Ubuntu 12.04 LTS 64bit, g++-4.8 | clang++-3.3
[![Build Status](https://travis-ci.org/soonhokong/lean-osx.png?branch=master)](https://travis-ci.org/soonhokong/lean-osx)
Mac OS X 10.8.2, g++-4.8
Requirements
============
- C++11 compatible compiler
- GMP (GNU multiprecision library)
http://gmplib.org/
2013-08-06 00:58:54 +00:00
- MPFR (GNU MPFR Library)
http://www.mpfr.org/
- (optional) gperftools
https://code.google.com/p/gperftools/
- cmake
http://www.cmake.org
Install Packages on Ubuntu
--------------------------
Instructions for installing gperftools on Ubuntu
sudo add-apt-repository ppa:agent-8131/ppa
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install libgoogle-perftools-dev
Instructions for installing gcc-4.8 (C++11 compatible) on Ubuntu
sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
sudo update-alternatives --remove-all gcc
sudo update-alternatives --remove-all g++
sudo apt-get update
sudo apt-get install g++-4.8 -y
sudo apt-get upgrade -y && sudo apt-get dist-upgrade -y
Instructions for installing clang-3.3 (C++11 compatible) on Ubuntu
sudo add-apt-repository ppa:h-rayflood/llvm
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install clang-3.3 clang-3.3-doc
Note that you [still need][1] to have g++-4.8's C++ runtime library to
support some C++11 features that we are using.
You can specify the C++ compiler to use by using ``-DCMAKE_CXX_COMPILER``
option. For example
cmake -DCMAKE_BUILD_TYPE=DEBUG -DCMAKE_CXX_COMPILER=clang++-3.3 ../../src

Install Packages on OS X
------------------------
We assume that you are using [homebrew][homebrew], "The missing package manager for OS X".
[homebrew]: http://brew.sh
Instructions for installing gperftools on OS X 10.8
$ brew install gperftools
Instructions for installing gcc-4.8 (C++11 compatible) on OS X 10.8
$ brew tap homebrew/versions
$ brew install gcc48
Instructions for installing clang-3.3 (C++11 compatible) on OS X 10.8
$ brew install llvm --with-clang --with-asan
Install Packages on Cygwin
--------------------------
Just run cygwin setup.exe (http://cygwin.com/install.html) and make sure that you have installed g++ 4.8.1 (or greater), cmake, gmp and libmpfr.
We have tested Lean using Cygwin for 64-bit versions of Windows.
Build Instructions
==================
Using [CMake][cmake] + Make
---------------------
Instructions for DEBUG build
mkdir -p build/debug
cd build/debug
cmake -DCMAKE_BUILD_TYPE=DEBUG ../../src
make
Instructions for RELEASE build
mkdir -p build/release
cd build/release
cmake -DCMAKE_BUILD_TYPE=RELEASE ../../src
make
Using [CMake][cmake] + [Ninja][ninja]
-------------------------------
[CMake 2.8.11][cmake] supports [Ninja][ninja] build system using
2013-08-01 22:52:02 +00:00
``-G`` option. [Some people report][1] that using [Ninja][ninja] can
reduce the build time, esp when a build is incremental.
