Compilation

Important: If you plan to run RocksDB in production, don't compile using default make or make all. That will compile RocksDB in debug mode, which is much slower than release mode.

RocksDB's library should be able to compile without any dependency installed, although we recommend installing some compression libraries (see below). We do depend on newer gcc/clang with C++11 support.

There are few options when compiling RocksDB:

• [recommended] make static_lib will compile librocksdb.a, RocksDB static library. Compiles static library in release mode.

• make shared_lib will compile librocksdb.so, RocksDB shared library. Compiles shared library in release mode.

• make check will compile and run all the unit tests. make check will compile RocksDB in debug mode.

• make all will compile our static library, and all our tools and unit tests. Our tools depend on gflags. You will need to have gflags installed to run make all. This will compile RocksDB in debug mode. Don't use binaries compiled by make all in production.

• By default the binary we produce is optimized for the platform you're compiling on (-march=native or the equivalent). If you want to build a portable binary, add 'PORTABLE=1' before your make commands, like this: PORTABLE=1 make static_lib

Dependencies

• You can link RocksDB with following compression libraries:

  • zlib - a library for data compression.
  • bzip2 - a library for data compression.
  • snappy - a library for fast data compression.

• All our tools depend on:

  • gflags - a library that handles command line flags processing. You can compile rocksdb library even if you don't have gflags installed.

Supported platforms

• Linux - Ubuntu

  • Upgrade your gcc to version at least 4.7 to get C++11 support.
  • 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)
  • Install snappy. This is usually as easy as: sudo apt-get install libsnappy-dev.
  • Install zlib. Try: sudo apt-get install zlib1g-dev.
  • Install bzip2: sudo apt-get install libbz2-dev.

• Linux - CentOS

  • Upgrade your gcc to version at least 4.7 to get C++11 support: yum install gcc47-c++

  • Install gflags:

    Copy

        wget https://gflags.googlecode.com/files/gflags-2.0-no-svn-files.tar.gz
        tar -xzvf gflags-2.0-no-svn-files.tar.gz
        cd gflags-2.0
        ./configure && make && sudo make install
    

  • Install snappy:

    Copy

        wget https://snappy.googlecode.com/files/snappy-1.1.1.tar.gz
        tar -xzvf snappy-1.1.1.tar.gz
        cd snappy-1.1.1
        ./configure && make && sudo make install
    

  • Install zlib:

    Copy

        sudo yum install zlib
        sudo yum install zlib-devel
    

  • Install bzip2:

    Copy

        sudo yum install bzip2
        sudo yum install bzip2-devel
    

• OS X:

  • Install latest C++ compiler that supports C++ 11:
    • Update XCode: run xcode-select --install (or install it from XCode App's settting).
    • Install via homebrew.
      • If you're first time developer in MacOS, you still need to run: xcode-select --install in your command line.
      • run brew tap homebrew/versions; brew install gcc47 --use-llvm to install gcc 4.7 (or higher).
  • run brew install rocksdb

• iOS:

  • Run: TARGET_OS=IOS make static_lib. When building the project which uses rocksdb iOS library, make sure to define one important pre-processing macro: IOS_CROSS_COMPILE.

• Windows:

  • For building with MS Visual Studio 13 you will need Update 4 installed.
  • Read and follow the instructions at CMakeLists.txt
