Yes. It finished without warning or errors. Thanks.

Now, building the sample application. I have done what says in the link:
http://www.rtems.org/onlinedocs/releases/rtemsdocs-4.10.2/share/rtems/html/started/started00063.html

But is not working. It is accusing that there is no makefile or leaf.cfg
file in the specified directory.
Do I have to set any variable other then RTEMS_MAKEFILE_PATH?
What about in which directory to put the sample source folder, let's say, *
hello_world_c* folder?

Alright. I'm going to download the latest VM available.
