How to install qt version?(for Linux)

kisa

@mrjj Yes. started and it appeared:

QMake has two modes, one mode for generating project files based on
some heuristics, and the other for generating makefiles. Normally you
shouldn't need to specify a mode, as makefile generation is the default
mode for qmake, but you may use this to test qmake on an existing project

Mode:
-project Put qmake into project file generation mode
In this mode qmake interprets files as files to
be built,
defaults to *; *; *; *.ts; *.xlf; *.qrc
Note: The created .pro file probably will
need to be edited. For example add the QT variable to
specify what modules are required.
-makefile Put qmake into makefile generation mode (default)
In this mode qmake interprets files as project files to
be processed, if skipped qmake will try to find a project
file in your current working directory

Warnings Options:
-Wnone Turn off all warnings; specific ones may be re-enabled by
later -W options
-Wall Turn on all warnings
-Wparser Turn on parser warnings
-Wlogic Turn on logic warnings (on by default)
-Wdeprecated Turn on deprecation warnings (on by default)

Options:

You can place any variable assignment in options and it will be *
processed as if it was in [files]. These assignments will be *
processed before [files] by default. *
-o file Write output to file
-d Increase debug level
-t templ Overrides TEMPLATE as templ
-tp prefix Overrides TEMPLATE so that prefix is prefixed into the value
-help This help
-v Version information
-early All subsequent variable assignments will be
parsed right before default_pre.prf
-before All subsequent variable assignments will be
parsed right before [files] (the default)
-after All subsequent variable assignments will be
parsed after [files]
-late All subsequent variable assignments will be
parsed right after default_post.prf
-norecursive Don't do a recursive search
-recursive Do a recursive search
-set <prop> <value> Set persistent property
-unset <prop> Unset persistent property
-query <prop> Query persistent property. Show all if <prop> is empty.
-qtconf file Use file instead of looking for qt.conf
-cache file Use file as cache [makefile mode only]
-spec spec Use spec as QMAKESPEC [makefile mode only]
-nocache Don't use a cache file [makefile mode only]
-nodepend Don't generate dependencies [makefile mode only]
-nomoc Don't generate moc targets [makefile mode only]
-nopwd Don't look for files in pwd [project mode only]

I installed qt5 again. I got it in versions but they require installing qmlscene. I installed it, but still they demand to install it and to create a new project I still can not.

Hi
So it works now for a default GUI project?

but they require installing qmlscene. I installed it, but still they demand to - install it and to create a new project I still can not.

Hi. who wants qmlscene ?
qmlscene is external program so not really sure what you mean.
Do you have some project you download that uses QML and you try to compile
it and it ask for qmlscene ?

This is how my kit look like on linux

@mrjj I can not create a single project. Everywhere some kind of kits are required which I do not have. I don’t understand where to get them.

I have a mistake , so I decided that I need to install qmlscene

I don't know if i need qmlscene or not. I just want all the work and I could create projects...

mrjj

Ok
Its a bit hard for me to see what you got due to the language of the screenshots.

In any case, it must be due to the location of qmake / gcc etc.

You must manually point the kit to qmake, the gcc and debugger where they are located in your system.

https://doc.qt.io/qtcreator/creator-targets.html

What linux is that btw ?

ps. you can ignore qmlscene is not needed for anything compiler related.

kisa

@mrjj oh sorry..
qmake, comppilera and debuggers automatically detected already.

I tried to create a new kit, but I do not have CMake and did not understand where to get it

it is not detected automatically

I use Debian, but I tried installing qt in Windows 8 and there was the same problem

mrjj

Hi
Hmm
it really looks ok now.
So if you generate a new default GUI app. it still cannot compile?

installing qt in Windows 8 and there was the same problem

Unless you choose a MinGW Qt, you must install visual studio manually.

kisa

@mrjj I can’t even create a project. Any project. On the way to the creation of the project, it is required to introduce some kit. I can not continue to create a project without kit.

On windows I already have a visual studio.
I’ve been trying to solve this problem for several days now. Please tell me, is this generally solved or am I suffering in vain?

mrjj

@kisa
Hi
Ok,
Its generally fixed by manually filling out the kits/compiler as described in those 2 docs i linked.

I dont understand why you cannot select the Default Desktop kit that is shown.
It seems valid as no yellow mark.

On windows its rarely an issue i have seen if using the correct visual studio Qt.

If using mingw Qt on Windows it should just works out of the box as all is included.

You do expand the Qt branch in installer and only installed the needed Qt versions ?

jsulm

@kisa How did you install Qt? /usr/lib/qt5 is most probably Qt from your distribution. Did you use Qt online installer?

Hi, I hope you've managed to solve you priblem, but for everyone else looking I wanted to add my solution.
I had similar problem on Debian 12. In my case I had to manually add path to qmake file in "Qt Versions" tab, and then I choose my new added version in "Qt version" field, while in settings on your Desktop(default) kit.
And that's pretty much it, i was able to select this kit while configurating and build my project
