I installed brew installed qt and qt-creator.
When trying to create a new qmake empty project I get stuck on the Kit selection page saying that no valid kits were found, and can't go any farther. I tried searching the web but I did not find my answer.
Can anyone help me please?
Thanks !
Well even I had the same problem, but it was because during the installation process you have to select the Qt version and then do the installation. This installs all the necessary components but increases the file size.

I have newly installed Qt and when I tried to open my projects and have not even tried to compile, I got this mysterious cannot find feature windows_vulkan.
My QT has been working earlier but I had to reinstall it because it complained I had missing libicuun65.dll and libicuuc65.dll and recommended reinstallation. I have removed everything and installed qt from scratch.
Below is my error
I went into the directory it specified and clearly see the file. I am just not sure the content of the file is complete as it only contains 2 lines below:
load(windows_vulkan_sdk)
QMAKE_LIBS_VULKAN =
Maybe there are lib that are missing like libicuun65.dll and libicuuc65.dll and/or others?
Also, please note the uncompleted "Prepare C++ code Model" status bar. It has never completed as I saw it there for hours...it should not take that long.
What should I do to rectify this issue? Please help.
Update: My paths are set up too...
I think I understand why this happens for you, you install your Qt in Drive D but install Vulkan SDK in Drive C.
These should be on the same Drive.
Maybe Qt can't find your Vulkan SDK because of that please reinstall Vulkan SDK in Drive D.
another thing is this link in bugreports.qt.io
and also this GitHub issue.
They have problems like you and their compiler was MSYS2.
In
\msys64\mingw32\qt5-static\share\qt5\mkspecs\common\windows-vulkan.conf
changed:
From: load(windows_vulkan_sdk)
To: load(win32/windows_vulkan_sdk)
I want to view Qt reference documentation inside QtAssistant, but the installation of Qt5 did not come with .qch documentation files for Qt libraries.
I have tried to find them on the http://qt-project.org but could not find them anywhere.
How do I get the Qt5 documentation files ?
I am using Ubuntu 12.10, I have installed the new qt-library sdk from the qt-project website.
Open Assistant (5.0.1/gcc/bin/assistant) and then go to Edit -> Preferences menu.
There's a Documentation tab. If the list is empty, add the .qch files found in the 5.0.1/gcc/doc/ directory.
This is how it looks. This is Ubuntu 12.10 as well.
Qt 5.0.1 installed with the qt-linux-opensource-5.0.1-x86-offline.run package (388Mb).
Yes, the official Ubuntu-documentation for Qt5 is very incomplete. You don't have information about nearly any class.
If you want to use the QtCreator/QtAssistant build from Ubuntu you have to acquire the docs yourself. I did and uploaded these on my personal Mega-account. Here are the docs. I installed the Qt framework with the installer from qt-project.org, grabbed the documentation and inserted it into the software-center-version.
I don't use QtAssistant as a stand-alone program but integrated in QtCreator. To add the docs to QtCreator go to Tools>Options>Help>Documentation and click add. Then select all .qch files, click apply and enjoy. Maybe try the way as mentioned above.
After all, you can just download the necessary *.deb file from the store of the Ubuntu packages, and install it on your system. As they wrote here, this package will install the *.qch files in /usr/share/qt5/doc. The pitfall is that you will have to remember that you have done that, since your Ubuntu will not take any records for you.
I am new to Qt and its IDE Qt Creator so pardon my ignorance.
When I try to compile my code I get the exception
"Qt Creator needs a compiler set up to build. Configure a compiler in the kit options".
I have installed MingGW for compiling C++ code.
However, I am having a problem configuring it for Qt Creator.
Any help will be appreciated. Thanks
I suspect you are using the new 5.0 Qt. It required a bit of prodding for me too.
If you look into Settings > Build & Run > Kits you should see an auto-detected entry which will probably have an exclamation mark in front and is not editable. Ignore this.
Add a new Kit
Give it a name, set the "Qt version" and select a compiler. (Compilers should have been auto-detected. If you do not see any compilers, you will have to set at least one up manually)
Click the "Make Default" button. (You may have to modify project build settings to use the new Kit too)
There may be a better way, but I do not know it. And you should probably use 4.x until 5 is out of beta.
I was also having the same problem, so what I did was this:
sudo apt-get install g++
sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev
I then closed the QT Creator, restarted it, and it worked.
I do not know which of the above two made it work, but it worked!
You are using Qt Creator 2.6.x, as those are the only ones that have kits.
Please go to Tools>Options>Build & Run>Compilers and add you mingw compiler there. You need to point creator to 'g++' in your mingw installation.
Then head over to the Kits tab and click on the desktop kit that creator should have created for you. In the details there is a field called Compiler (or Tool chain, don't remember). Select your mingw compiler there. Check the debugger field. If it is empty or using the gdb debugger that is part of mingw: Grab a debugger from http://builds.qt-project.org/, install it and point creator to that one. The debuggers delivered as part of mingw are known to not work well with creator.
