Qt 6 is Frustrating

[ofmrew]

I loaded qt6, finally on Mint Linux, but now I cannot use it. (1) Trying to run a example program, but there are no kits available and the documentation leads me to nowhere. Where can I find out how to load kits? (2) I also installed TexMaker but it seem that Qt is getting the F1 key and not TexMaker. Any thoughts or pointers?

Hi,

Not knowing how you installed it and what version of Qt Creator your have I do not know why it's not automatically loaded.

As for adding kit, here is the related documentation from Qt Creator.

[ofmrew]

QT6 was installed using the online open source installer and the Qt Creator opened because the box was checked at the finish of the installation.

@ofmrew said in Qt 6 is Frustrating:

there are no kits available

Basically, a "kit" = "Qt version" + "compatible compiler"

Do you have g++ installed? Qt is a C++ library, so it needs a C++ compiler.

PrefixPath: /home/bob/Qt/Tools/QtCreator/lib/Qt

This points to libraries used by the Qt Creator application. This is different from development libraries that you need to build applications.

Which version of Qt did you install? See screenshots below for possible choices:

[ofmrew]

@JKSH Qt 6.0.1. Should I have loaded Desktop gcc 64-bit also.

@ofmrew said in Qt 6 is Frustrating:

Qt 6.0.1. Should I have loaded Desktop gcc 64-bit also.

To get a complete kit, you need to have installed:

• Qt > Qt 6.0.1 > Desktop gcc 64-bit (from the Qt installer)
• g++ (from your Linux distro's repo)

You can launch the MaintenanceTool from your Qt folder to modify your Qt installation.

[ofmrew]

@JKSH I did what you asked and on compiling a program known to work:

It looks like something is wrong with the kit. Any ideas, I hope so because it looks like we are getting close.

[SGaist]

No, your kit is fine, you are missing the OpenGL development libraries from your distribution. Just install the corresponding dev package and you'll be good to go.

[ofmrew]

@ofmrew It worked! I found and executed this:
Enter sudo apt-get update
Enter sudo apt-get install freeglut3
Enter sudo apt-get install freeglut3-dev
Enter sudo apt-get install binutils-gold
Enter sudo apt-get install g++ cmake
Enter sudo apt-get install libglew-dev
Enter sudo apt-get install mesa-common-dev
Enter sudo apt-get install build-essential
Enter sudo apt-get install libglew1.5-dev libglm-dev

I want thank for for your help and tolerating my questions. Next I will try to install qt3d using Conan. So I most likely have questions. Again thanks.

[SGaist]

Great !

Since you have this part working, please mark the thread as solved so that other forum users may know a solution has been found :-)
