Qt Creator on Fedora 25: "No valid kits found"

Question

If I try to open an existing project in Qt Creator I always get "No valid kits found".

I found a lot of Q&A around this, but on my installation I am not able to select a valid Qt version because:

In Build&Run->Kids->Desktop->QtVersion: None

I can not see any other entry in this field.

As already mentioned: It is a Fedora 25 x86_64 version.

Qt Creator gives in comand line:

Warning: No kit 'qt.57.gcc_64_kit' found. Continuing.

Is this a file which should exist somewhere? Can it be downloaded somewhere? Manual config seems to be not possible, because qt version can not be selected.

Is there any package which I did not have installed? Is there any meta package which I can use to get a valid installation?

What I have installed:

rpm -qa | grep qt5

Answer 1

The "No valid kits found" error can be caused by many things (e.g. missing g++ compiler). Here's a video I just uploaded that shows a clean install of Qt 5.13 on a clean install of Fedora 30 KDE:

Answer 2

Based on @SteeveDroz comment that worked for me on Fedora 29:

Remove the path to the shell script and select /us/bin/qmake-qt5. Now it doesn't complain about the wrong version.

Answer 3

I got it:

qtcreator was not able to find my qmake installation, because in the fedora packages qmake is:

-rwxr-xr-x. 2 root root 2921520 19. Jul 14:51 /usr/bin/qmake-qt5

Adding a softlink to

lrwxrwxrwx. 1 root root 18 5. Dez 17:17 /usr/bin/qmake -> /usr/bin/qmake-qt5

did NOT help!

You have to point to the correct qmake via :

Build&Run -> Kits -> Manual -> Desktop -> Qt-Version -> Manage -> "Select qmake with file-browser"

Now it seems to find a qt version. In "Details" the dialog prints "Qt version 5.7.0 for Desktop"

Why there is not a simple output: "Can not find qmake"?

OK, seems to be a bit special to fedora which install qmake to different file name.

Answer 4

I also develop with Qt Creator on Fedora 25, and it works for me.

Here is how I usually do it:

dnf install make gcc-c++ gdb
dnf install qt5*-devel
dnf install qt-creator

After this, I've got a working Qt Creator configuration on a fresh Fedora 25 (that I just installed from scratch yesterday).

To be honest, I'm not sure what you might have been doing wrong, but I have a few ideas:

• Did you upgrade from a previous OS version or maybe copy the configuration of a previous Qt Creator version to your new installation?
• Check that you have a compiler and build environment (make, gcc, ...) installed
• If its configuration is corrupt, you could try deleting ~/.config/QtProject and Qt Creator might recognize your stuff.
• Try to delete the *.pro.user file of your project if it may have been generated by a previous Qt Creator version

In any case, you can fix the configuration relatively easily.

• Go to Tools -> Options
• Select Build & Run
• On the Compilers tab you should see your installed compiler in the auto-detected section. If you have a compiler installed but it isn't recognized, add it here manually.
• On the Qt Versions tab, the version I installed from the Fedora repo (currently 5.7.0) appears in the Manual section (even though I didn't add it manually). You can add it by browsing to /usr/bin/qmake-qt5.
• On the Kits tab, I have a single Manual entry called Desktop, which is basically set to use the compiler and Qt version mentioned above.
