iNav requires a reasonably modern `gcc-arm-none-eabi` compiler. As a consequence of the long term support options in Ubuntu, it is possible that the distribution compiler will be too old to build iNav firmware. For example, Ubuntu 16.04 LTS ships with version 4.9.3 which cannot compile contemporary iNav.
As of March 2018, the recommendation for Ubuntu releases is:
As of August 2018, the recommendation for Ubuntu releases is:
| Release | Compiler Source |
| ------- | --------------- |
| 16.04 or earlier | Use the 'official' PPA |
| 17.10 | Use the 'official' PPA as the distro compiler (5.4) *may* be too old |
| 18.04 | Use the distro compiler (6.3+) |
| 18.04 | Use the 'official' PPA, as the distro compiler (6.3) was broken when last tested |
For Ubuntu derivatives (ElementaryOS, Mint etc.), please check the distro provided version, and if it's lower than 6, use the PPA.

# Using the Distro compiler
For Releases after 17.10 is is recommended to use the distro provided compiler, at least until it proves to be too old.
In case Ubuntu ever provides a modern compiler (as of August 2018, not recommended):
```
sudo apt install gcc-arm-none-eabi
```
# Using the PPA compiler
For releases prior to (and perhaps including) 17.10, the PPA compiler is used. This can be used on releases post 17.10 if you really wish to have a newer compiler than the distro default.
The PPA compiler is recommended for all cases:
```
sudo apt-get remove binutils-arm-none-eabi gcc-arm-none-eabi
