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] :)
