protobuf使用（一）android ndk 编译 protobuf-3.6.x windows

标签：ndk google protobuf windows stubs util cc internal

首先建议大家看好版本，环境，有可能因为小的变化会造成编译有问题：

我的环境是

PC OS: windows10（没办法暂时没机器）；

NDK: android-ndk-r17b-windows-x86_64

ProtoBuf : protobuf-3.6.x 下载链接：https://github.com/protocolbuffers/protobuf/tree/3.6.x

代码生成工具： protoc-3.6.1-win32下载链接：https://github.com/protocolbuffers/protobuf/releases/

proto :

syntax = "proto3";
package tutorial;
 
message Person {
   int32 id = 1;
   string name = 2;
   string email = 3;
}

protoc_person.bat 批处理文件：

protoc --cpp_out=./ person.proto

具体步骤：

1.下载源码

解压下载的源码，找到src目录，C++的源码在这个目录

2.在src目录，新建 Application.mk

APP_MODULES      := protobuf
APP_PLATFORM     := android-19
APP_ABI          := armeabi-v7a
APP_STL := c++_static
APP_OPTIM        := release

3.在src目录，新建 Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := protobuf
LOCAL_CFLAGS := -std=c++11 -fexceptions -frtti
LOCAL_MODULE_FILENAME := libprotobuf

LOCAL_EXPORT_C_INCLUDES :=
LOCAL_EXPORT_LDLIBS :=

LOCAL_C_INCLUDES := $(LOCAL_PATH) \
$(LOCAL_PATH)/src

LOCAL_LDLIBS := -llog -lz

#include $(BUILD_SHARED_LIBRARY)
include $(BUILD_STATIC_LIBRARY)

【注意】： 每个版本可能需要编译的源文件不同，要编译的源码在src目录下的Makefile.am文件。比如你要编译protobuf-lite，在Makefile.am文件中搜索libprotobuf_lite_la_SOURCES，将对应的代码直接拷贝到LOCAL_SRC_FILES := 即可。

4.编译：切记用命令行编译 cd 到src 目录，运行

ndk-build NDK_PROJECT_PATH=. APP_BUILD_SCRIPT=./Android.mk NDK_APPLICATION_MK=./Application.mk

protobuf使用（一）android ndk 编译 protobuf-3.6.x windows_Android

不要用android studio 编译，可能会出乱七八糟在问题造成编译不过，最好在linux下编译吧。

遇到的问题：

问题1：common.cc中缺少 HAVE_PTHREAD的定义。
解决方案：在common.h中定义一下即可，如下：

#ifndef HAVE_PTHREAD
#define HAVE_PTHREAD
#endif

如果您需要静态库，只需要将Android.mk文件中 BUILD_SHARED_LIBRARY修改为 BUILD_STATIC_LIBRARY即可。
