I've set the includepath to QtCore in pro file but that doesn't work and includes still give error

[carlos91moreira]

Hello all,

After some days of this first experience with Qt I'm still facing lots of errors because of all the includes that I have.
I have this project and I need it to compile in Windows. I understand that I need to point the paths to the files needed in the .pro file.
But now I'm stuck in a circle.

In the INCLUDEPATH I have:

INCLUDEPATH += . \
               rcsc/formation \
               rcsc/geom \
               rcsc \
               rcsc/time \
               rcsc/param \
               rcsc/common \
               rcsc/rcg \
               $(BOOST_ROOT) \
               "C:/Qt/5.4/mingw491_32/include/QtCore" \
               "C:/tese/boost_1_58_0/boost"

With this I get an error in this line: #include <boost/weak_ptr.hpp>. But I have the path to that file (is the last line).
If I remove the last lines (please notice the 3 # sign):

INCLUDEPATH += . \
               rcsc/formation \
               rcsc/geom \
               rcsc \
               rcsc/time \
               rcsc/param \
               rcsc/common \
               rcsc/rcg \
               $(BOOST_ROOT) **#**\
               **#**"C:/tese/boost_1_58_0/boost" \
               **#**"C:/Qt/5.4/mingw491_32/include/QtCore"

The error I get is in line: #include <QtCore/qpair.h> (no such file or directory found)

This error lead me to include the line "C:/Qt/5.4/mingw491_32/include/QtCore" to the INCLUDEPATH and I go back to the top of this problem.

I've this in .pro file as well:

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
greaterThan(QT_MAJOR_VERSION, 4): QT += core
greaterThan(QT_MAJOR_VERSION, 4): QT += gui

This is my .pro file:

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
greaterThan(QT_MAJOR_VERSION, 4): QT += core
greaterThan(QT_MAJOR_VERSION, 4): QT += gui


TARGET = matchflow

TEMPLATE = app
DEPENDPATH += rcsc \
              rcsc/common \
              rcsc/formation \
              rcsc/geom \
              rcsc/param \
              rcsc/rcg \
              rcsc/time
INCLUDEPATH += . \
               rcsc/formation \
               rcsc/geom \
               rcsc \
               rcsc/time \
               rcsc/param \
               rcsc/common \
               rcsc/rcg \
               $(BOOST_ROOT) #\
               #"C:/tese/boost_1_58_0/boost" \
               #"C:/Qt/5.4/mingw491_32/include/QtCore"


LIBS += -lstdc++

And the rest are Headers and Sources.

If anyone ever had the same problem please help me.
Many Thanks :)

Hi,

You should rather be including QPair.

Note that you only need greaterThan(QT_MAJOR_VERSION, 4): QT += widgets for the widgets part because they have moved in their own module in Qt 5

Hi,

thanks very much once again.

That worked perfectly :D

How can I set this as closed (or solved)?

[SGaist]

Easy: just edit the thread title and prepend [solved] :)
