[Solved]Link error

pmjz

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

@main.o: In function neoseis::BusinessObject::setCurrentUser(QString const&)': /home/administrator/QtProjects/Source/Trunk/CrossSection-build-desktop/../../Trunk/AppLibrary/models/BusinessObject.h:59: undefined reference toneoseis::BusinessObject::m_currentUser'
CrossSectionPresenter.o: In function CrossSectionPresenter': /home/administrator/QtProjects/Source/Trunk/CrossSection-build-desktop/../CrossSection/CrossSectionPresenter.cpp:101: undefined reference toneoseis::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

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
}@
