Compiling error qt 5.2.0 os x mavericks

LORDIF

Getting this error:

/Users/eugenekolesnikov/Qt5.2.0/5.2.0/clang_64/lib/QtWidgets.framework/Headers/qsizepolicy.h:52: error: variable has incomplete type 'class Q_WIDGETS_EXPORT'
class Q_WIDGETS_EXPORT QSizePolicy
^

How to solve that problem?

LORDIF

Solved that problem by changing the path of "include" directory.
But arises another problem:

:-1: error: symbol(s) not found for architecture x86_64

QMAKE_MACOSX_DEPLOYMENT_TARGET=10.9 doesn't help....

Hi and welcome to devnet,

How did you installed Qt ?

What does your pro file look like ?

LORDIF

installed via macports

.pro file:
@
QT += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = TestProj
TEMPLATE = app

CONFIG += MAC_CONFIG

MAC_CONFIG {
QMAKE_CXXFLAGS = -mmacosx-version-min=10.9
QMAKE_LFLAGS = -mmacosx-version-min=10.9
}

INCLUDEPATH += /Users/eugenekolesnikov/Library/OpencvLib
/usr/local/include
LIBS +=
-L/opt/local/lib
-lopencv_core
-lopencv_imgproc
-lopencv_highgui
-lopencv_objdetect
-lm

SOURCES += main.cpp
mainwindow.cpp

HEADERS += mainwindow.h

FORMS += mainwindow.ui
@

[edit: added missing coding tags @ SGaist]

Unless you have macports in a strange place, your error says that it's searching in /Users/eugenekolesnikov/Qt5.2.0/5.2.0/clang_64/lib/

So it seems you have something mixed-up . Did you install Qt through the installer once ?

LORDIF

Yes, sorry... my mistake... used macports to install qt4, this one i installed manually or kind of... can't compile from source code, because have this error "clang: error: unsupported option '-static-libgcc'"

SGaist

How did you "kind of manually" installed it ?

LORDIF

I've downloaded dmg file and executed it

LORDIF

I think that the problem with opencv lib

Compiling from the console I got more words about the error so now it can be analysed:

Undefined symbols for architecture x86_64:
"NeuralNet::~NeuralNet()", referenced from:
MainWindow::MainWindow(QWidget*) in mainwindow.o
MainWindow::~MainWindow() in mainwindow.o
MainWindow::~MainWindow() in mainwindow.o
non-virtual thunk to MainWindow::~MainWindow() in mainwindow.o

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [TestGuiProj.app/Contents/MacOS/TestGuiProj] Error 1

LORDIF

Finally got this error and I don't know what does that mean

Undefined symbols for architecture x86_64:
"NeuralNet::~NeuralNet()", referenced from:
MainWindow::MainWindow(QWidget*) in mainwindow.o
MainWindow::~MainWindow() in mainwindow.o
ld: symbol(s) not found for architecture x86_64

SGaist

What is NeuralNet ?

The error means that it can't find the implementation of the destructor of NerualNet for 64 bit
