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

[SGaist]

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

[Leway Previs 0]

@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.
