## 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](http://www.zlib.net/) - a library for data compression.
- [bzip2](http://www.bzip.org/) - a library for data compression.
- [snappy](https://code.google.com/p/snappy/) - a library for fast
data compression.
* All our tools depend on:
- [gflags](https://gflags.github.io/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](http://brew.sh/).
* 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 two important pre-processing macros: `ROCKSDB_LITE` and `IOS_CROSS_COMPILE`.
