1.在package/ utils下创建wifidog_lib目录。在wifidog_lib目录下创建一个文件夹src和一个Makefile文件。Makefile文件编写内容如下：
include $(TOPDIR)/rules.mkPKG_NAME:=wifidog_libPKG_VERSION:=20130917PKG_BUILD_DIR := $(BUILD_DIR)/$(PKG_NAME)include $(INCLUDE_DIR)/package.mkdefine Package/wifidog_lib SECTION:=utils CATEGORY:=Utilities DEPENDS:=+iptables-mod-extra +iptables-mod-ipopt +iptables-mod-nat-extra +libpthread TITLE:=A wireless captive portal solutionendefdefine Package/wifidog_lib/description The Wifidog project is a complete and embeddable captive portal solution for wireless community groups or individuals who wish to open a free Hotspot while still preventing abuse of their Internet connection.endefdefine Build/Prepare mkdir -p $(PKG_BUILD_DIR) $(CP) ./src/* $(PKG_BUILD_DIR)/endefdefine Build/Configureendefdefine Build/Compile $(MAKE) -C $(PKG_BUILD_DIR) \ CC="$(TARGET_CC)" \ CFLAGS="$(TARGET_CFLAGS) -Wall" \ LDFLAGS="$(TARGET_LDFLAGS)"endefdefine Package/wifidog_lib/conffiles/etc/wifidog.confendefdefine Package/wifidog_lib/install $(INSTALL_DIR) $(1)/usr/bin $(INSTALL_BIN) $(PKG_BUILD_DIR)/test_wifidog $(1)/usr/bin/ $(INSTALL_DIR) $(1)/usr/lib $(CP) $(PKG_BUILD_DIR)/libwifidog.so* $(1)/usr/lib/ $(INSTALL_DIR) $(1)/etc $(INSTALL_DATA) $(PKG_BUILD_DIR)/wifidog.conf $(1)/etc/endef$(eval $(call BuildPackage,wifidog_lib))
2.解压wifidog包进入src目录
Tar xzvf wifidog-20130917-440445db60b0c3aff528ea703a828b0567293387.tar.gz –C src
3.在src下创建Makefile文件，内容如下：
LIB_VERMAJOR = 0LIB_VERMINOR = 1LIB_FILENAME = libhttpd.soLIBWIFIDOG_FILENAME = libwifidog.soOBJEXT = oCFLAGS += -Os -pipe -mno-branch-likely -mips32r2 -mtune=34kc -fno-caller-saves -fhonour-copts -Wno-error=unused-but-set-variable -msoft-floatLIB_CFLAGS = $(CFLAGS) -shared -fPIC -DPICLIB_LDFLAGS = $(LDFLAGS) -Wl,-soname,$(LIB_FILENAME).$(LIB_VERMAJOR).$(LIB_VERMINOR)LIBWIFIDOG_LDFLAGS = $(LDFLAGS) -Wl,-soname,$(LIBWIFIDOG_FILENAME).$(LIB_VERMAJOR).$(LIB_VERMINOR)wifidog_OBJECTS = src/conf.$(OBJEXT) src/commandline.$(OBJEXT)\ src/debug.$(OBJEXT) src/fw_iptables.$(OBJEXT) src/firewall.$(OBJEXT) \ src/gateway.$(OBJEXT) src/centralserver.$(OBJEXT) src/http.$(OBJEXT) \ src/auth.$(OBJEXT) src/client_list.$(OBJEXT) src/util.$(OBJEXT) \ src/wdctl_thread.$(OBJEXT) src/ping_thread.$(OBJEXT) src/safe.$(OBJEXT) \ src/httpd_thread.$(OBJEXT) src/wifidogapi.$(OBJEXT)wdctl_OBJECTS = src/wdctl.$(OBJEXT)LIB_OBJ = libhttpd/protocol.o libhttpd/api.o libhttpd/version.o libhttpd/ip_acl.oDEFS = -DHAVE_CONFIG_HDEFAULT_INCLUDES = -I.-I..sysconfdir = /etcAM_CPPFLAGS += \ -I./libhttpd/ \ -DSYSCONFDIR='"$(sysconfdir)"'COMPILE = $(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) $(AM_CPPFLAGS) \ $(CPPFLAGS) $(AM_CFLAGS) $(CFLAGS)LTCOMPILE = $(LIBTOOL) --tag=CC $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) \ --mode=compile $(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) \ $(AM_CPPFLAGS) $(CPPFLAGS) $(AM_CFLAGS) $(CFLAGS)CCLD = $(CC)LINK = $(CCLD) $(AM_CFLAGS) $(CFLAGS) $(AM_LDFLAGS) \ $(LDFLAGS) -o $@wifidog_LDADD = libhttpd/$(LIB_FILENAME).$(LIB_VERMAJOR).$(LIB_VERMINOR)LIBS = -lnsl -lpthreadall: Makefile libhttpd libwifidog test_wifidogtest_wifidog: src/test_wifidog.o libhttpd libwifidog @rm -f test_wifidog $(LINK) src/test_wifidog.o $(LIBWIFIDOG_FILENAME).$(LIB_VERMAJOR).$(LIB_VERMINOR) $(LIBS)wdctl: $(wdctl_OBJECTS) libhttpd @rm -f wdctl $(LINK) $(wdctl_OBJECTS) $(wdctl_LDADD) $(LIBS)wifidog_test: $(wifidog_OBJECTS) libhttpd @rm -f wifidog_test $(LINK) $(wifidog_OBJECTS) $(wifidog_LDADD) $(LIBS) libhttpd:$(LIB_OBJ) ./libhttpd/httpd_priv.h ./libhttpd/httpd.h $(CC) $(LIB_CFLAGS) $(LIB_LDFLAGS) $(LIB_OBJ) $(LIBS) \ -o libhttpd/$(LIB_FILENAME).$(LIB_VERMAJOR).$(LIB_VERMINOR)libwifidog:$(wifidog_OBJECTS) $(wdctl_OBJECTS) $(LIB_OBJ) ./libhttpd/httpd_priv.h ./libhttpd/httpd.h $(CC) $(LIB_CFLAGS) $(LIBWIFIDOG_LDFLAGS) $(LIB_OBJ) $(wifidog_OBJECTS) $(wdctl_OBJECTS) $(LIBS) \ -o $(LIBWIFIDOG_FILENAME).$(LIB_VERMAJOR).$(LIB_VERMINOR).c.o: $(CC) $(DEFS) $(AM_CPPFLAGS) $(DEFAULT_INCLUDES) $(INCLUDES) $(CFLAGS) -MD -fPIC -DPIC -c -o $@ $
修改src下对应的源代码，同时把scripts/init.d/wifidog脚本提供的功能通过lib库提供,这样 lib库需要提供int wifidogstart()，int wifidogstop()，int wifidogreload()，int wifidogrestart()。make package/wifidog_lib/compile V=s进行编译生成libwifidog.so.0.1和测试程序test_wifidog
