Compilation problem:/RemoteWeb/SoftwareDevelop/SBlogProject/SBlog/ArticleListWidget.cpp:85: error: undefined reference to `Wt::Dbo::Query<Wt::Dbo::ptr<SbDbItem>, Wt::Dbo::DynamicBinding>::operator Wt::Dbo::collection<Wt::Dbo::ptr<SbDbItem> >() const'

I'm developing a blog system.

While compiling my code , I got this error: /RemoteWeb/SoftwareDevelop/SBlogProject/SBlog/ArticleListWidget.cpp:85: error: undefined reference to `Wt::Dbo::Query<Wt::Dbo::ptr, Wt::Dbo::DynamicBinding>::operator Wt::Dbo::collection<Wt::Dbo::ptr >() const'.

It seemed that I have misused templates . However , I couldn't find where the error is .

Please take a look at my code and tell me what's the problem.

My code is devided into two projects:sbdatabaseaccess and sblog.

SbDatabaseAccess.zip is a library project , I placed the database accessing code into it . Your have to compile and install the project first like this: qmake-qt4;make ;make install

SBlog.zip is the actual blog system which links to libsbdatabaseaccess.so . Again, you compile it like this: qmake-qt4;make . But I got the error in the title while compiling this project.

I uploaded the code of these two projects . Please let me know if you need any further information.

Hey,

I did not take a look at the source code, but I can only explain this if you are including instead of ?
