This will only fix the warnings, but won't fix the build.

The real error is that the linker cannot find a library:

Do you have such library? Why have you told the linker to search for it there?

You're supposed to pass only one -std option. Passing both doesn't make too much difference only might confuse someone.

djadrian:
Ok sorry, I am using now only -std=c++11.
The library was there (/opt/vc/lib/) but after rebooting the file just disappeared, I have no idea what happened and how to fix it now.

Before it the code compiled but libvmcs_rpc_client.a library was missing (black picture from the first post)

Any idea what to do now?
