Its been quite a while since my last raspberry pi project. I went ahead and bought a new Rpi 4B and installed a fresh Raspbian OS on it and installed qt the way i remember it

$ sudo apt-get install qt5-default  #This does not work anymore i used an alternative
$ sudo apt-get install qtcreator
$ sudo apt-get install qtdeclarative5-dev

But its not as straight forward as i remember it anymore.

when i created a qt Application the desktop kit is greyed out

enter image description here

And upon further investigation it would seems that i do not have a qt version

enter image description here

Under the qt Version tab i dont have an item listed. How do i add a qt version?

enter image description here

It ask for a qmake executable and i do not know where its path is

  • qt version is the version of installed Qt – jsotola Mar 27 '22 at 17:57
  • @jsotola there is no option to pick/write anything. adding a version will ask for a file. where is that file? – DrakeJest Mar 27 '22 at 18:25
  • https://doc.qt.io/qtcreator/creator-project-qmake.html – jsotola Mar 27 '22 at 18:35
  • @jsotola yes i have read that guide, my problem is in the step 2.Select the qmake executable for the Qt version that you want to add. I do not know where that location is in my pi directory. Both options of "Add" and "Link with Qt" asks for a file/directory that i do not know where it is – DrakeJest Mar 27 '22 at 19:02
  • then, why is your title qtcreator desktop kit is greyed out ... it would make more sense to be how to find qmake executable? – jsotola Mar 27 '22 at 19:13
  • @jsotola that is indeed true, but solving the qt version might not resolve why the desktop kit is greyed out. It is only what I think would solve the problem – DrakeJest Mar 27 '22 at 19:28
  • To list installed packages, use "apt list --installed | grep -i qt" (about 60 on bullseye). To see all qt packages remove "--installed" (more than 700 packages). – Chad Farmer Apr 01 '22 at 17:41

I solved it by first running

$ which qmake

it should show you a location of qmake, now go to

Tools > Options > Kits > Qt version > Add

On the pop up, navigate to qmake location and then add. Now go back to

Tools > Options > Kits > Kit > scrool to qt version > qt 5  should now be an option there.

Although you may now solved the desktop app being grey, the project i had doesnt run because of clang. Just go ahead and install that one too

$ sudo apt install clang

  • this hasn't worked for me. i installed latest raspi 64 bit os (regular non minimal) on my raspi 4b

    Linux raspberrypi 5.15.32-v8+ #1538 SMP PREEMPT Thu Mar 31 19:40:39 BST 2022 aarch64 GNU/Linux

    I've tried sudo apt install qtcreator and the menu / preferences / add/remove software - search qtcreator, check, apply

    qmake is in the path, but when i Add it, it's a softlink that points to a nonexistent binary

    is there something else i need to sudo apt install? build-essential is already there. and several libqt5*5 libraries are installed with qtcreator
