Undefined reference to library after static compiling qt

michael_endres · wrote on 20 Dec 2013, 10:17

Hey,
i compiled qt for windows static wothout any error and if i compile and execute a programm with qt creator without libs it is working. But if i want to use the Qt libs and include them, it says i.e QCoreApplication was not declared. After adding them in the*.pro file it says undefined reference to them.

*.pro file
#-------------------------------------------------

Project created by QtCreator 2013-12-20T10:42:53

#-------------------------------------------------

QT += core

QT -= gui

TARGET = untitled1
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app
LIBS += -LC:\qt-everywhere-opensource-src-5.2.0_14Versuch\qtbase\lib -lQt5Core
INCLUDEPATH += C:\qt-everywhere-opensource-src-5.2.0_14Versuch\qtbase\include\QtCore

SOURCES += main.cpp

main.cpp
#include <QCoreApplication>
using namespace std;
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);

return a.exec(&#41;;

}

Can anybody help me?

first you need to add the following line to your .pro file
@CONFIG += static@

And also note that you need to rerun qmake everytime you alter the .pro file.

Thx for your answer.

i added the CONFIG+=static in the project settings in additional arguments, but i can do it in the Pro file again.
I saw that the #include<QCoreApplication> refers to my standart qt under c: Qt5.2/...
how can i change this?

This is my error:

check your qt creator settings.
Or if you use the command prompt make sure your environment variables are pointing to correct qt installation.

michael_endres · wrote on 20 Dec 2013, 13:08

which settings can i check? the environment variables are ok and i get the same error in command prompt as in qt creator.

i noticed that the include< offers files depending on the projectpath, but there is no Q... as proposal

raven-worx · wrote on 20 Dec 2013, 13:11

QTDIR, etc.
just check all of them to make sure ;)

They seem to be ok. No path to the old(normal) qt-version.

Maybe i built qt wrong?
here is my command:
