### Build C++ sdk

### Build C++ SDK

The C++ sdk source code is under milvus/core/src/sdk. Build entire milvus project will also build the sdk project. 

If you don't want to build entire milvus project, you can do the following steps:

The C++ SDK source code is under milvus/core/src/sdk. Build entire milvus project will also build the C++ SDK project. 

If you don't want to build the entire milvus project, follow below steps:

```shell

 # generate make files

 $ cd [Milvus root path]/core

 $ ./build.sh -l

 # build C++ sdk project

 # build C++ SDK project

 $ cd [Milvus root path]/core/cmake_build

 $ make -C src/sdk

```

### Try C++ example

Firstly you need to launch a milvus server.

If you already build entire milvus project, just run:

Firstly, you need to start a Milvus server.

If you've already built the entire milvus project, just start Milvus server with the following command:

```shell

 # start milvus server

 $ cd [Milvus root path]/core

 $ ./start_server.sh

```

You also can pull milvus release docker image to launch milvus server:

You can also use Docker to start Milvus server:

```shell

 # pull milvus docker image and start milvus server

 $ docker pull milvusdb/milvus:latest

### Make your own C++ client project

Firstly create a project folder. And copy C++ sdk header and library files into the folder.

Create a folder for the project, and copy C++ SDK header and library files into it.

```shell

 # create project folder

 $ mkdir MyMilvusClient

 $ cp [Milvus root path]/core/src/sdk/include/Status.h .

```

Create main.cpp under the project folder, and paste the following code into the file:

Create file main.cpp in the project folder, and copy the following code into it:

```shell

#include "./MilvusApi.h"

#include "./Status.h"

}

```

Create CMakeList.txt under the project folder, and paste the following code into the file:

Create file CMakeList.txt in the project folder, and copy the following code into it:

```shell

 cmake_minimum_required(VERSION 3.14)
