Run a working project on a new Computer

Hi @DavidM29,
It seems you installed way more Qt versions than needed. I'd recommend uninstalling the ones you don't wanne use to avoid confusion.
The selected MinGW kit looks good at first sight.
Which Qt version did you use before?
Have you completely removed all build artifacts and the .pro.user before opening the project?
I do have a main :
Yeah, but the error is:
crt0_c.c:-1: error : undefined reference to `WinMain@16
WinMain is the function that calls your main.
If the error still persists after carefully cleaning all build artifacts, can you show a build log for a full compile?
Regards
@aha_1980
I installed the complete package when I installed Qt so that is probably the reason why I do have as many kits.
How can I uninstall them ? Should I do it manually ? I never know which one should I used and if it is supposed to make any difference to be honest ...
EDIT : I found out with the Maintenance tool.I used Qt 5.10. on my previous computer, now it is 5.13 (latest version)
But why would it be looking for a WinMain ? I've never used WinMain before !
I do not have anymore build artifacts and .pro.user has been removed.
The complete Compile output :
(Sorry for the image format but don't know how to share it an other way... Too many character for a single post...)

you can upload such logs into paste services.
One strong advice: Don't use project directories with spaces or special charactes in it. That may be no problem here, but will sooner or later hit you somewhere else.
Regarding the problem: do you have a
libmingw32.a? The path to this file looks extremely long and odd.Can you compile a minimal example from the wizards?

Ok I clearly have some lacks...
What is "paste services" ?I'll change the name of the project then, that is true that special characters and spaces are usually source of problems.
What do you mean by "compile a minimal exemple" ? Create a new "Hello world" project and compile it for exemple ?

Ok thanks, I've never used this before...So, I've made a project named Test that is basicly a Qt Quick project made with the wizard.

@DavidM29 can you show the .pro file for the specific target (it seems you have multiple targets in a SUBDIRS project?)

Yes I do have a "main" .pro which is this one

Yes you are right...
It is my tests files.... Why does it try to run them ?Edit : Indeed I try to remove the "tests" sub from my project .pro file and no the app is running...
But my tests used to work as well before ... But it is very good to know what make this error.Edit 2 : I finally found my problem... I had a missing file in my test.pro ... Adding this missing file solve my problem.
I can keep my test and my app Launch properly !
Thanks a lot for you help ! -
