编译环境可参照上面原文，亦可参照之前的BLOG配置，此处略
下载sshpass原码并解压到/openwrt/package/sshpass/src：
mkdir -p /openwrt/package/sshpass wget http://sourceforge.net/projects/sshpass/files/sshpass/1.06/sshpass-1.06.tar.gz tar zxvf sshpass-1.06.tar.gz mv sshpass-1.06 /openwrt/package/sshpass/src
主要是下面是新建Makefile内容：
include $(TOPDIR)/rules.mk # Name and release number of this package PKG_NAME:=sshpass PKG_RELEASE:=1.06 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/* $(PKG_BUILD_DIR)/ endef TARGET_LDFLAGS+= -L$(TOOLCHAIN_DIR)/usr/lib -L$(TOOLCHAIN_DIR)/lib -Wl,-rpath=$(TOOLCHAIN_DIR)/lib # 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))然后编译
如果之前编译过整体环境，可以用make package/sshpass/compile -j 1 V=s
如果之前未编译过整体环境，那就make menuconfig起一步步来
