Cross Compiling Samba
Download the source and uncompress:

https://ftp.samba.org/pub/samba/

wget http://samba.org/samba/ftp/stable/samba-3.6.23.tar.gz
tar -xzf samba-3.6.23.tar.gz

And cross compile for ARM:

cd samba-3.6.23/source3
./autogen.sh
./configure --without-krb5 --without-ldap --without-ads \
  --disable-cups --enable-swat=no --with-winbind=no \
  --target=arm-linux-gnueabi --host=arm-linux-gnueabi \
  --prefix= --with-configdir=/etc \
  samba_cv_CC_NEGATIVE_ENUM_VALUES=yes \    
  libreplace_cv_HAVE_GETADDRINFO=no \
  ac_cv_file__proc_sys_kernel_core_pattern=yes
make
make install DESTDIR=/home/export/rootfs

Creating smb.conf
Create a Samba configuration file (smb.conf) and place it in /etc. Below is a minimal example configuration, sharing the home directories located in /home.

[global]
workgroup = WORKGROUP
netbios name = SAMBA_FS
[Home]
path = /home
writable = yes
comment = Home Directories

Starting Samba
Samba can be started using the following. smbd is the main Samba3 daemon and handles the SMB protocol. nmbd provides NetBIOS name server support.

/sbin/smbd -D
/sbin/nmbd -D

Creating users
You can add new Samba users using

smbpassword -a <username>

To be successful, there must be an entry in /etc/passwd corresponding to the user.

Notes on minimal systems
If smbd or nmbd reports smbd: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory, then you are missing the GCC low-level runtime library. You can copy it from your arm-linux-gnueabi cross compiler:

cp /usr/arm-linux-gnueabi/lib/libgcc_s.so.1 /home/export/rootfs/lib
If smbd fails to start, check the logs in /var/log.smbd. If smbd fails to daemonise and there is no error message, potentially you have a user account problem. If you don’t have a /etc/passwd file, create one with a root and nobody user:

root::0:0:root:/root:/bin/bash 
nobody:x:65534:65534:nobody:/nonexistent:/bin/bash
