run example applications

[domenico.dileo at unina.it]

Hello,
I want to compile the example applications available at:
http://www.rtems.org/wiki/index.php/Example_Application_Compiling

 From the instructions there,
we have to :
a) run make install in the rtems build directory
b) move to the example folder, create the variable RTMES_MAKEFILE_PATH
and invoke make

I suppose that the with a) we
define the environment variables PROJECT_ROOT and RTEMS_CUSTOM
needed in the Makefile of the examples

If I  don't want to run the make install in rtems build directory
and I want to directly assign a value to these variables,
what should I write?
PROJECT_ROOT= is the top folder of the rtems tree ( in which
there is the rtems code itself,  the testsuite and  so on)

RTEMS_CUSTOM = ?

Thank you in advance for your help

Domenico
