I would like to learn Arduino language, because I think it's easy! it is C/C++.

You need to specify the path to the tools-builder folder, which is where ctags is. Try this: arduino-builder \ -compile \ -hardware /usr/share/arduino/hardware \ -tools /usr/share/arduino/hardware/tools \ -tools /usr/share/arduino/tools-builder \ -libraries lib \ -fqbn arduino:avr:uno \ -build-path .build \ src/main.ino

I don't understand why this worked, but I found this comment in Redhat Bugzilla (it doesn't seem to be a bug report specifically about that...but anyway): Parameter 'tools' is mandatory [...] However, if I create the packages directory in ~/.arduino15, compilation now works. mkdir ~/.arduino15/packages Seemed like an easy thing to try, ...

The Arduino itself is open, and you can use it to make commercial products. Note however, that for commercial products, a lot of additional requirements may be needed (regulations, safety, certifications), especially since it will be used in public places among (many) other people. You don't want students to be injured/die because of a badly designed device....

The problem occurs because arduino does not have permission to modify directory in /usr/share/arduino to create tools-builder All you have to do is navigate to usr/share/arduino create 'tool-builder' directory sudo mkdir /usr/share/arduino/tools-builder

I found the offending file in a sub directory of the C:\Software sketch directory. I had a subdirectory called trash, and the Arduino build found it from there, and put it in AppData then referenced the error from there.
