QMake doesn't work properly

[Johnnyk91]

@jsulm Hi

I've just checked with

sudo dpkg --list

and it is installed.

I've also found the directory with the Qt Headers QApplication, QObject, etc...

Hi,

Just an educated guess but check the qmake version. It's possible that you are currently using a Qt 4 qmake.

[Christian Ehrlicher]

--> qmake -v to get the qmake version

and maybe qmake -d <foo>.pro to see what exactly happens.

[Johnnyk91]

@SGaist By running the command

qmake -v

I get this

QMake version 3.1
Using Qt version 5.12.8 in /usr/lib/x86_64-linux-gnu

@Christian-Ehrlicher By running the command

qmake -d <foo>

I get this

bash: syntax error near unexpected token `newline'

[SGaist]

That looks good.

What do you get if you just call "qmake project.pro" without any other parameters ?

[Johnnyk91]

@SGaist The terminal doesn't display any message.
The Makefile generated is the same.

@Johnnyk91 said in QMake doesn't work properly:

qmake -d <foo>

I get this
bash: syntax error near unexpected token `newline'

You did not really put 'qmake -d <foo>' into your command line and wondered that it did not work? Do you???

[Johnnyk91]

@Christian-Ehrlicher I don't know what you mean but I tried

qmake -d

and I got a lot of lines starting with DEBUG 1

Make sure the development packages are installed, that is qtbase5-dev and qtbase5-dev-tools.

[Johnnyk91]

@kshegunov Thank you for your suggestion. I turned off my computer. I'll check tomorrow and come back to you.

[Johnnyk91]

@kshegunov I've just checked and they were already installed.

You have installed the runtime packages.

As @kshegunov said, you must also install the development packages.

[Johnnyk91]

@JKSH Are the development packages qtbase5-dev and qtbase5-dev-tools ?

Ah, sorry... I just noticed that you do have qtbase5-dev and qtbase5-dev-tools installed. OK, you already have the development packages.

Next thing to try: Install Qt Creator and see if you can use it to build an application.

[Johnnyk91]

I've managed to fix it.

I set the variable CONFIG to debug in my project file and I think that's why the modules weren't added.
I took this line off and I was able to compile and run my program.

Thank you for trying to help me

[SGaist]

If you did something like

CONFIG = debug

You, in fact, nuked the content of the variable and replaced it with debug.

If you want to modify the content of such a variable, use either += or *=. The first to add a value and the second to add the value only if not already in the variable.
