How can I compile a C program file which I created using the Libre Office editor?

Question

I'm new to Linux and I need some help!

I am trying to compile the code taken from this post to the linux-kernel mailing list.

I have pasted the file into Libre Office and saved it as pairing_tool.c (Not as pairing_tool.c.odt. I have renamed the file to pairing_tool.c.)

But when I use this command line: gcc -o pairing_tool pairing_tool.c in the terminal, I get many errors.

• What did I do wrong?
• Should I paste the text into a special text editor?

Also just to be clear, I've used the text included only in between

#include <linux/input.h>

and

return 0;
}

So I haven't put the comments. I think it is good this way, is it?

Yes, you should use a text editor, for example gedit which is installed in Ubuntu by default. LibreOffice Writer is a text processor and it saves its files with some additional markup which C compiler does not understand.

To run gedit, press the Super (Win logo) key and type "gedit".

Apart from saving the program in plain text format, you will also need to install the C compiler and stuff, which you can do with

sudo apt-get install build-essential

(although I think you already managed to install it)

Btw, I can confirm that the program compiles nicely and even runs after that :)
