Can I use Qt Creator for non-gui programming on C?

Question

Can I use the Qt Creator IDE for non-GUI programming? Now, compiling "Hello world" like plain C project:

#include <stdio.h>
int main(void)
{
    printf("Hello World!\n");
    return 0;
}

I get an error

:-1: error: Circular all <- project dependency dropped.

What did I do wrong?

I found the solution. In Tools - Options - Environment in Terminal a wrote xterm -e and it worked :) Thanks for all.

What happens if you add the required #include <stdio.h> to the top? — Keith Thompson

In my .pro file doesn't QT += core. I added in the .pro QT -= core, but I get error again. — milssky

I've been using QtCreator for writing a console app in C. I just have the following at the top of the project file:

TEMPLATE = app
CONFIG += console
CONFIG -= qt

And then the usual stuff to include sources (eg, SOURCES += main.c). Seems to work fine.

Theorically you can do this. All C programs are supposed to compile in C++.

Well... For example, the function declaration void f() means different things in C and C++, so the call f(0), while valid in C, won't compile in C++.

No, not all C programs are valid C++ programs. For example, int class; is a legal C declaration, but a syntax error in C++.

@myrkos: Correct -- but it's close, and apart from the missing #include <stdio.h> the OP's C program is valid C++.

QT has special class for non-gui apps, it's called QCoreApplication.
