Why need ../ to include the path in Qt5?

[mameo]

Hi,

I transplanted the source that was made with Qt4 to Qt5.
Inclusion of compilation errors had out a lot.

When an attempt is made to include the file in a different folder,
You do not specify the ../ and it becomes a compile error.
It was no problem in Qt4.
Do I need something set?

<Folder structure>

• sample
  main.cpp
  • Model
    SampleModel.h, SampleModel.cpp
  • Data
    SampleData.h, SampleData.cpp

<Qt4 source code of>
/ * SampleModel.h * /
#include "Data / SampleData.h"

<Qt5 source code of>
#include "Data / SampleData.h" // error
#include "../Data/SampleData.h"

Use environment: Windows7 64bit, QtCreator 3.3.0, Qt5.4.0

Best regards,

The paths depend on what you put in INCLUDEPATH variable in .pro file.

I'm sorry. I do not know what to do with.

I tried to add a INCLUDEPATH, but you get an error.
Error content is below.
C1083: 'Data / SampleData.h' No such file or directory.

#Sample.pro
QT += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = Sample
TEMPLATE = app

INCLUDEPATH +=
Data \

SOURCES += main.cpp
Data/SampleData.cpp
Model/SampleModel.cpp

HEADERS +=
Data/SampleData.h
Model/SampleModel.h

FORMS += \

Thank you.

Try
@
#include "SampleData.h"
@

There was no change here between Qt 4 and 5, so it really should work.

I solved the problem.
It was resolved by adding a $$ PWD to include path.

QT += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = Sample
TEMPLATE = app

INCLUDEPATH += $$PWD

SOURCES += main.cpp
Data/SampleData.cpp
Model/SampleModel.cpp

HEADERS += Data/SampleData.h
Model/SampleModel.h

Mr. sierdzio.
Thank you tell me.

Hm, that is unusual, but good that you've found this out. Happy coding!
