can't start smbd after install samba posix branch

[Xiaoli Feng <xifeng@redhat.com>]

Hello folks,

I try to install samba posix branch in RHEL8. But failed to start smbd daemon.
Does anyone know the reason? or what else do I miss?

#git clone git://git.samba.org/jra/samba
#git check -b posix remotes/origin/master-smb2
#./configure --prefix=/usr --enable-fhs
#make -j6
#make install
#smbd -D
# echo $?
1
# smbd -D -d 10

I don't find any usefull log. Then I use systemd to start smbd services. Show this error:
-- Unit smb.service has begun starting up.
