Android pppoe

1.android已经自带pppd程序，所以就不用移植pppd了

2.下载rp-pppoe代码
  wget -c http://www.roaringpenguin.com/files/download/rp-pppoe-3.10.tar.gz

3.把rp-pppoe-3.10.tar.gz解压到android的 external目录下

4.cd external/rp-pppoe-3.10/src
  1) ./configure --host=arm-linux
  2) vi config.h
    一、注释掉 #define HAVE_SYS_UIO_H 1 要不然会提示重定义的警告
    二、如果提示 if.c:34:26: error: net/ethernet.h: No such file or directory
       注释掉 #define HAVE_NET_ETHERNET_H 1
    三、我的config.h 内容如下

-------------------- config.h ---------------------------------------------

5.external/rp-pppoe-3.10下创建Android.mk文件， 内容如下

-------------------- Android.mk --------------------------------------------
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_SRC_FILES:=\
    src/pppoe.c \
    src/if.c \
    src/debug.c \
    src/common.c \
    src/ppp.c \
    src/discovery.c \


LOCAL_STATIC_LIBRARIES :=

LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES)
LOCAL_MODULE_TAGS := eng
LOCAL_MODULE := pppoe
LOCAL_C_INCLUDES += $(LOCAL_PATH)/src
LOCAL_CFLAGS += '-DVERSION="3.10"' \
    '-DPPPD_PATH="/system/bin/pppd"'

include $(BUILD_EXECUTABLE)

include $(call all-makefiles-under,$(LOCAL_PATH))

-------------------- end of Android.mk -------------------------------------



错误及解决方法：
1) /dev/pts/目录为空， pppoe 提示找不到文件 /dev.pts/0
  内核配置添加如下选项
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_UNIX98_PTYS=y
CONFIG_DEVPTS_MULTIPLE_INSTANCES=y
CONFIG_LEGACY_PTYS=y
CONFIG_LEGACY_PTY_COUNT=256


2) 提示 pppoe: read (asyncReadFromPPP): Session 8: I/O error
   把内核中PPPOE的所有选项都支持上就万事大吉了
# CONFIG_WAN is not set
CONFIG_PPP=y
CONFIG_PPP_MULTILINK=y
CONFIG_PPP_FILTER=y
CONFIG_PPP_ASYNC=y
CONFIG_PPP_SYNC_TTY=y
CONFIG_PPP_DEFLATE=y
CONFIG_PPP_BSDCOMP=y
CONFIG_PPP_MPPE=y
CONFIG_PPPOE=y
CONFIG_PPPOL2TP=y
CONFIG_PPPOLAC=y
CONFIG_PPPOPNS=y
# CONFIG_SLIP is not set
