libevent for android

1. 准备工作

1.1 原材料

libevent-2.0.22-stable

1.2 编译环境

ubuntu-12.04

ndk-r9d

2. 编译步骤

下载解压缩libevent文件

wget http://sourceforge.net/projects/levent/files/libevent/libevent-2.0/libevent-2.0.22-stable.tar.gz
tar -zxf libevent-2.0.22-stable.tar.gz

创建一个event-config.h文件

cd libevent-2.0.22-stable/
mkdir -p ARM-Code/event2/
vim ARM-Code/event2/event-config.h

编辑event-config.h

创建Android.mk文件

vim Android.mk

编写Android.mk文件

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_ARM_MODE := arm
LOCAL_MODULE := eventcore
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 \
select.c \
poll.c \
epoll.c \
signal.c \
event_tagging.c \
http.c \
evdns.c \
evrpc.c \
bufferevent_sock.c

LOCAL_SRC_FILES := $(LIB_SRC)
LOCAL_C_INCLUDES := \
$(LOCAL_PATH)/include \
$(LOCAL_PATH)/compat \
$(LOCAL_PATH)/ARM-Code
include $(BUILD_SHARED_LIBRARY)

创建ndk项目文件

mkdir jni
vim jni/Android.mk
vim jni/Application.mk

编辑jni/Android.mk文件

include $(CLEAR_VARS)
include $(APP_PROJECT_PATH)/Android.mk

编辑jni/Application.mk

APP_PROJECT_PATH := $(call my-dir)/../

APP_STL:=gnustl_static   # 根据自己的需要修改

APP_ABI := armeabi armeabi-v7a
APP_PLATFORM := android-

最后ndk-build就可以了

ndk-build
