:-1: error: Project ERROR: Unknown module(s) in QT: qml

Leway Previs 0

Okay, some details first: Qt 6.2.2, on Fedora 35.

So, obvious question: how can I get hold of the QtQml module (and, to be fair, the rest of the QML modules)? I've tried the Maintenance Tool, and it seems to think they're there already.

Can you post the installation tree of your maintenance tool?

Hi and welcome to devnet,

Some more details are required:

type of project: qmake or cmake ?
how did you create the project ?

@SGaist

1: From what I can tell, qmake. (I just pressed the "Build" button, but this pops up when I modify the .pro file, before I try to build it.)
2: Not sure what you mean by this question; I've been using Qt Creator to write my project.

SGaist

Can you show the content of your .pro file ?

@SGaist, this is what it looks like. You'll note the line causing the error is in Line 1.

QT       += core gui network qml

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

CONFIG += c++11

# You can make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \
    main.cpp \
    qircbot.cpp \
    qircbotmainwindow.cpp

HEADERS += \
    qircbot.h \
    qircbotmainwindow.h

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

(As I'm sure you can tell at this point, the project in question is an IRC bot. I am not asking for advice on how to write it; this is a project that is being rebuilt from the ground up, so I've done this before, in this manner before.)

@Leway-Previs-0
run clean project, then qmake and rebuild

@aliks-os I have just done that. On Clean, it brought up that it couldn't find the QML module. Ran QMake, it showed the error in the thread title.

Now, I apologise if I sound like a jerk from this point onwards. As I stated in my original post, it cannot find the files required; it actually seems like they do not exist in my install. (And before anyone asks, yes, I looked.) What I want to know is, where can I find the files required for these modules, and what needs to be located where? That is all I needed to know.

SGaist

How did you install Qt ?
I would have guessed using the online installer in which case you should not be missing these files.

Leway Previs 0

@SGaist I did, yes.

Where would they be located normally? I'm certain I have not missed them, but y'know, best to double check. (I'm on a Linux system, if that helps.)

jsulm

@Leway-Previs-0 Maybe you also installed Qt packaged by your Linux distribution and are now using that one?
Make sure you use qmake from the Qt installation you want to use.

Leway Previs 0

@jsulm That crossed my mind also, so I did a full uninstall, then reinstalled from the Qt installer. Didn't change.
