hi,dear Adam:
       thanks a lot for your time and effort!
       You are right! But is there any difference if  I build the binaries in one run or not?
I still have another problem that may have the same reason as this one:
       If I unpack the fiasco kernel first and build it, I can run the hello(many_thread,many_tasks...) example successfully.
But when I unpack the l4env and build again, the hello package can not pass the compilation processs. I can not find the reason.

can you give me some advice?

best wishes!
