### 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:
```
shell
# generate make files
$
cd
[
Milvus root path]/core
$
./build.sh
-l
# 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 build whole milvus project, just run:
```
shell
# start milvus server
$
cd
[
Milvus root path]/core
$
./start_server.sh
```
You also can pull milvus release docker image to launch milvus server.
```
shell
# pull milvus docker image and start milvus server
$
docker pull milvusdb/milvus:latest
$
docker run
--runtime
=
nvidia
-p
19530:19530
-d
milvusdb/milvus:latest
```
To run C++ example, use below command:
```
shell
# run milvus C++ example
$
cd
[
Milvus root path]/core/cmake_build/src/sdk/examples/simple
$
./sdk_simple
```
### Make your own C++ client project
Firstly create a project folder. And copy C++ sdk header and library into the folder.
```
shell
# create project folder
$
mkdir
MyMilvusClient
$
cd
MyMilvusClient
# copy necessary files
$
cp
[
Milvus root path]/core/cmake_build/src/sdk/libmilvus_sdk.so
.
$
cp
[
Milvus root path]/core/src/sdk/include/MilvusApi.h
.
$
cp
[
Milvus root path]/core/src/sdk/include/Status.h .
```
Create a main.cpp under the project folder, and include C++ sdk headers:
```
shell
#include "./MilvusApi.h"
#include "./Status.h"
int main
()
{
// connect to milvus server
std::shared_ptr<milvus::Connection> conn
=
milvus::Connection::Create
()
;
milvus::ConnectParam param
=
{
"127.0.0.1"
,
"19530"
}
;
conn->Connect
(
param
)
;
// put your client code here
milvus::Connection::Destroy
(
conn
)
;
return
0
;
}
```
Create a CMakeList.txt under the project folder, and paste the follow code into the file:
```
shell
cmake_minimum_required
(
VERSION 3.14
)
project
(
test
)
set
(
CMAKE_CXX_STANDARD 14
)
add_executable
(
milvus_client main.cpp
)
target_link_libraries
(
milvus_client
${
PROJECT_SOURCE_DIR
}
/libmilvus_sdk.so
)
```
Build the client project:
```
shell
$
mkdir
cmake_build
$
cd
cmake_build
$
cmake ..
$
make
```
Run your client program:
```
shell
$
./milvus_client
```
