Linux: Import source file in AC6 use weird directory structure
You may not change and move files via your Linux file manager while you are working in Eclipse.
You cannot start editing files with gedit or any other text editor while your project is open in Eclipse.
Work from Eclipse and no where else.
The file tree in Eclipse does not necessary equate the directory structure in your file system. Please be aware of this.
As a beginner always have your libraries copied inside your project, thus NOT as external libraries or references. Later on, when you get used to dependencies these can be referenced instead.
You seem to have a funny Linux. ‘Linux being difficult about empty spaces’, I never heard of this before.
Good luck!
Greets,
