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 核心编译到 android 的任务。ndk-build avahi-configure V=1 成功，但是当我运行：ndk-build V=1 NDK_LOG=2 APP_ABI="armeabi armeabi-v7a" 时，它会发出大量警告，并且在 socket.o 上也会出错

欢迎任何建议。

您下载的补丁不是最新的。最新的 NDK r8b 包含linux/ipv6.h在早期版本的 NDK 上找不到的文件。不幸的是，这种对 NDK 的更改，尽管很受欢迎，但从未被记录在案。

这意味着您必须socket.c通过删除行来撤消对文件的补丁

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。

Application.mk使用以下内容创建：

APP_OPTIM := release
APP_PLATFORM := android-7
APP_STL := gnustl_static
APP_CPPFLAGS += -frtti 
APP_CPPFLAGS += -fexceptions
APP_CPPFLAGS += -DANDROID
APP_ABI := armeabi armeabi-v7a
APP_MODULES := avahi_static

APP_ABI="armeabi armeabi-v7a"然后在你的ndk-build命令中省略。

1.tar avahi-0.6.31
2.patch -p1 < 0001-Add-Android-support.patch (http://avahi.org/ticket/354)
patch -p1 < 0002-Add-uninstalled.pc.in-files.patch 

3.cd avahi-0.6.31 ./configure --sysconfdir=/etc --localstatedir=/var make 

4.cd the subdirectories make Android.mk 

then,you will see Android.mk in all the subdirectories.


5.ndk-build V=1 NDK_LOG=2 APP_ABI="armeabi armeabi-v7a"