Do not use the Nokia Qt SDK: Everything in there is terribly outdated by now!
This is just a starting point to troubleshoot your question, but the Qt Creator preferences has settings in the "Build & Run" area where you can define the location of your build toolchain: compiler, Qt version to build, etc. For mingw you'd have to point the right field to the location of g++, for a Qt version the location of qmake.
Not always the last version is the better. If someone is learning Qt to implement production solutions, is not good idea to use Qt version 5 (see the Qt5 change log). If you want to learn Qt programming, I think that the Nokia SDK is a good starting point, because you only have to install it as another Windows software, and start to coding.
By using linux is another good starting point, because you will have all the develop environment with a few apt-get commands.
When I started programming Qt, I lost a lot of hours to get a complete environment working with QtCreator, and I understand that not everybody has time for it.
I am using Qt Creator 3.5.1 based on Qt 5.5.1. The error "No compiler set in kit" has been a problem every time I have to configure a development system. The solution that worked for me is to select Tools/Options/Compilers and add a compiler. In my case a GCC compiler with Name:g++, Compiler path:/usr/bin/g++. The trick is to add the compiler before trying to add a Kit. If I add a Kit before I add a compiler I can never add the compiler to the Kit. If you having this problem delete the Kit, add a compiler, then add the Kit.
In your questions you must provide us more information about your problem, such as what versions of software are you using.
About your question, I think, that very good idea to you (as a beginner) is to use all-in-box QtSDK (link, need registration). There are ready-to-use QtCreator, MinGW and litle bit old Qt Libs in that QtSDK 1.2.1. So, you dont't need to configure it at all.
Hope, it'll help. Good luck!
I've installed Qt SDK 5.0.0 beta 2 and Qt Creator 2.6.0. It detects the package but gives a warning that "No qmlviewer installed". I've looked for it and it is in the SDK bin folder. What can I do? I use ubuntu 12.04 and I've added the SDK binaries to the PATH. I can view the QML files through the terminal.
It is not a solution but maybe it will be helpful.
I can see this warning too, but I think it is not a big problem. I have started to move my existing Quick1 code to new Qt version and I have not seen Qt5 Kit in the drop down list. But when I have created new Quick2 application I found it. And everything seems to work without QMLviewer.
Btw, I found forum post about Qt5 and qmlveiwer. Guy says that it was very difficult to support viewer in the actual state because API of declarative modules are changing very quickly. So they have dropped qmlviewer from Qt5.
I have downloaded QT SDK LGLP (Creator + libraries) 4.6 and I am having problems compiling projects. After install I have added C:\Qt\2010.02\qt;C:\Qt\2010.02\qt\bin to PATH and added QTDIR env varaible containing C:\Qt\2010.02\qt, the I run "configure -platform win32-g++" to compile it. Everything went good.
I the tried to use QT Creator to create and compile a project.
The problem is everytime I try to compile I get the following error message:
No valid Qt version set. Set one in Tools/Options
Error while building project GUITest
When executing build step 'QMake'
Canceled build.
When I go to Tools/Options the manual version is set to v4.6.2, Location c:\qt\2010.02\qt\bin\qmake.exe. The auto detected version is set to even though I have added the dirs in Path. Is there something I am doing wrong here? Has anyone encountered this problem in Vista.
I have been working on this for 2 days, change configurations, reinstalled etc...
The QtDir value is compiled into the
qmake-binary. You can only change this
by recompiling qmake and passing on a
different value to qt-configure (I'm
not sure which setting or variable is
passed on to qmake) When using
precompiled, downloaded binaries,
you'll have to keep the QtDir at
c:\Qt\4.6.2
EDIT:
What I said was incorrect. The locations of qmake, moc,... are located in the file:
<Qt>/4.x.x/.qmake.cache
Try uninstalling/reinstalling qt creator
But i highly suspect you didnt compile qt properly as this problem seems really odd. I had alot of problems compiling so i know myself from the past mistakes.
Make sure you carefully reread install instructions for your environment, also if you have visual studio you need to follow procedure to install it in compliance with it. Same if you use another c compiler
If nothing goes right, the easiest way to install qt imo is directy from their git hub, chec installin qt from git, on their git site there is wiki that explains how to do it
its really easy and after that all you need to do is add the qt to creator
Hey, it QT emulators have lot of problems in vista, i have tried several times,it didnt work for me.. it works well with windows XP. though ill tell you in brief what you need to do
1)install latest perl
2)install carbide c++ editor
3)install Qt SDK
4)install s60 or N97 emulators
make sure that except perl all the items which are mentioned above will be in same drive,and also
make sure that folder names which you give while installation should not have spaces at all..
i.e suppose if you are going to place any of the above items in a folder whose name is having spaces it will not work.
if you have any doubts feel free to ask.
