编译环境

操作系统
xy@ubuntu18xx:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.1 LTS
Release: 18.04
Codename: bionic
交叉编译工具
arm-linux-gcc-4.4.3-20100728.tar.gz

下载和解压

curl -O https://download.samba.org/pub/samba/samba-3.0.37.tar.gz
tar zxvf samba-3.0.37.tar.gz
cd samba-3.0.37/source/

先在X86平台上面进行编译测试：

./configure samba_cv_CC_NEGATIVE_ENUM_VALUES=yes
make
不需要修改，可以直接编译通过
这里用的root用户测试，需要修改一下权限，后面用xy用户编译
root@ubuntu18xx:/home/xy/c/samba# chmod -R 777 .

再交叉编译arm平台

xy@ubuntu18xx:~/c/samba/samba-3.0.37/source$ ./configure samba_cv_CC_NEGATIVE_ENUM_VALUES=yes CC=arm-linux-gcc LD=arm-linux-ld ranlid=arm-linux-ranlid AR=arm-linux-ar --target=arm-linux --host=i686

checking that the C compiler understands volatile… yes
checking that the C compiler understands negative enum values… configure: error: in /home/xy/c/samba/samba-3.0.37/source': configure: error: cannot run test program while cross compiling Seeconfig.log’ for more details.

先修改为no
samba_cv_CC_NEGATIVE_ENUM_VALUES=yes 应该把这个参数修改为no试试的
配置通过

make报错

make编译成功 bin/smbd

机顶盒上面:

创建工作目录：
mkdir /usr/local /usr/local/samba /usr/local/samba/bin /usr/local/samba/lib /usr/local/samba/private /usr/local/samba/var
创建配置文件： vi /usr/local/samba/lib/smb.conf
[global]
workgroup = myworkgroup
server string = samba
netbios name =myarm
guest account=root
security =share
interfaces = eth0
[share]
path = /opt/
guest ok=yes
browseable=yes

bin/smbd 到 开发板的 /usr/local/samba/bin 目录下面；
/usr/local/samba/bin/smbd -D
准备测试文件 cat /proc/cpuinfo > /opt/cpu.txt

在win10中访问测试

打开 \192.168.1.1 提示因为文件共享不安全，所以你不能连接到文件共享
此共享需要旧的 SMB1 协议，它不安全，并且可能使你的系统受到攻击。
你的系统需要 SMB2 或更高版本。 有关解决此问题的详细信息，请参阅：https://go.microsoft.com/fwlink/?linkid=852747

cortana中搜索：启用或关闭Windows功能，选中SMB1.0/CIFS 客户端，重启仍然不能访问，需要3个都安装重启，正常访问\192.168.1.1，无密码提示。
