Thanks. In this line: https://github.com/syrba4eva/RTEMS/blob/main/wscript#L33
After cflags parameter, add "includes", for example:

bld(features = 'c cprogram',
      target = 'ticker.exe',
      cflags = '-g -O2',
      includes='. .. ./original/path/to/tmacros.h',
      source = ['init.c', 'tasks.c'])

you don't need to copy tmacros.h or any headers from rtems, just add
the path to includes.


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.
