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!
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:
jbmaillet@jbmaillet-VirtualBox:~$ apt-cache show 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).
