2.交叉编译

一、libnl 1.1 1.解压libnl-1.1.tar.gz 到指定目录下 ../libnl_pro 2.修改libnl_pro内的文件 **** .../libnl_pro/lib/route/link/vlan.c ****#include //找到这里，新增以下3行代码 #ifndef VLAN_FLAG_REORDER_HDR #define VLAN_FLAG_REORDER_HDR 0x01 #endif3.交叉编译在目录../libnl_pro下执行，#### /home/user1/hong/smdd/pro/libnl/hi3536/ 为对应存放库文件路径 ./configure CC=arm-hisiv300-linux-gcc --host=arm --prefix=/home/user1/hong/smdd/pro/libnl/hi3536/ ./configure CC=arm-histbv310-linux-gcc --host=arm --prefix=/home/user1/hong/smdd/pro/libnl/hi3798/ make clean make make install二、DHCPv6 1.解压dhcpv6-1.2.0.tar.gz 到指定目录下 ../dhcpv6_pro【3536和3798需区分开交叉编译，因此可以复制一个文件如../dhcpv6_pro_hi3798】 2.交叉编译：在../dhcpv6_pro路径下执行, /home/user1/hong/smdd/pro/libnl/hi3798/lib 为上面获取libnl的路径 ./configure LIBNL_CFLAGS=-I/home/user1/hong/smdd/pro/libnl/include LIBNL_LIBS="-L/home/user1/hong/smdd/pro/libnl/hi3798/lib -lnl" CC=arm-histbv310-linux-gcc --host=arm --with-gnu-ld ./configure LIBNL_CFLAGS=-I/home/user1/hong/smdd/pro/libnl/include LIBNL_LIBS="-L/home/user1/hong/smdd/pro/libnl/hi3536/lib -lnl" CC=arm-hisiv300-linux-gcc --host=arm --with-gnu-ld3.对项目下的一些文件必须作出修改 **** ../dhcpv6_pro/config.h ****/* Directory for lease databases and DUID files. */ //#define DB_FILE_PATH "/var/lib/dhcpv6"//David.Milesight modify 14.07.28 #define DB_FILE_PATH "/tmp" /* Directory for PID files. */ //#define PID_FILE_PATH "/var/run/dhcpv6"//David.Milesight modify 14.07.28 #define PID_FILE_PATH "/tmp" /* Define to rpl_malloc if the replacement function should be used. */ //#define malloc rpl_malloc//David /* Define to `int' ifdoes not define. */ /* #undef pid_t */ /* Define to rpl_realloc if the replacement function should be used. */ //#define realloc rpl_realloc//David***** ../dhcpv6_pro/src/dhcp6c.c *******在main()函数中。 #ifndef __DARWIN_DEPRECATED_ATTRIBUTEif (foreground == 0) {#if 0//David//注释这部分代码if (daemon(0, 0) < 0) {err(1, "daemon"); } #endif4.编译获取可执行文件在路径 ../dhcpv6_pro/src 执行make clean 和make就可以在./src下生成对应的可执行文件 dhcp6c备注：libnl路径修改的话请修改makefile以下两行 LIBNL_CFLAGS = -I/home/user1/hong/smdd/pro/libnl/hi3536/include LIBNL_LIBS = -L/home/user1/hong/smdd/pro/libnl/hi3536/lib -lnl三、使用于NVR上首先将../libnl/lib下的libnl.so,libnl.so.1,libnl.so.1.1拷到对应的libs文件里，如./targets/hi3536/app/libs/ 然后将../dhcpv6_pro/src下的dhcp6c拷到对应bin文件里，如./targets/hi3536/app/bin/
