arm 添加 samb 文件共享

编译环境: ubunto 12 arm-linux-gcc 4.3.2 arm linux 4.1.36 开发板 2440

测试上传速度，大文件

github源码 https://github.com/samba-team/samba

测试了几个版本，各有问题。

samba-4.6.2 ~ 3.6 需要安装 python 环境，才能编译。4.6 需要 python2.7 ，4.0 3.6 需要 phtyon2.x ，apt-get install 安装的 没有 phtyon.h 还需要编译安装。实在太费时间，不装这个。

samba-2.2.8 编译正常，安装报错 codepages 不能编译，后面有介绍解决方法， 解决了 codepages 以后，启动 报错 Unable to open printcap file /etc/printcap for read!
Failed to setup RT_SIGNAL_LEASE handler ,  touch /etc/printcap 可以解决，但是 Failed to setup RT_SIGNAL_LEASE handler还是出错。

samba-3.4.17 编译，正常使用。 下载地址 ： https://github.com/samba-team/samba/archive/samba-3.4.17.tar.gz

下载好解压 cd source3

./autogen.sh
./configure  --bindir=/usr/local/samba --prefix=/usr/local/samba
make CC=arm-linux-gcc
make install

将编译出来的文件全复制到 开发板nfs 文件系统中
cp /usr/local/samba /home/nfs/usr/local/ -rfd
还需要复制 so 库文件 到开发板 nfs 文件系统中
cp /usr/local/samba/lib/*so* /home/nfs/lib/ -d

修改 examples/smb.conf.default  改名为 smb.conf 上传到 开发板 etc 下

smb.conf 红字部分是修改的

 # This is the main Samba configuration file. You should read the
 # smb.conf() manual page in order to understand the options listed
 # here. Samba has a huge number of configurable options (perhaps too
 # many!) most of which are not shown in this example
 #
 # For a step to step guide on installing, configuring and using samba,
 # read the Samba-HOWTO-Collection. This may be obtained from:
 #  http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
 #
 # Many working examples of smb.conf files can be found in the
 # Samba-Guide which is generated daily and can be downloaded from:
 #  http://www.samba.org/samba/docs/Samba-Guide.pdf
 #
 # Any line which starts with a ; (semi-colon) or a # (hash)
 # is a comment and is ignored. In this example we will use a #
 # for commentry and a ; for parts of the config file that you
 # may wish to enable
 #
 # NOTE: Whenever you modify this file you should run the command "testparm"
 # to check that you have not made any basic syntactic errors.
 #
 #======================= Global Settings =====================================

 # values are share, user, server, domain and ads. Most people will want
 # user level security. See the Samba-HOWTO-Collection for details.

 # This option is important for security. It allows you to restrict
 # connections to machines which are on your local network. The

在arm 开发板上，使用 -i -s 启动，这样将错误信息打印到控制台，方便调试
/usr/local/samba/sbin/smbd -i -s /etc/smb.conf

ARM 启动出错
/ # /usr/local/samba/sbin/smbd -i -s /etc/smb.conf
smbd version 3.4.17 started.

ERROR: failed to setup guest info.

需要创建一个用户 （在开发板上执行）

如果没有 /etc/passwd
也需要创建一个
touch /etc/passwd

如果没有用户，需要创建一个用户
adduser root

创建软链（在开发板上执行）
ln -s /usr/local/samba/sbin/smbd /usr/bin/smbd

最后测试正常后，将 smb.conf 复制到 /usr/local/samba/lib/ 下

并修改自启动文件
/etc/init.d/rcS
#添加 开机自动运行
smbd
bftpd -d

最后补充一下

出现错误2.2.8 的 错误解决方法
Installing codepage files in /usr/local/samba/lib/codepages
Creating codepage file /usr/local/samba/lib/codepages/codepage.437
/usr/local/samba/make_smbcodepage: 1: /usr/local/samba/make_smbcodepage: Syntax error: word unexpected (expecting ")")
Creating unicode map /usr/local/samba/lib/codepages/unicode_map.437
/usr/local/samba/make_unicodemap: 1: /usr/local/samba/make_unicodemap: Syntax error: word unexpected (expecting ")")

出错原因是因为 make_unicodemap 和 make_smbcodepage 是 使用 编译生成后的文件，而这2个文件是 使用 arm-linux-gcc 编译的 在 ubunto 上无法执行。

解决方法是，在 arm 开发板上运行转码功能，将 源码中的 codepages 文件夹复制到 arm 开发板上 samba 的目录中 /usr/local/samba ，执行以下 我编写的 shell 。

arm_installcp.sh

 #!/bin/sh
 #author: ningdi date:2017-04-20 15:20
 srcdir=$(pwd)
 BINDIR=$(pwd)
 CODEPAGEDIR=$(pwd)/lib/codepages
 # The current codepage definition list.
 CODEPAGELIST="437 737 775 850 852 861 932 866 949 950 936 1251 ISO8859-1 ISO8859-2 ISO8859-5
 ISO8859-7 KOI8-R 857 ISO8859-9 ISO8859-13 ISO8859-15 1125 KOI8-U"
 for p in $(echo $CODEPAGELIST|tr " " "\n");
 do
     echo ${srcdir}/codepages/codepage_def.$p
     if [ -f ${srcdir}/codepages/codepage_def.$p ]; then
         echo Creating codepage file $CODEPAGEDIR/codepage.$p
     $BINDIR/make_smbcodepage c $p ${srcdir}/codepages/codepage_def.$p $CODEPAGEDIR/codepage.$p
 fi
 if [ -f ${srcdir}/codepages/CP${p}.TXT ]; then
     echo Creating unicode map $CODEPAGEDIR/unicode_map.$p
         $BINDIR/make_unicodemap $p ${srcdir}/codepages/CP${p}.TXT $CODEPAGEDIR/unicode_map.$p
 fi
 done

执行后就会在 ARM 文件系统中 生成编码文件 /lib/codepages
