windows下使用ndk编译grpc

下载grpc

https://github.com/grpc/grpc.git
git checkout release-0_9_1

使用nodejs由build.json生成Android.mk

新建gen-ndk.js，内容如下

var fs = require("fs");
var build = JSON.parse(fs.readFileSync("build.json", "utf8"));

var libs = build.libs;

process.stdout.write('LOCAL_PATH := $(call my-dir)  \n');
process.stdout.write('SRC_PATH := ..\n')

function getGroup(name)
{
    for (var i = 0; i < build.filegroups.length; i++)
        if (build.filegroups[i].name == name)
            return build.filegroups[i];

}

for (var i = 0; i < libs.length; i++) {
    if (libs[i].build == 'all' && libs[i].secure == 'no') {
        process.stdout.write('\n\ninclude $(CLEAR_VARS)\n')
        process.stdout.write('LOCAL_MODULE_TAGS:= optional\n');
        process.stdout.write('LOCAL_MODULE:= ' + libs[i].name + '\n')
        var headers = {};
        headers['include'] = 'include';

        if (libs[i].headers != undefined) {
            for (var j = 0; j < libs[i].headers.length; j++) {
                var path = libs[i].headers[j];
                var last = path.lastIndexOf('/');
                path = path.substr(0, last);
                headers[path] = path;
            }
        }


        if (libs[i].deps !== undefined) {
            process.stdout.write('LOCAL_SHARED_LIBRARIES:=')
            for (var j = 0; j < libs[i].deps.length; j++) {
               process.stdout.write(libs[i].deps[j] + ' ');
            }
            process.stdout.write('\n');
        }

        process.stdout.write('LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog -lz\n');



        process.stdout.write('LOCAL_SRC_FILES:= \\\n');
        if (libs[i].src !== undefined) {
            for (var j = 0; j < libs[i].src.length; j++) {
               process.stdout.write('\t$(SRC_PATH)/' + libs[i].src[j] + ' \\\n');
            }            
        }

        if (libs[i].filegroups !== undefined) {
            for (var j = 0; j < libs[i].filegroups.length; j++) {
                var group = getGroup(libs[i].filegroups[j]);
                for (var k = 0; k < group.src.length; k++)
                    process.stdout.write('\t$(SRC_PATH)/' + group.src[k] + ' \\\n');

                if (group.headers != undefined) {
                    for (var k = 0; k < group.headers.length; k++) {
                        var path = group.headers[k];
                        var last = path.lastIndexOf('/');
                        path = path.substr(0, last);
                        headers[path] = path;
                    }
                }
            }       
        }


        process.stdout.write('\nLOCAL_C_INCLUDES:= \\\n')
        process.stdout.write('\t$(LOCAL_PATH)/../include \\\n');
        process.stdout.write('\t$(LOCAL_PATH)/../ \\\n');
        process.stdout.write('\t$(LOCAL_PATH)/../../protobuf/src \\\n');


        process.stdout.write('\ninclude $(BUILD_SHARED_LIBRARY)\n');


    }
}

建立Application.mk，内容如下

APP_MODULES      := gpr grpc_unsecure grpc++_unsecure
APP_PLATFORM     := android-9
APP_ABI          := armeabi-v7a
APP_STL          := gnustl_static
APP_OPTIM        := release
NDK_TOOLCHAIN_VERSION := clang

APP_CPPFLAGS     := -fexceptions -frtti -std=c++11

编译后得到gpr grpc_unsecure grpc++_unsecure，就是我们所需要的。

遇到的问题：
默认使用grpc库链接得到的程序，运行的时候会提示下面错误，

CANNOT LINK EXECUTABLE: could not load library "libgrpc_unsecure.so" needed by "xxx"; caused by cannot locate symbol "__tls_get_addr" referenced by "libgrpc_unsecure.so"...

做下面的修改就可以了，使用android libthread自己的tls
