Hi Franc,

thank you for trying out Genode!

when started, init tries to obtain the binary of the dynamic linker as a
ROM session. In the simple printf scenario, however, no dynamically
linked binaries are used. So the dynamic linker is not present in the
boot image. The easiest way to silence the message would be to add the
dynamic linker (ld.lib.so) to the boot image by adding the file name to
the 'build_boot_image' step in the run script.

However, because your scenario does not rely on it, the dynamic linker
is not built automatically. So you'd need to build at least one target
that depends on a shared library. For example, 'test/ldso'.

Btw, for questions like your's, let me recommend you to post on our
mailing list. This way, you may get assistance from more people than
just me. Also the discussion might be helpful for other people who might
stumble over the same problem in the future.

Cheers
Norman
