erros in eclipse C++ by opening file from ros tutorial

edit

Hello to all,

when i open the add_two_ints_server.cpp from this tutorial with my C++ Eclipse Editor following failures are shown:

What file or dependency is eclipse missing? Or are that failures with multiple origins?

edit: I followed this IDE-Tutorial.

At step "1. Reusing your shell's environment", i build an new ros-package and copied the "c++ eclipse" files in it. Then I created a launch folder and file and pasted following:

<launch>
<node pkg="eclipse2" name="eclipse" type ="eclipse"/>
</launch>

By using the command "roslaunch eclipse2 eclipse.launch" I started C++ - Eclipse. (Eclipse starts with some warnings of missing log-files)

But these failures are still there.

Also I follwed the other steps of the tutorial.

Any Suggestions?

Many Thanks in advance Dominik
