RTEMS 5 how to run "hello" example

Tue Mar 16 10:07:43 UTC 2021

Thank you very much for your reply!

I've added
includes =
'/home/olga/development/rtems/rtems-5/testsuites/support/include/tmacros.h',

it still says "No such file or directory". I'm pretty sure the path is
write, though there is now another path to "tmacros.h" (the first one
below), it's a folder named "tmacros.h" and it's empty.
olga at olga-H270M-DS3H:~$ locate tmacros.h
/home/olga/development/app/ticker/build/sparc-rtems5-erc32/$HOME/developement/rtems/rtems-5/testsuites/support/include/tmacros.h
/home/olga/development/rtems/rtems-5/testsuites/support/include/tmacros.h
