@Christian-Ehrlicher Sorry, where can I find the info you requested me?

In the Kit settings

I am trying to build 32-bit application after successfully building the 64-bit.
Did the same project successfully built in 64-bit?
looks like uic compiler of Qt4 version is linked, clean and rebuild the project.
check whether generated "ui_mainwindow.h" file having current timestamp.
have a look into makefile and check whether it's reflecting the valid settings.

I came to realize that the 64-bit that built successfully is the Qt 6.0.0 mingw 64 bit and Qt 6.0.1 mingw 64 bit not Qt 5.15.2 mingw 64 bit as I don't have it installed.
clean and rebuild the project.
Did that multiple times, same result

Didn't understand, how do I do that?

How will I know if it not reflecting valid settings

This is Qt4. Are you sure you installed Qt4/32bit correctly? I would guess no.
Make sure the correct uic compiler is picked up (the Qt5 one) if you have installed and want to use Qt5@Christian-Ehrlicher said in Qt 5.15.2 MinGW 32-bit throwing errors but 64-bit version working fine.:

@hbatalha in the build directory check for Makefile. Debug/Release based on your build
and search for bin/uic and confirm it's from the currect version..@nagesh So I uinstalled Qt 5.15.2 MinGW 32-bit and installed Qt 5.15.1 MinGW 32-bit(just for the sake of trying), same results
search for bin/uic and confirm it's from the currect version..
C:/Qt/5.15.1/mingw81_32/bin/uic.exe
That is what I found, I guessing it is right version
-
As I already said - either there is a uic.exe from Qt4 around or you checked in the generated ui_mainwindow.h (which also then was created with a Qt4 uic) - remove both.

remove both.
To remove uic.exe and the generated ui_mainwindow.h???
Sorry I don't understand what exactly you are telling me to do.either there is a uic.exe from Qt4 around
I would guess no. Is there any possible scenario where you would download compilers only from qt5 and end up with some files from qt4 in them?
-
Remove the ui_mainwindow.h - it was created with an uic.exe from Qt4.

@Christian-Ehrlicher I did that and it solved the first error. But I am still left with the other 2 types of compiling error mentioned in the OP.

The documentation to QSpinBox::valueChanged() exectly desribes your problem. Reading docs is sometimes useful...

@Christian-Ehrlicher yeah it works, but still... when I compile using Qt 6.0.1 64-bit it works fine, it should work.
The problem is not really the compile errors, it is why my code works fine using Qt 6.0.1 64-bit and fails when using Qt 5.15.1/2 32-bit.
In the OP I posted 3 errors but it is really 3 type of errors, there are a lot more than just 3 errors all over my project and also there are other type of errors.
I tried commenting the lines that threw the errors and it compiled successfully and thus a question arose: will I have to rewrite everything so it can compile in 32-bit?? That doesn't seem right to me, I don't think it is supposed to be this way.
-
Because the overloads triggering the compilation error have been either renamed or removed in Qt 6.

@SGaist Since Qt 6 doesn't yet support 32-bit I should rewrite my code to get it to compile in 32-bit? It will feel like walking backwards though but if that's all to it I don't think I have much of a choice if I want to get my program in 32-bit exe.

You have to compile Qt6 for 32bit and then compile your app using that Qt build.

@hbatalha said in Qt 5.15.2 MinGW 32-bit throwing errors but 64-bit version working fine.:

No, you don't.
You just need to modify your
connect()statements, following the documentation that @Christian-Ehrlicher linked you: https://doc.qt.io/qt-5/qspinbox.html#valueChangedWhen your code fully compiles in Qt 5, it will also compile in Qt 6. It will work for 32-bit AND 64-bit.
...so it can compile in 32-bit??
Please understand: This is not a difference between 32-bit and 64-bit. This is a difference between Qt 5 and Qt 6.
Your current code will have the same errors with Qt 5 64-bit.

Yeah I know, when I said "rewrite everything" I meant only the code that is triggering compiler errors. I think I misspoke.
When your code fully compiles in Qt 5, it will also compile in Qt 6. It will work for 32-bit AND 64-bit.
Please understand: This is not a difference between 32-bit and 64-bit. This is a difference between Qt 5 and Qt 6.
Your current code will have the same errors with Qt 5 64-bit.I am aware of all that, it just feels like walking backwards that's all. Hope the support for 32-bit in Qt 6 starts soon.
