[make Error] optional: No such file or directory

[cardboardcode]

This issue has been resolved. This post is only to record an error I faced as well as the remedy for it.

Issue Description

Running make all fails and generates make error

optional: No such file or directory

This is caused by an incompatible g++ version. The g++ version to run the command make all successfully is g++7

To check your current g++ version, run the command:

g++ --version

Solution

Install or change your default g++ version
For installing

sudo apt-get install g++-7.5
For changing
sudo update-alternatives --config g++
Then choose g++7 and above.
