无法在Android上编译avahi
作者：互联网
我是交叉编译的新手,我被分配了使用Android补丁http://avahi.org/ticket/354将avahi核心编译为android的任务.
ndk-build avahi-configure V = 1成功,但是当我运行时：ndk-build V = 1 NDK_LOG = 2 APP_ABI =“ armeabi armeabi-v7a”,它发出大量警告,并且在socket.o上也会出错.
任何建议都欢迎.

解决方法:
您下载的补丁不是最新的.最新的NDK r8b包含文件linux / ipv6.h,该文件在NDK的早期版本中找不到.不幸的是,对NDK的这种更改(尽管如此)从未被记录下来.
这意味着您必须通过删除以下行来撤消对socket.c文件的修补程序
67 #ifdef __BIONIC__
68 struct in6_pktinfo {
69 struct in6_addr ipi6_addr;
70 int ipi6_ifindex;
71 };
72 #endif
73
从avahi-core / socket.c文件中.
