WiFidog编译成库

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.mk

 

PKG_NAME:=wifidog_lib

PKG_VERSION:=20130917

 

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

 

include $(INCLUDE_DIR)/package.mk

 

define Package/wifidog_lib

  SECTION:=utils

  CATEGORY:=Utilities

  DEPENDS:=+iptables-mod-extra +iptables-mod-ipopt +iptables-mod-nat-extra +libpthread

  TITLE:=A wireless captive portal solution

endef

 

define 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.

endef

 

define Build/Prepare

      mkdir -p $(PKG_BUILD_DIR)

      $(CP) ./src/* $(PKG_BUILD_DIR)/

endef

 

define Build/Configure

endef

 

define Build/Compile

      $(MAKE) -C $(PKG_BUILD_DIR) \

           CC="$(TARGET_CC)" \

           CFLAGS="$(TARGET_CFLAGS) -Wall" \

           LDFLAGS="$(TARGET_LDFLAGS)"

endef

 

define Package/wifidog_lib/conffiles

/etc/wifidog.conf

endef

 

define 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 = 0

LIB_VERMINOR = 1

LIB_FILENAME = libhttpd.so

 

LIBWIFIDOG_FILENAME = libwifidog.so

 

OBJEXT = o

 

CFLAGS += -Os -pipe -mno-branch-likely -mips32r2 -mtune=34kc -fno-caller-saves -fhonour-copts -Wno-error=unused-but-set-variable -msoft-float

 

LIB_CFLAGS  = $(CFLAGS) -shared -fPIC -DPIC

LIB_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.o

 

DEFS = -DHAVE_CONFIG_H

DEFAULT_INCLUDES = -I.-I..

sysconfdir = /etc

AM_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 -lpthread

 

 

all: Makefile   libhttpd   libwifidog test_wifidog

 

test_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 $@ $<

 

 

clean:

      rm -f  $(LIB_FILENAME)*

 

4. 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
