Description
Hello,
i'm trying to get the tutorial9 to work under wt4. But that doesn't work. Does anyone have an example with Dbo under Wt4?

Can you outline the steps you're using to compile it? If you are doing it properly, it should find <Wt/Dbo/Dbo.h>.

So you are using cmake on only that CMakeLists.txt that's in the tutorial9 directory? That's not a standalone CMakeLists.txt. Only the CMakeLists.txt in the root directory of the Wt source tree, and the CMakeLists.txt in the examples directory can be used standalone.

Thanks for the Information but now I have a link problem:
"vtable for Wt::Dbo::MetaDboBase", referenced from:
Wt::Dbo::MetaDboBase::MetaDboBase(int, int, Wt::Dbo::Session*) in mainDbo.C.o
NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.
"vtable for Wt::Dbo::Impl::ParameterBase", referenced from:
Wt::Dbo::Impl::ParameterBase::ParameterBase() in mainDbo.C.o
NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.
"vtable for Wt::Dbo::ptr_base", referenced from:
Wt::Dbo::ptr_base::ptr_base() in mainDbo.C.o
NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.

It seems you use Clion IDE.
I'm using Dbo from Wt-4.0.5 with not linking issues on Linux.
Assuming you have an expected Witty installation:
myApp main
#include <Wt/Dbo/Exception.h>
#include <Wt/Dbo/backend/Postgres.h> // PostgreSQL backend
int main()
{
try
{
some_dbo_function();
}catch(const Wt::Dbo::Exception &x){
std::cerr << "Dbo exception " << x.what() << std::endl;
}
CMakeLists.txt
cmake_minimum_required(VERSION 3.7)
project(myapp)
set(CMAKE_CXX_STANDARD 14)
set(SOURCE_FILES myapp.cxx )
link_directories(/usr/local/lib)
add_executable(myapp ${SOURCE_FILES})
target_link_libraries(myapp wt wtdbo wtdbopostgres)
