error: undefined reference to qInitResources_pbuffers()

[saman_artorious]

I receive below error when I add:

Q_INIT_RESOURCE(pbuffers);

Q_INIT_RESOURCE(pbuffers);

To copy to clipboard, switch view to plain text mode 

error: undefined reference to qInitResources_pbuffers()

Image is added to resource.qrc, I read a pre-posted thread about this, but it did not help. here's .pro file:

QT       += core gui opengl
 
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
 
TARGET = PixelBuffersExample
TEMPLATE = app
 
 
SOURCES += main.cpp\
        mainwindow.cpp \
    cube.cpp \
    glwidget.cpp
 
HEADERS  += mainwindow.h \
    cube.h \
    glwidget.h
 
FORMS    += mainwindow.ui
 
RESOURCES += \
resource.qrc
