I am using Windows 10 and I just want to change a little function on Qt designer 5.15.2 , is there a simple method to recompile the designer exe without much complications
I downloaded the sources and tried using cmake directly without success ,
Then I installed qt 6.2.2 and tried compiling designer.pro but got many errors
Any idea how to it faster ?

I am trying to cross compile a Qt4 application on Linux for Windows. I need to create an .exe (32 bit) from a Qt project, and I'm compiling under Linux (32 bit). Note that I'm not using Qt Creator, I am compiling with qmake.
I tried following many other tutorials/answers but I can't seem to make it work. Some suggest that I need MinGW but I can't find it for my platform (PCLinuxOS). Does anyone know where I can get it? Is there any other solution (apart from using Wine/Windows)?
I already have a copy of the headers and DLLs from Qt4 for Windows.
MXE does exactly what you want. It cross compiles to Windows. It comes with Qt, as well as many other libraries.
It's much easier to use than setting up a MinGW compiler on your own. You can start building in a matter of minutes, rather than spend the whole day setting up a cross compiler manually.
I have 2 different projects build with MinGW 4.7.2 using CMake and I need to link these to a Qt graphical app. Qt version is 4.7.4. OS is Windows 8 64bits.
The problem is that when I try to compile I get a huge amount of undefined references. After some research, I think it's because my version of Qt use minGW 4.4. Is that correct ?
Is there any way I could make the app work with my current configuration ?
If not, is there a different version of Qt that could work ? From what I saw the only option is to compile Qt with minGW 4.7.2. I tried and got errors when building it so if there's an easier way to make things work it would be great.
I also tried to compile my 2 projects with MinGW 4.4 but it crashs when i execute them so I have to keep MinGW 4.7.2 since I don't plan on doing more modifications to these 2 projects.
Also, as of now I use the mingw from mingw.org on a 64 bits laptop. I haven't got any problem because of that since now but maybe i should change to one of the mingw64 alternative ?
I am having trouble with compiling a Qt project using the MSVC 2012 compiler. I downloaded Qt first, then realised I didn't have a proper compiler yet, and then downloaded Microsoft Visual Studio Express 2012 and its msvc compilers.
However, whenever I try to compile something in Qt Creator, it gives the following error:
qtmain.lib(qtmain_win.obj):-1: LNK2038: mismatch detected for '_MSC_VER': value '1600' doesn't match with value '1700' in glwidget.obj
So my understanding of what this means is that my Qt libraries are of a different (older) version than my msvc compiler. But I am not sure how to fix it, or how to get other/newer libraries. Some googling told me that the following code added to the Qt .pro file should solve things:
QMAKE_COMPILER_DEFINES += _MSC_VER=1700 WIN32
But that didn't have any effect. Also, using '1600' instead of '1700' didn't help. Any ideas on what will?
I am working on a 32-bit Windows 7 system, if that's any help, and I'm using Qt 5.0.0.
You need binaries compiled for the Visual Studio 2012. Since there is no official (or unofficial) precompiled binaries available, you need to compile them by yourself.
This should not be complicated process, but it can be hard and frustrating for beginners to do to it, so I would suggest you to follow already given advice and to download VS2010 (afterall, it will take less time to download and install it than to compile Qt from source).
You have to use MSVC 2010, because the libraries are built using it. Try Visual C++ 2010 Express.
My goal is to be working on / debugging qt creator plugins and, maybe, editing / debugging qt creator source code. Towards this end I've tried a couple of things:
Downloading source for the qt sdk and qt creator, compiling each, and then making a qt creator plugin project and hooking everything together by hand. This got complicated pretty quickly (I tried to keep my plugin project outside the qt-creator/src/plugin/ folder) and doesn't really get me to a nice spot in terms of debugging.
Using an installed version of the qt creator to open the qtcreator.pro that came along with the source, adding a qt creator plugin as a sub project, and building everything from the already installed version of qt creator.
I like the second approach a lot because I have control over everything but I can rely on qt creators tools that make projects, enhance debugging, etc. There's just one small problem...
When I run my shiny new build of qt creator (with my plugin project) from inside the installed version all I get is a popup called "qtcreator_process_stub" that says "This is an internal helper of Qt Creator. Do not run it manually. Press to close this window..."
So I'm not really sure how to debug my build of qt creator from my instance of qt creator. Any ideas? Note: if I run the generated Qt Creator.app I get a functioning instance of qt creator with my plugin loaded properly.
I believe this was a versioning problem. I had an older version of the ide installed and was using it to build and debug a newer version of the ide.
I was able, in the older ide, to launch and debug the new ide as an external process through the debug menu... but that was mildly annoying.
Once I installed a new version of the ide I was able to debug like normal.
Questions:
Is Qt Creator built with Qt Creator?
Similarly, is Qt Designer built with Qt Designer?
BTW, why are there two Qt IDEs? Are they competitors? Which one should I use? I am using Creator.
What is Qt SDK? I am asking this because the Qt Designer & Creator 2.2.1 and Qtmake 4.7.4 that I installed thro ubuntu 11.10 s/w centre does not work. The build menu is all greyed out.
When I downloaded the latest QtSDK (2.3.1/4.7.4) into a separate installation into /opt/QtSDK, both the ubuntu sanctioned installation and the /opt/QtSDK would work as expected.
Why did my ubuntu sanctioned installation not work without the SDK? What does the SDK do?
This one is for Ubuntu enthusiasts - Qt IDE requires the SDK to work, and yet ubuntu released both Creator/Designer without checking if they work first? There is no QtSDK installation item in s/w centre. Is that intentional, or a procedural bug?
After I build my desktop app (I am building a tabbed file explorer) on Linux, what steps do I need to make to have it running on Windows 7/Vista? Will I rebuild on a windows version of Qt Creator?
I also notice that Qt Creator code generation is not perfect. It would forget to include some Qt library files in the auto-generated code, and I had to correct that manually.
Is Qt Creator built with Qt Creator?
I believe so.
That doesn't mean that everyone who works on Qt has to use it - just that I believe that lots of people do.
I don't work for any of the companies that have produced Qt, but my reasoning is:
A Google search for "dogfooding qt creator" brings up plenty of hits, including this comment from November 2010:
We’re also “dogfooding” by releasing complex apps like Qt Creator and the Ovi Suite on the desktop ports of Qt
They've put a massive amount of effort into Qt Creator over the last few years. It's hard to imagine that being worthwhile, unless they used it themselves
At recent Qt Developer Days, Qt Developers have spoken really enthusiastically about Qt Creator
Similarly, is Qt Designer built with Qt Designer?
Yes. A look at the Qt Designer source code shows plenty of .ui (Designer) files.
Why are there two Qt IDEs? Are they competitors? Which one should I use? I am using Creator.
When you edit .ui files insiide Qt Creator, you are still running Qt Designer: it's simply showing the Designer window inside Creator, for convenience.
What is Qt SDK? ... What does the SDK do?
Qt SDK is just a convenient way to download all the Qt tools in one go. You don't have to use it.
This one is for Ubuntu enthusiasts ... Is that intentional, or a procedural bug?
Sorry - no idea. It's hard to imagine it being intentional though.
After I build my desktop app (I am building a tabbed file explorer) on Linux, what steps do I need to make to have it running on Windows 7/Vista? Will I rebuild on a windows version of Qt Creator?
You will need to install Qt on a Windows PC, and then build your source code in it.
You can either do that by using Qt Creator and the Windows compiler it includes (mingw) or you can use another compiler, if you have one, e.g. Visual Studio.
I also notice that Qt Creator code generation is not perfect. It would forget to include some Qt library files in the auto-generated code, and I had to correct that manually.
If you've used any non-Qt classes in arguments to signals and slots, then this answer may help you there.
