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.

Would it be possible for you to paste your wscript somewhere (like
gist.github.com) and share it here so that we can have a look and help
you with that?
