[Solved]Link error
Hi guys,
I build my project and finally whole batch of errors like below appeared, looks like linking has some problems, by the way, I run C++ project on ubuntu 64bit OS. and I installed 64bits OS on my 32Bit computer
welcome any idea
- /home/administrator/QtProjects/Source/Trunk/CrossSection-build-desktop/../../Trunk/AppLibrary/models/BusinessObject.h:59: undefined reference to `neoseis::BusinessObject::m_currentUser'
- CrossSectionPresenter.o: In function `CrossSectionPresenter':
- /home/administrator/QtProjects/Source/Trunk/CrossSection-build-desktop/../CrossSection/CrossSectionPresenter.cpp:101: undefined reference to `neoseis::ScrollViewPresenter::ScrollViewPresenter(QString const&, neoseis::View2D*)'
- /home/administrator/QtProjects/Source/Trunk/CrossSection-build-desktop/../CrossSection/CrossSectionPresenter.cpp:104: undefined reference to `neoseis::Presenter2D::view() const'

The information provided is not enough to help you.
But ins most cases you need to add to your .pro file:
In case of linking problem regarding one internal ( made by you ) function, you
must include the .ccp file ( BusinessObject and Presenter2D ).
In case of 3rd party library, you must include the .lib ( or .a ) in your .pro file
- QT += core gui opengl sql xml
- CONFIG +=console
- TARGET = CrossSection
- TEMPLATE = app
- win32:RC_FILE += CrossSection.rc
- SOURCES += main.cpp\
- CrossSectionPresenter.cpp \
- Bootstrapper.cpp \
- CrossSectionView.cpp
- HEADERS += \
- CrossSectionPresenter.h \
- CrossSectionView.h \
- INCLUDEPATH += ../ \
- ../AppLibrary/ \
- ../BusinessObjects/ \
- CONFIG(debug, debug|release){
- LIBS += \
- -L../AppLibrary-build-desktop/debug -lAppLibrary \
- -L../BusinessObjects-build-desktop/debug -lBusinessObjects
- }
- CONFIG(release, debug|release){
- LIBS += \
- -L../AppLibrary-build-desktop/release -lAppLibrary \
- -L../BusinessObjects-build-desktop/release -lBusinessObjects
- }
- RESOURCES += \
- AppResources.qrc \
- ../AppLibrary/Resources.qrc \
- ../Logging/LoggingResources.qrc
- OTHER_FILES += \
- qt.conf \
- CrossSection.rc
thanks a lot, the problem is fixed because of the wrong place where I put .o in. the solution is just to remove the subfolder of the debug and release
- CONFIG(debug, debug|release){
- LIBS += \
- -L../AppLibrary-build-desktop -lAppLibrary \
- -L../BusinessObjects-build-desktop -lBusinessObjects
- }
- CONFIG(release, debug|release){
- LIBS += \
- -L../AppLibrary-build-desktop -lAppLibrary \
- -L../BusinessObjects-build-desktop -lBusinessObjects
- }
