Compiling without rtems-libbsd

Actually I'm able to compile with waf, I just had to create another 
file in Testsuites and added it to the script in the 
rtems-libbsd folder. Thanks Chris for the help.

But I prefer to develop in eclipse. With RTEMS(without bsd) I could do 
it because the programs are imported from a Makefile, the new question 

Is it possible to compile without using waf and without calling the 
rtems-libbbsd repository ("supposedly" I already have the necessary 
files in rtems-4.12 when the command “waf install” copied them) using 
only the rtems-4.12 folder that is generated after all installation 

Thanks in advance.

By the way, I haven't a file named "". Rtems_waf folder 
contains the sources, and
