Re: [Samba] how to reduce binary size of SAMBA 4 for embeded device




Hi, Bartlett

I decided to cut some subsystem by myself,
So I spent several days to study the SAMBA 4 WAF build system and now know the base steps of build.
but which subsystem can be removed for snmd/nmbd/smbpasswd ?

followings are the full dependencies of these 3 binary
