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

首先建議大家看好版本,環境,有可能因為小的變化會造成編譯有問題:

 我的環境是

PC  OS: windows10(沒辦法暫時沒機器);

NDK: android-ndk-r17b-windows-x86_64

proto :

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

protoc_person.bat 批處理檔案:

protoc --cpp_out=./ person.proto

具體步驟:

1.下載原始碼

解壓下載的原始碼,找到src目錄,C++的原始碼在這個目錄

2.在src目錄,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目錄,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_C_INCLUDES := $(LOCAL_PATH) \

LOCAL_LDLIBS := -llog -lz

#include $(BUILD_SHARED_LIBRARY)
include $(BUILD_STATIC_LIBRARY)

【注意】:  每個版本可能需要編譯的原始檔不同,要編譯的原始碼在src目錄下的Makefile.am檔案。比如你要編譯protobuf-lite,在Makefile.am檔案中搜索libprotobuf_lite_la_SOURCES,將對應的程式碼直接拷貝到LOCAL_SRC_FILES :=   即可。

4.編譯:切記用命令列編譯 cd 到src 目錄,執行 

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

不要用android studio 編譯,可能會出亂七八糟在問題造成編譯不過,最好在linux下編譯吧。

遇到的問題:

問題1:common.cc中缺少 HAVE_PTHREAD的定義。
解決方案:在common.h中定義一下即可,如下:

#ifndef HAVE_PTHREAD
#define HAVE_PTHREAD
#endif

如果您需要靜態庫,只需要將Android.mk檔案中 BUILD_SHARED_LIBRARY修改為 BUILD_STATIC_LIBRARY即可。
