Issue (including debugging messages):

Sorry I'm really new to atom, coding. I really don't know what's wrong.

Just like in the picture.
There's counting of errors in the left-down corner.
But I can't see the error messages, neither the red dots before the lines.
I don't know what's wrong.

I got the similiar problem，but mine is that the linter-gcc can not check and piont out my errors.
