rocksdb 编译安装 日志

Compilation

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.

• make shared_lib will compile librocksdb.so, RocksDB shared library.

• make check will compile and run all the unit tests

• 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.

• By default the binary we produce is optimized for the platform you‘re compiling on (-march=native). 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:

      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:

      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:

      sudo yum install zlib
      sudo yum install zlib-devel
    

  • Install bzip2:

      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/dupes; 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 two important pre-processing macros: ROCKSDB_LITE and IOS_CROSS_COMPILE.
