Mingw32 undefined reference

[Dre4m]

Hello,
Im pretty new to Qt and i have encountered problem. I've made my project using MinGW 64-bit and recently it looks like i will aim for 32-bit platform so i tried to build my project using 32-bit MinGW, instaled with maintanance tool, but it turned out to be not working at all . It throws a lot of undefined refernce errors , i mean a lot of them , so i tried to run a simple example(from qt creator inside examples) using this configuration and it throws same "package" of errors.Any idea what i might did wrong ?Made ss of my configuration and errors and put in links below

Kind regard
Simon

@Dre4m
Did you edit the target path ?
Also can you create a small sample and try?

[Dre4m]

Can you try ?

[Dre4m]

@Ratzz
I would love to but i dont understand what sample should i make or how to be specific.

[Ratzz]

@Dre4m
Just make an empty project and run it.
File->newproject->Application->Qt Widget Application

and its perfectly working while using MinGW 64-bit, is it possible that during installation of mingw 32 something went wrong, or i dont know linker is using mingw64 or something like that ?

@Dre4m
How did you install Qt? And what version and configuration did you select?

@Dre4m said in Mingw32 undefined reference:

instaled with maintanance tool,

And what does this mean?

[Dre4m]

just like that

[Ratzz]

@Dre4m
Can you show kits configuration for MinGW 32 bit and MinGW 64 bit.
also Qt has MinGW 32 bit .

[Dre4m]

for mingw 32

for mingw 64

[Dre4m]

any idea?

[jsulm]

@Dre4m What I can see is that your 32bit compiler is 5.3.0 and the 64bit one is 7.3.0
Can you try to install 32bit 7.3.0 compiler?

[Dre4m]

For this setting of MinGW32 bit :

i get those error while trying to build :

any idea what can be wrong ?
64bit version is working perfectly.

@Dre4m Can you copy paste the error messages instead of posting a screen shot? And it should contain the first error.
Also please post your pro file.

@Dre4m One more note: when switching to another Kit (or modifying existing one) please delete build directory, run qmake and build.
