WifiDog移植到Ralink_ApSoC_SDK_4210过程记录

configure的配置体系过于复杂，没有弄懂，只好动用brute force了。

借鉴了Ralink_ApSoC_SDK_4210(以后简称SDK)中ntfs-3g、snmpd的结构和Makefile

顶层Makefile内容：

#manfeel, port wifidog to ralink sdk

DIRS = libhttpd src

all romfs:

    for i in $(DIRS) ; do make -C $$i $@ || exit $?; done

clean:

    for i in $(DIRS) ; do make -C $$i clean ; done

libhttpd中的Makefile内容：

#manfeel, port wifidog to ralink sdk

OBJS = api.o ip_acl.o protocol.o version.o

LIBRARY = libhttpd.a

all: $(LIBRARY)

test:

romfs:

$(LIBRARY): $(OBJS)

    $(AR) rcv $@ $(OBJS)

    -$(RANLIB) $@

clean::

    $(RM) $(OBJS) $(LIBRARY)

src中的Makefile内容：

#manfeel, port wifidog to ralink sdk

WIFIDOG_OBJS =     auth.o client_list.o conf.o firewall.o gateway.o httpd_thread.o safe.o \

                centralserver.o  commandline.o  debug.o  fw_iptables.o  http.o     ping_thread.o   util.o  wdctl_thread.o

WDCTL_OBJS = wdctl.o

CFLAGS += -I../libhttpd 

USELIBS = ../libhttpd/libhttpd.a $(ROOTDIR)/lib/libpthread/libpthread.a

all: wifidog wdctl

test:

wifidog: $(WIFIDOG_OBJS) $(USELIBS)

    $(CC) $(LDFLAGS) -static -o $@ $(WIFIDOG_OBJS) $(USELIBS) $(LDLIBS)

wdctl: $(WDCTL_OBJS)

    $(CC) $(LDFLAGS) -static -o $@ $(WDCTL_OBJS) $(LDLIBS)

romfs:

    $(ROMFSINST) /usr/bin/wifidog

    $(ROMFSINST) /usr/bin/wdctl

    $(ROMFSINST) ../fs/wifidog-init /usr/bin/wifidog-init

    $(ROMFSINST) ../fs/wifidog.conf /etc_ro/wifidog.conf

    $(ROMFSINST) ../fs/wifidog-msg.html /etc_ro/wifidog-msg.html

    mkdir -p $(ROOTDIR)/romfs/etc_ro/init.d

    $(ROMFSINST) ../fs/init.d/wifidog /etc_ro/init.d/wifidog

clean:

    -rm -f $(EXEC) *.gdb *.elf *.o

注意：

1.SDK中没有init.d目录，只有/etc_ro/rcS脚本：

2.romfs中的内容，由vendors/Ralink/MT7620中的Makefile生成

3.ln命令默认没有打开！要在busybox的Coreutils里面打开。

4.rcS中加入wifidog相关内容

#!/bin/sh

mount -a

mkdir -p /var/run

cat /etc_ro/motd

#manfeel added

if [ ! -e /etc/wifidog.conf ] ; then

    ln -s /etc_ro/wifidog-msg.html /etc/wifidog-msg.html

    cp /etc_ro/wifidog.conf /etc/wifidog.conf

fi

nvram_daemon&

# run wifidog background and wait goahead finished

# but the following line does'nt work, cause goahead never finish

#(goahead& wait) && wifidog&

(sleep 30 & wait) && wifidog

#for telnet debugging

telnetd

#for syslogd

mkdir -p /var/log

#for cpe_app

ln -s /etc_ro/init.d /etc/init.d

ln -s /etc_ro/cron /etc/cron

编译之后，运行，发现iptables报错，原来是内核的iptables配置不全。

 

iptables v1.4.10: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

修改内核：

烧录运行，又报：iptables: No chain/target/match by that name.

MARK,MAC都要选中，

*** Xtables matches ***     的所有match support最好全选中.

<*>   "state" match support 必须选中（因为wifidog要用到-m state）

 

  至此，整个移植过程结束。
