How to designed the program that without UI

[victor wang]

Hi All,
I'm using QT5.5 on my computer and linux+QT for my OS system.
I wanna designed a program that can send the command to MCU via RS232.
I want to do it without any UI.
How can I do that?

Thanks in Advanced!

When creating your project, simply select "Qt Console Application".

@JohanSolo
Thanks!
But I am facing the other problem.
I can't find this file when I included.

#include <stdio.h>
#include <string.h>

This is my .pro file.

QT +=core
QT+=serialport
QT-=gui

TARGET=mcu
CONFIG+= console
CONFIG+=app_bundle

TEMPLATE=app

SOURCES+=main.cpp

Why I can't find it in QT console?
And I can find the file when i create in QT Application?

Thanks in Advanced!

AFAIK CONFIG += app_bundle is only valid for macOS, but I don't know whether it hurts (I guess not).

How did you install Qt (QT is Apple's QuickTime)?

Is is possible you don't have the dev C++ libs? Btw stdio.h is a C header, the C++ one is cstdio, and in a similar way, use cstring instead of string.h.

@victor-wang said in How to designed the program that without UI:

#include <stdio.h>
#include <string.h>

Why do you want to use C instead of C++?
If you really want do it like this

#include <cstdio>
#include <cstring>
