QTableWidgetItem text() function not linking ?

[marcvanriet]

Hi Lykurg,

Linking fails both in debug and release mode. I have built Qt statically both for release and debug mode.

QtCreator makes my .pro file, and Qt core and gui are included. I just added stuff to use QextSerialPort (which is working by the way, so that's not the issue). I would be surprised if I had to manually add an extra LIB just to use a QTableWidget.

QT       += core gui
TARGET = DibScan
TEMPLATE = app
SOURCES += main.cpp\
        mainDialog.cpp
HEADERS  += mainDialog.h
FORMS    += mainDialog.ui
INCLUDEPATH += ".\include"
LIBS          += -lqextserialport
win32:DEFINES  = _TTY_WIN_ QWT_DLL QT_DLL

QT       += core gui
TARGET = DibScan
TEMPLATE = app
SOURCES += main.cpp\
        mainDialog.cpp
HEADERS  += mainDialog.h
FORMS    += mainDialog.ui
INCLUDEPATH += ".\include"
LIBS          += -lqextserialport
win32:DEFINES  = _TTY_WIN_ QWT_DLL QT_DLL

To copy to clipboard, switch view to plain text mode 

I don't see why the QTableWidgetItem::setText() function is no problem, but the text() function is. It should be in the same source file in Qt I would think.

Best regards,
Marc

Can't see "CONFIG += static" and I don't know QT_DLL exactly, but dll is not what you want when you link static. I am a little confused. ([WIKI]Building static Qt on Windows[/WIKI])

Hi Lykurg,

Thanks, you pointed me in the right direction.

I just blindly copied the #win32EFINES = _TTY_WIN_ QWT_DLL QT_DLL from the example with QextSerialport to my .pro file. I tought it just had to do something with Qextserialport.

But the QT_DLL and QWT_DLL defines are of course not allowed for a static application. Everything works if I leave it out.

I'm not sure why I don't need the CONFIG += static line. I think it is because I modified the QMAKE_CFLAGS / CXXFLAGS / LFLAGS directly in the qmake.conf file in the mkspecs directory.

Best regards,
Marc
