RocksDB

document：https://github.com/facebook/rocksdb/blob/257b458121b7c684f432838ca0e45c1500744c89/INSTALL.md

platform：ubuntu desktop 18.04

Upgrade your gcc to version at least 4.8 to get C++11 support.

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50
apt-get install g++-4.8
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 50
gcc --version
g++ --version

we can get gcc7.3 and g++7.3 directly in following way

sudo apt-get install build-essential autoconf libtool pkg-config

Install gflags. First, try: sudo apt-get install libgflags-dev If this doesn't work and you're using Ubuntu, here's a nice tutorial: (http://askubuntu.com/questions/312173/installing-gflags-12-04)

sudo apt-get install libgflags-dev

Install snappy. This is usually as easy as: sudo apt-get install libsnappy-dev.

sudo apt-get install -y libsnappy-dev

Install zlib. Try: sudo apt-get install zlib1g-dev.

sudo apt-get install -y zlib1g-dev

Install bzip2: sudo apt-get install libbz2-dev.

sudo apt-get install -y libbz2-dev

Install lz4: sudo apt-get install liblz4-dev.

sudo apt-get install -y liblz4-dev

Install zstandard: sudo apt-get install libzstd-dev.

sudo apt-get install -y libzstd-dev

cryptopp

git clone https://github.com/weidai11/cryptopp.git
cd cryptopp
make
make test
make install

grpc

document：https://github.com/grpc/grpc/blob/master/BUILDING.md platform：ubuntu desktop 18.04

install build essential

sudo apt-get install build-essential autoconf libtool pkg-config

compile

git clone -b $(curl -L https://grpc.io/release) https://github.com/grpc/grpc
cd grpc
git submodule update --init

if there are any errors, then

# vi .gitmodules
[submodule "third_party/gflags"]
	    path = third_party/gflags
	    url = https://github.com/tangmi360/gflags.git
# make
# make install

install protobuf

# cd third_party/protobuf
# make && sudo make install

Set environment

make sure where pkgconfig is on your computer, mine is usr/local/lib/pkgconfig

# export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

set the path of library, otherwise we cannot find where libgrpc++.so.1 is

# vi /etc/ld.so.conf.d/grpc.conf
# add "/usr/local/lib"
# ldconfig

run the example project

cd grpc/examples/cpp/helloworld
make
./greeter_server
./greeter_client
