Compilation

Step 1: install necessery tools

centos7 : 
    yum install gfortran qt4 flex bison mysql-devel mysql
    
ubuntu16.04 : 
    sudo apt-get install gfortran qt4-qmake flex bison libmysqlclient-dev mysql-client
    
cd scripts && sudo ./requirements.sh     

If libmysqlclient_r.so does not exist after installing MySQL Development Files, you need to create a symbolic link:

sudo ln -s /path/to/libmysqlclient.so /path/to/libmysqlclient_r.so

Step 2: build(output to cmake_build folder)

cmake_build/src/milvus_server is the server

cd [sourcecode path]/cpp/thirdparty
git clone git@192.168.1.105:megasearch/knowhere.git
cd knowhere
./build.sh -t Debug
or ./build.sh -t Release

cd [sourcecode path]/cpp
./build.sh -t Debug
or ./build.sh -t Release

If you encounter the following error when building: protocol https not supported or disabled in libcurl

1. Install libcurl4-openssl-dev

2. Install cmake 3.14:

   ./bootstrap --system-curl 
   make 
   sudo make install
   

To build unittest:

./build.sh -u
or
./build.sh --unittest

To run code coverage

apt-get install lcov
./build.sh -u -c

Launch server

Set config in cpp/conf/server_config.yaml

Add milvus/lib to LD_LIBRARY_PATH

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/milvus/lib

Then launch server with config: cd [build output path] start_server.sh stop_server.sh

Launch test_client(only for debug)

If you want to test remote api, you can run sdk example. [build output path]/sdk/examples/grpcsimple/sdk_simple
