It takes the relative address to the directory where the header file
is. For example, if you're building from the
"/home/olga/development/rtems" directory the includes argument would
be:

`includes = './rtems-5/testsuites/support/include/'`

BTW, your first email at the start of the thread says that you just
want to run the samples, the samples get built as a part of the rtems
and you'll be able to see the *.exe files in the build directory. Is
there any reason that you're trying to build it in a separate
directory with waf? Experimenting with the build system is a good
reason though, just making sure that we're not pushing you in the
wrong direction and your objective is indeed to try waf on your own
and not just running RTEMS hello app.

Best regards,
Vijay

In the wscript file from the "hello" example there is no "include" parameter. I also tried to find a tutorial on how to write a wscript, but didn't find any (Could you suggest any please?). So I tried to copy the file "tmacros.h" from testsuites/support/include to app/ticker. Now after running ./waf I get an error, which tells me that "buffer_test_io.h" wasn't found. When I copied it to my app/ticker directory it didn't work and I still have the same error.
