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

Where did you install Qt Creator from? The Fedora repo or the Qt project website? — Venemo, Dec 05 '16 at 16:35
Can you please give us the output of `rpm -qa | grep qt5` (maybe using a pastebin site)? — Venemo, Dec 05 '16 at 16:38

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.

Thanks. As you see in my answer qtcreator was simply not able to see my qmake. As you pointed out, qmake is installed on fedora as "/usr/bin/qmake-qt5." and qtcreator did not find it. I have to manually setup as described in my answer. — Klaus, Dec 05 '16 at 17:01
@Klaus That's interesting because I didn't have to add it manually, but it somehow still found it... Not sure how this could happen. — Venemo, Dec 05 '16 at 17:02
Yes, colleagues have done "nearly" the same installation process and have no problems ;) Maybe the Q&A will help others to find a solution if running in the same mystery. "Nearly" means: I have no idea what we did different :-) — Klaus, Dec 05 '16 at 17:05

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.

In `/use/bin`, I have `qmake-qt5.sh` (selected by default, not working) and `qmake-qt5` which works. — SteeveDroz, Feb 07 '19 at 05:43

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.

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:

I did not watch videos at all for programming questions. A well written text with some links is far enough. It feels like asking for a way to somewhere and someone sends me a video from driving this road... – Klaus Sep 23 '19 at 06:34
