grpc linux下的编译使用

---

1. 一些工具安装

$ apt-get install build-essential autoconf libtool pkg-config
$ apt-get install libgflags-dev libgtest-dev
$ apt-get install clang libc++-dev

2. 源码下载

 $ git clone -b v1.15.0 https://github.com/grpc/grpc
 $ cd grpc
 $ git submodule update --init

3. 编译

编译的话，直接进入grpc根目录，然后在控制台make即可

$ make

笔者编译的时候，遇到的一些问题

• 编译protobuf的时候失败, 提示

  config.status: error: cannot find input file: `Makefile.in'
  

  这个时候，进入protobuf源码文件, 运行autogen.sh脚本，然后再返回到grpc源码根目录，继续编译即可

  $ cd ./third_party/protobuf
  $ ./autogen.sh
  

• 没有自动编译zlib库
  编译grpc库的时候，并没有自动编译zlib库，所有需要自己手动去编译下

  $ cd ./third_party/zlib
  $ mdkir .build
  $ cd .build
  $ cmake ..
  $ make
  

4. 使用

第一次测试使用的话，可以使用example里面的helloworld

• 先根据helloworld.proto生成pb和grpc.pb文件

$ protoc.exe -I=. --grpc_out=../pb_gen --plugin=protoc-gen-grpc=../../.../../YDK/3rd/grpc-1.15.0/bin/linux/grpc_cpp_plugin helloworld.proto
$ protoc.exe -I=. --cpp_out=../pb_gen helloworld.proto

protoc-gen-grpc 后面跟的是grpc_cpp_plugin二进制路径, 然后在pb_gen文件夹会生成4个文件

helloworld.grpc.pb.h
helloworld.grpc.pb.cc
helloworld.pb.cc
helloworld.pb.h
