Make executable file run without prompt in linux

Question

Every time I ran an executable installed in the system it's all fine without any prompt, but recently I configured my vim editor to do c++ coding. Every time I build a program using make through vim and want to run the built executable, a pop up shows that this file is an executable and whether I want to execute it??

How do I turn that thing off so that no prompt will annoy me?

edit: The prompt appears only when double clicking the file outside the vim editor. using LXDE desktop on debian.

edit: I noticed that any executable file double clicked in file manager gets the same pop up. when launching the app through the desktop panel it is fine.

Answer 1

I don't know what you did when you "configured vim to do c++", but you should simply be able to build either with a make file by running :make or with g++ directory by calling:

:!g++ % -o %<  # calls gcc filename.ext -o filename

Then in like manner to run the compiled program:

:!./%<         # executes ./filename  (w/o extension) and without prompting

Answer 2

Are you on ubuntu? If so, try open preference of the file, find behavior options, choose execute it when open.
