安装编译环境：

apt-get install build-essential libncurses5-dev zlib1g-dev

下载交叉编译环境及sshpass源码：

wget http://downloads.openwrt.org/backfire/10.03.1/brcm63xx/OpenWrt-SDK-brcm63xx-for-Linux-i686-gcc-4.3.3%2bcs_uClibc-0.9.30.1.tar.bz2
tar jxvf OpenWrt-SDK-brcm63xx-for-Linux-i686-gcc-4.3.3+cs_uClibc-0.9.30.1.tar.bz2 
mkdir -p OpenWrt-SDK-brcm63xx-for-Linux-i686-gcc-4.3.3+cs_uClibc-0.9.30.1/package/sshpass
cd OpenWrt-SDK-brcm63xx-for-Linux-i686-gcc-4.3.3+cs_uClibc-0.9.30.1/package/sshpass
wget http://sourceforge.net/projects/sshpass/files/sshpass/1.05/sshpass-1.05.tar.gz
tar zxvf sshpass-1.05.tar.gz
mv sshpass-1.05 src

sshpass目录新建Makefile文件：

include $(TOPDIR)/rules.mk

# Name and release number of this package
PKG_NAME:=sshpass
PKG_RELEASE:=1.05

PKG_BUILD_DIR := $(BUILD_DIR)/$(PKG_NAME)

include $(INCLUDE_DIR)/package.mk

define Package/sshpass
    SECTION:=utils
    CATEGORY:=Utilities
    TITLE:=sshpass
endef

define Package/sshpass/description
    Sshpass is a tool for non-interactivly performing password authentication with SSH's
endef

# Specify what needs to be done to prepare for building the package.
define Build/Prepare
    mkdir -p $(PKG_BUILD_DIR)
    $(CP) ./src/* $(PKG_BUILD_DIR)/
endef


# Specify where and how to install the program.
define Package/sshpass/install
    $(INSTALL_DIR) $(1)/bin
    $(INSTALL_BIN) $(PKG_BUILD_DIR)/sshpass $(1)/bin/
endef

# This line executes the necessary commands to compile our program.
$(eval $(call BuildPackage,sshpass))

编译sshpass：

cd ../
make package/sshpass/compile

编译成功的程序文件：

ls bin/brcm63xx/packages/
Packages  Packages.gz  sshpass_1.05_brcm63xx.ipk

编译过程中如遇到以下错误：

staging_dir/toolchain-mips_r2_gcc-4.3.3+cs_uClibc-0.9.30.1/usr/lib/libc.so: undefined reference to `_dl_app_init_array’

需修改：

TARGET_LDFLAGS:=-L$(STAGING_DIR)/usr/lib -L$(STAGING_DIR)/lib

为：

TARGET_LDFLAGS+= -L$(TOOLCHAIN_DIR)/usr/lib -L$(TOOLCHAIN_DIR)/lib -Wl,-rpath=$(TOOLCHAIN_DIR)/lib

sshpass使用：

sshpass -p pass ssh -p 22 -o StrictHostKeyChecking=no root@haiyun.me 'uptime'
