@knudlf I did run that command but it didn't fix anything. So, I had to call it
a day and I shutdown the computer.
And then today morning, I just couldn't login. Things were horribly broken.
Then I took a backup of my data and reinstalled Ubuntu.
Now when I ran the make, all previous errors disappeared. I solved the new errors
and something has compiled here now.

All this is about compiling JUCE programs.
