It is run via Visual Studio, which is quite simple. And now with RTEMS I am a bit frustrated and don't know where to start. That's why I followed the tutorial on the Website. "Hello World" program worked just fine, so I decided to try some more complicated applications before I start with my own, that's why I decided to build "ticker" with waf. Unfortunately I didn't find any helpful (for me) tutorial on how to create applications in RTEMS. I mean I can handle writing the App's code, but I don't get it how to compile and run it. So I was just going to do the same as in the tutorial, but with my own application.

It takes the relative address to the directory where the header file<br>
is. For example, if you're building from the<br>
"/home/olga/development/rtems" directory the includes argument would<br>
be:<br>
<br>
`includes = './rtems-5/testsuites/support/include/'`<br>
<br>
BTW, your first email at the start of the thread says that you just<br>
want to run the samples, the samples get built as a part of the rtems<br>
and you'll be able to see the *.exe files in the build directory. Is<br>
there any reason that you're trying to build it in a separate<br>
directory with waf? Experimenting with the build system is a good<br>
reason though, just making sure that we're not pushing you in the<br>
wrong direction and your objective is indeed to try waf on your own<br>
and not just running RTEMS hello app.<br>
<br>

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.<br>
