ubuntu下使用ndk编译libevnet

libevent源码编译

源码的获取

http://www.ffmpeg.club/libevent.html 这是看夏老师课堂获取的，以后也要学他的课，所以就用整个源码编译，减少问题出现

编译静态库

https://blog.csdn.net/weixin_28927079/article/details/109380748 大概上是参考这篇博客操作的，额外的修改会在下面提到

在目录下增加Android.mk文件

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_ARM_MODE := arm
LOCAL_MODULE := libevent
ANDROID := true
LIB_SRC := \
event.c \evthread.c \buffer.c \bufferevent.c \bufferevent_filter.c \bufferevent_pair.c \listener.c \bufferevent_ratelim.c \evmap.c \log.c \evutil.c \evutil_rand.c \evutil_time.c \select.c \poll.c \epoll.c \signal.c \event_tagging.c \http.c \evdns.c \evrpc.c \bufferevent_sock.c \strlcpy.c LOCAL_SRC_FILES  := $(LIB_SRC)
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include \$(LOCAL_PATH)/compat
LOCAL_CFLAGS += -pie -fPIE -static -fPIC
include $(BUILD_SHARED_LIBRARY)       # 需要修改为 include $(BUILD_STATIC_LIBRARY)

继续增加Application.mk文件

APP_STL      := c++_static
APP_CPPFLAGS := -frtti -std=c++11
APP_ABI      := armeabi-v7a arm64-v8a   #我这边编译器就是用  arm64-v8a 这个
APP_BUILD_SCRIPT := Android.mk

修改配置文件event2/event-config.h,如果没有就新建一个，这个文件后面也是要修改的

配置完后，开始进行编译，ndk-build.cmd路径根据实际情况修改

     D:\Android-SDK\ndk\21.3.6528147\ndk-build.cmd NDK_PROJECT_PATH=. APP_BUILD_SCRIPT=Android.mk#ndk-build.cmd是android中的可执行文件

第一个报错以及解决

    Android NDK: APP_PLATFORM not set. Defaulting to minimum supported version android-16.[arm64-v8a] Compile        : event <= event.c./event.c:28:10: fatal error: 'evconfig-private.h' file not found#include "evconfig-private.h"^~~~~~~~~~~~~~~~~~~~

解决方法: 把Android.mk当前目录下的\WIN32-Code\nmake\evconfig-private.h拷贝到Android.mk所在目录下

第二个报错以及解决

    ./epoll.c:148:23: error: use of undeclared identifier 'EPOLL_CLOEXEC'epfd = epoll_create1(EPOLL_CLOEXEC);^

解决方法: 将event2/event-config.h目录下的#define EVENT__HAVE_EPOLL_CREATE1 1注释掉

第三个报错以及解决

error: static declaration of ‘arc4random_addrandom’ follows non-static declaration

增加定义 #define EVENT__HAVE_ARC4RANDOM 1

编译结果

在\obj\local\arm64-v8a目录下获得libevent.a

openssl源码编译

https://github.com/aluvalasuman/OpenSSL1.0.1cForAndroid

直接用github上面整理好的工程编译就行了，编译方法和上述一样，最后会生成libcrypto.a和libssl.a

带着openssl编译libevent

修改libevent目录下的Android.mk,增加一行如下
