No header generated with uic

QtCreator doesn't want to create my ui header file. When I enter uic in the terminal it says me this : 

louis@Krusty:~$ uic
uic: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/uic': No such file or directory

I have Qt5 installed in my home folder, Qt recognized it without issue. In the settings, it's in the good folder. Normaly it shouldn't has any problem ! But it has, so I have to create my form by hand : 

./.Qt/5.5/gcc_64/bin/uic Documents/lab/Qt/OpenPlane/AirplaneEditor.ui  -o ui_AirplaneEditor.h

This is my QMake :

QT += widgets

SOURCES += \
    main.cpp \
    Airplane.cpp \
    AirplaneOverview.cpp \
    AirplaneManager.cpp \
    AirplaneEditor.cpp

HEADERS += \
    Airplane.h \
    AirplaneOverview.h \
    AirplaneManager.h \
    AirplaneEditor.h \
    ui_AirplaneEditor.h # By hand

FORMS += \
    AirplaneEditor.ui

If you need more informations, ask me!

The problem in question disappeared after installing two packages: qtbase5-dev-tools qtbase5-de (Ubuntu 22.04)

I had the same problem. All my Qt5 packages are installed but uic cannot be found on my linux (CentOS) system, but uic-qt5 is!

So executing the following worked for me:

$ uic-qt5 AirplaneEditor.ui -o ui_airplaneeditor.h

From the usefull comments from @bibi:

Looks like your PATH does not include ~/.Qt/5.5/gcc_64/bin/, and/or not before the regular paths. As bibi said, what is the output of "which qmake uic"?

Type on a terminal:

export PATH=$HOME/.Qt/5.5/gcc_64/bin/:$PATH

(some others path may be needed) and then run agin from this terminal. If it does the trick add this PATH addition to you ~/.bashrc to make it permanent.

But the root problem as I see it is why did you installed Qt5 manually??? (and why in hidden directory?) I you do really need a custom version of Qt, that would not be installed among your system files, a better install place could be /opt. Plus the matching PATH settings explained above.

If you do not need a custom Qt, every Linux distro can happily install Qt4 and Qt5, and you can then chose which version to use in your .pro file as is exemplified here:

How to check the selected version of Qt in a .pro file?

EDIT:

"I installed it with the official installer from Qt. How should I install it on Ubuntu 15.10?"

The regular way is definitely not to install it from some Qt's archive. You have a distribution with packagers/maintainers, you should trust them. So for a Qt4 install that would be sudo apt-get install qt-sdk. For Qt5 I don't know, but a bit of apt-cache search qt5 and/or googling should do the trick.

EDIT 2:

For a Qt5 install, at least on my virtualbox Ubuntu 14-04 (I run Debian), the base package would be something like qtbase5-dev:

Look at the list of dependencies it will install: qt5-qmake, qtbase5-dev-tools, the libs etc.

So apt-get install that, plus latter on maybe a few more packages depending on the type of Qt5 app you want to develop (ex Qt5 with dbus or this or that).
