sh` the variable `GCC_YUMINSTALL='y'`
```
./install.sh installpgogcc8
```
Build GCC 7 RPM only with PGO enabled without Binutils RPM and `without` installing. If you want to install the RPM too set in `install.sh` the variable `GCC_YUMINSTALL='y'`
```
./install.sh installpgogcc7
```
Build Binutils RPM Only without GCC RPM and `without` installing. If you want to install the RPM too set in `install.sh` the variable `GCC_YUMINSTALL='y'`
```
./install.sh binutils9
```
Build Binutils RPM Only without GCC RPM and `without` installing. If you want to install the RPM too set in `install.sh` the variable `GCC_YUMINSTALL='y'`
```
./install.sh binutils8
```
Build Binutils RPM Only without GCC RPM and `without` installing. If you want to install the RPM too set in `install.sh` the variable `GCC_YUMINSTALL='y'`
```
./install.sh binutils7
```
GCC 9 Usage
===
* `/opt/gcc-9-20191102` is symlinked to `/opt/gcc9` for easier reference as the GCC snapshot date timestamped builds increment
* Using `/opt/gcc9/enable` allows you to set PATH appropriately. Example gcc binary is at `/opt/gcc9/bin/gcc` but with source file enabled, can reference just as `gcc`
```
source /opt/gcc9/enable
```
or directly without symlink alias
```
source /opt/gcc-9-20191102/enable
```
```
ld -v
GNU ld (GNU Binutils) 2.33.1
ld.gold -v
GNU gold (GNU Binutils 2.33.1) 1.16
```
```
gcc -v

GCC 7 Usage
===
* `/opt/gcc-7-20180111` is symlinked to `/opt/gcc7` for easier reference as the GCC snapshot date timestamped builds increment
* Using `/opt/gcc7/enable` allows you to set PATH appropriately. Example gcc binary is at `/opt/gcc7/bin/gcc` but with source file enabled, can reference just as `gcc`
```
source /opt/gcc7/enable
```
or directly without symlink alias
```
source /opt/gcc-7-20180111/enable
```
```
gcc -v
Using built-in specs.

RPMs
===
Build both GCC 7 & GCC 8 RPMs (both PGO + non-PGO) and accompanying Binutils RPMs all at once
```
./install-all.sh
```
resulting RPMs saved in `/svr-setup` directory built on Intel Core i7 4790K
```
ls -lah /svr-setup | egrep 'gcc[7,8]|binutils-gcc' | grep rpm
