@mrjj

there is a something weird !! when i run with release mode it works but not with debug mode

[aha_1980]

@krichen30 You may also get this error if you're mixing debug and release libraries on Windows.

[krichen30]

@aha_1980 how can i fix it ?

[aha_1980]

@krichen30 At first I would try a clean rebuild.

[mrjj]

Hi
it doesn't look like you have any global widgets just a normal mainwindow.
So yeah, try as @aha_1980 suggest and completely wipe the
build folder.

[krichen30]

i delete the folder debug and i redebug it but nothing change same error ...

@krichen30
Hi
You only have the Satistique class ?
and no other files?

Does it say this when running from creator ?

[krichen30]

@mrjj i have another files but not include in this statistique class

[krichen30]

do you have solution please !!!

[mrjj]

@krichen30
Nope. If you dont have any global QWidgets/QObject before main is run, i
have no idea.

Perhaps a QSqlDatabase? If there's a static instance, it will also cause this error.

[mrjj]

@hskoglund
Very good guess since he as SQL classes.

[krichen30]

@hskoglund what is the relation between QSqlDatabase and QWidget ?

[mrjj]

@krichen30
But do you have a static QSqlDatabase ?
