No header generated with uic

Question

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!

What do you mean by _"... doesn't want ..."_? Did you get en error? Also, if doing it manually is okay, so what's your problem? Your question at the moment seems fairly unclear, please [edit](http://stackoverflow.com/posts/35823061/edit) it and elaborate on it in a clear way. — frogatto, Mar 06 '16 at 07:07
Are you sure you called the qmake you have installed in your home? what is the output of `which qmake uic` and does the makefile get created? The rule for your ui is correct? — bibi, Mar 06 '16 at 07:19
Note: It's a bit strange to install QT in `~/.Qt` it is supposed to be a _hidden_ directory. What os are you on? — bibi, Mar 06 '16 at 07:24
Okay so `which qmake uic` said me that they are in the `/usr/bin`. Wtf? I installed it with the official installer from Qt. How should I install it on Ubuntu 15.10? — Louis Etienne, Mar 06 '16 at 07:55
I don't want to generate the header by hand. Normaly it does it automatically! — Louis Etienne, Mar 06 '16 at 07:56
ok, that's what I was wondering. You have a System installed qt and a manual one. I suggest to keep just one, so uninstall the system one. You can make them work together but it requires some (minimal) skills. Anyway, to compile run the qmake you have in your home. This should be something like `~/.Qt/5.5/bin/qmake` — bibi, Mar 06 '16 at 08:02
It looks like you have more than one version of Qt installed. The error message seems to be referring to Qt4, not Qt5 — RobbieE, Mar 07 '16 at 06:59

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).

Okay, so during you was posting this post, I deleted the `.Qt` and reinstall it. Now I start from a new installation. But it still doesn't work. :( — Louis Etienne, Mar 06 '16 at 08:17
There is no Qt5 package. I have to install it from official installer (On the Qt5 wiki) — Louis Etienne, Mar 06 '16 at 08:22
@Wizix trust me, **there are Qt5 dev packages in Ubuntu 15.10 wily** : https://launchpad.net/ubuntu/wily/+package/qt5-default. "Qt 5 development defaults package". So use this instead, else you're on your own and you have a simple PATH problem to begin with, and maybe more troubles latter. — jbm, Mar 06 '16 at 08:39
@Wizix ...as an example of troubles you'll have latter on by doing such custom install, not only will you need to setup your `PATH`, but also latter on setup a `LD_LIBRARY_PATH` env var to run your app from a shell outside of Qt Creator. No, really, this is not the way to go. — jbm, Mar 06 '16 at 08:47

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
