QPrinter problem QT 5.9.2 and 5.8

@Krasnoiark
That sounds pretty ok.

Can you try this default project and tell if it also gives errors?

Also, you are targeting Desktop, correct ?
Its not bare metal project or something like that?

@Krasnoiark Most probably not the reason for the problem, but why do you add core and gui twice to QT?

[Krasnoiark]

It compiles and there is no errors

[mrjj]

@Krasnoiark
So i think your .pro or kit selection might be messed up.

This is a desktop app, correct?

[Krasnoiark]

Yes, this is a Desktop project and the project is a QTWidget project insite 2 other QT Sub-projects.

[mrjj]

Hmm
It does look fine with the kit.

It must be something with the pro file then

Since the test project worked and I assume you compiled that
exactly like this.

This is my .pro file

@mrjj I believe that once in the past you told me to try deleting the build folder. It has solved many of my problems, is it worth a try?

[jsulm]

@Krasnoiark You still add gui twice.
Do you have other Qt installations on your machine?

[mrjj]

@ofmrew
its always worth a try :) Especially when stuff are strange. Good call.

[Krasnoiark]

@ofmrew No I don't. All I have is QT 5.9.2 MinGW and the tools
.

I have tryed recompiling from scratch, it did not work.

[mrjj]

It seems not to be the pro file as
it is pretty basic and it could compile my project too.

And QPrinter is included in the installation as a default project works.

My best bet is that the
$$files(.cpp)
$$files(classes/.cpp)
$$files(gui/*.cpp) \

find something we dont expect and include.

[Krasnoiark]

@mrjj I have tryed retyping all the pro file with all the files included but no luck.
Do you think it could be about the multiple projects ? I have my software project inside a sub-project inside an other sub-project. (My team needed multiple projects in order to have the testing project and the software and a 2nd project because our project has multiple softwares ).
In the sub project I only include the projects it gathers. Should I include qprintsupport inside that pro file ?

[mrjj]

If the sub projects also have .pro file
and you get the linker error in them/related to those files
then yes, you need
QT+=printsupport there also to link the module to that set of .o files.

[Krasnoiark]

OK THAT WAS IT ! I had to include inside the pro files the QT += printsupport.
Thank you for helping me and sorry for taking your time. It was pretty stupid of me not to check that.
Anyway, thank you.

@Krasnoiark
No problem at all.
I also learn something :)

I had no idea you could do

$$files(*.cpp) 

thx :)
