以一个ser2net软件包为例解读openwrt19.07编译文件及luci编译步骤

以一个ser2net软件包为例解读openwrt19.07编译文件及luci编译步骤1、包编译；
第一步拷贝ser2net-3.5.1.tar.gz文件到dl目录，
并在feeds/package/net/下建立ser2net目录，并建立Makefile文件；
//包头信息
PKG_NAME:=ser2net
PKG_VERSION:=3.5.1
PKG_RELEASE:=5
//包位置，会自解压到build_dir/target-mipsel_24kc_musl/ser2net-3.5.1
PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.gz
PKG_SOURCE_URL:=@SF/ser2net

PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.gz
PKG_SOURCE_URL:=@SF/ser2net
//其他信息
PKG_LICENSE:=GPL-2.0-or-later
PKG_LICENSE_FILES:=COPYING

PKG_FIXUP:=autoreconfPKG_INSTALL:=1include $(INCLUDE_DIR)/package.mk//定义包的Luci位置；define Package/ser2net  SECTION:=net  CATEGORY:=Network  TITLE:=Serial to Network Proxy  URL:=https://sourceforge.net/projects/ser2net/endef//包描述define Package/ser2net/description  This project provides a proxy that allows telnet/tcp connections to be made to  serial ports on a machine.endef//定义包的配置文件define Package/ser2net/conffiles/etc/config/ser2net/etc/ser2net.confendef//安装相关文件到相对应的位置；define Package/ser2net/install    $(INSTALL_DIR) $(1)/usr/sbin    $(INSTALL_BIN) $(PKG_INSTALL_DIR)/usr/sbin/ser2net $(1)/usr/sbin/    $(INSTALL_DIR) $(1)/etc    $(INSTALL_CONF) ./files/ser2net.conf $(1)/etc/    $(INSTALL_DIR) $(1)/etc/config    $(INSTALL_CONF) ./files/ser2net.config $(1)/etc/config/ser2net    $(INSTALL_DIR) $(1)/etc/init.d    $(INSTALL_BIN) ./files/ser2net.init $(1)/etc/init.d/ser2netendef$(eval $(call BuildPackage,ser2net))

并在该目录下建立配置文件files目录，建立三个配置文件
ser2net.conf ->运行参数配置文件
ser2net.config ->web配置文件参数
ser2net.init ->启动配置文件
2、luci相关内容编译；
（1）文件目录结构
htdocs -> luci-status->resources->view->ser2net->
leds.js //三个页面的js文件；
proxies.js
settings.js
po ->翻译文件信息；
root ->usr/share/luci-> menu.d ->luci.app-ser2net.json 文件,该文件确定的文件菜单位置，以及菜单页调用的view文件名;
{
"admin/services/ser2net": {
"title": "ser2net",
"action": {
"type": "firstchild"
},
"depends": {
"acl": [ "luci-app-ser2net" ],
"uci": { "ser2net": true }
}
},

            "admin/services/ser2net/settings": {                "title": "Settings",                "order": 1,                "action": {                    "type": "view",                    "path": "ser2net/settings"                }            },            "admin/services/ser2net/proxies": {                "title": "Proxies",                "order": 2,                "action": {                    "type": "view",                    "path": "ser2net/proxies"                }            },            "admin/services/ser2net/leds": {                "title": "LEDs",                "order": 3,                "action": {                    "type": "view",                    "path": "ser2net/leds"                }            }        }    ->usr/share/rpcd/acl.d -> luci-app-ser2net.json    {        "luci-app-ser2net": {            "description": "Grant access to LuCI app ser2net",            "read": {                "uci": [ "ser2net" ]            },            "write": {                "uci": [ "ser2net" ]            }        }    }

（1）编译Makefile 文件内容
include $(TOPDIR)/rules.mk

    LUCI_TITLE:=LuCI Support for ser2net    LUCI_DEPENDS:=+ser2net    PKG_LICENSE:=Apache-2.0    include ../../luci.mk相应内容在luci/luci.mk文件里    拷贝以上htdocs,root,以及po文件内容到相应位置；      define Package/$(PKG_NAME)/install        if [ -d $(PKG_BUILD_DIR)/luasrc ]; then \          $(INSTALL_DIR) $(1)$(LUCI_LIBRARYDIR); \          cp -pR $(PKG_BUILD_DIR)/luasrc/* $(1)$(LUCI_LIBRARYDIR)/; \          $(FIND) $(1)$(LUCI_LIBRARYDIR)/ -type f -name '*.luadoc' | $(XARGS) rm; \          $(if $(CONFIG_LUCI_SRCDIET),$(call SrcDiet,$(1)$(LUCI_LIBRARYDIR)/),true); \          $(call SubstituteVersion,$(1)$(LUCI_LIBRARYDIR)/); \        else true; fi        if [ -d $(PKG_BUILD_DIR)/htdocs ]; then \          $(INSTALL_DIR) $(1)$(HTDOCS); \          cp -pR $(PKG_BUILD_DIR)/htdocs/* $(1)$(HTDOCS)/; \          $(if $(CONFIG_LUCI_JSMIN),$(call JsMin,$(1)$(HTDOCS)/),true); \          $(if $(CONFIG_LUCI_CSSTIDY),$(call CssTidy,$(1)$(HTDOCS)/),true); \        else true; fi        if [ -d $(PKG_BUILD_DIR)/root ]; then \          $(INSTALL_DIR) $(1)/; \          cp -pR $(PKG_BUILD_DIR)/root/* $(1)/; \        else true; fi        if [ -d $(PKG_BUILD_DIR)/src ]; then \          $(call Build/Install/Default) \          $(CP) $(PKG_INSTALL_DIR)/* $(1)/; \        else true; fi    endef
