At line line 42(-d option) I enable debug but sshd.log is empty.
At first run sshd_start.app creates keys and exits:

Every next run print just nothing:

/mnt/ext1/applications $ sshd_start.app
/mnt/ext1/applications $

When I execute sshd_stop this is the result:

sshd_stop.app
killall: sshd: no process killed

Yes I'm new to cross-compiling packages from source code
I have some experience only in traditional compiling under linux ( for example ./configure; make; sudo make install)

I agree with you it's far better to find way to run without compiling
