问题描述

我在交叉编译一个新手，我被分配任务使用Android补丁的http：//的avahi。组织/票/ 354 编译内核的avahi到Android。 NDK建造的avahi配置的V = 1是成功的，但是当我跑：NDK建造V = 1 NDK_LOG = 2 APP_ABI =armeabi armeabi-V7A，它给人吨警告，也使错误的socket.o

任何建议表示欢迎。

解决方案

您已经下载的补丁是没有及时更新。最新的NDK，R8B，包含文件的Linux / ipv6.h 而无法在早期版本的NDK中找到。不幸的是这种变化NDK，欢迎，因为它是从来没有被记录在案。

这意味着你必须撤销补丁，以 socket.c 文件，通过删除线

  67的#ifdef __BIONIC__
68结构in6_pktinfo {
69结构in6_addr ipi6_addr;
70 INT ipi6_ifindex;
71};
72 #ENDIF
73

从的avahi核心/ socket.c 文件。

I am a newbie in cross compilation and I was assigned the task to use the android patch http://avahi.org/ticket/354 to compile avahi core to android. ndk-build avahi-configure V=1 was successful, but when I ran: ndk-build V=1 NDK_LOG=2 APP_ABI="armeabi armeabi-v7a", it gives tons of warning and also make error on socket.o

Any suggestion is welcomed.

解决方案

The patch you have downloaded is not up-to-date. The latest NDK, r8b, contains the file linux/ipv6.h which could not be found on the earlier versions of NDK. Unfortunately this change to NDK, welcome as it is, has never been documented.

This means that you must undo the patch to socket.c file, by removing the lines 

67  #ifdef __BIONIC__ 
68  struct in6_pktinfo { 
69      struct in6_addr ipi6_addr; 
70      int ipi6_ifindex; 
71  }; 
72  #endif 
73

from avahi-core/socket.c file.
