Note : You have eventually to change "port=8100" into "port=2083" for recent SDK (after 2.X).

-Remember each time you query for an interface you have to add code lines (if they don't exist) in the source code and a line in the makefile. I will generally add comments to prevent omissions. You can find more explanations [[IDL_Files_and_Cpp#IDL__and_C.2B.2B|here]] (if you are not a beginner).

-{{Documentation/Note|'''Important Note''' : The more important point in the compilation chain of the examples below is that <code>cppumaker</code> will construct every hpp and hdl files you need in your application.
