Building on Unix systems
=============================
This doc is trying to cover:
* [Debian/Ubuntu ](#debian-ubuntu ) (contains packaging instructions)
* [Fedora/Centos ](#fedora-centos )
* [Mac OS X ](#mac-os-x )
* [FreeBSD ](#freebsd )
Make sure you have all required dependencies for your system successfully installed.
See [this ](requirements.md ) page for common requirements.
If so then we are ready to go!
Let's clone the repository and start building the i2pd:
git clone https://github.com/PurpleI2P/i2pd.git
Generic build process looks like this (with cmake):
cd i2pd/build
cmake < cmake options > . # see "CMake Options" section below
make # you may add VERBOSE=1 to cmdline for debugging
..or with quick-and-dirty way with just make:
cd i2pd/
make
After successful build i2pd could be installed with:
make install
CMake Options
-------------
Available CMake options(each option has a form of `<key>=<value>` , for more information see `man 1 cmake` ):
* `CMAKE_BUILD_TYPE` build profile (Debug/Release)
* `WITH_BINARY` build i2pd itself
* `WITH_LIBRARY` build libi2pd
* `WITH_STATIC` build static versions of library and i2pd binary
* `WITH_UPNP` build with UPnP support (requires libminiupnp)
* `WITH_AESNI` build with AES-NI support (ON/OFF)
* `WITH_HARDENING` enable hardening features (ON/OFF) (gcc only)
* `WITH_PCH` use pre-compiled header (experimental, speeds up build)
* `WITH_I2LUA` used when building i2lua
* `WITH_WEBSOCKETS` enable websocket server
Also there is `-L` flag for CMake that could be used to list current cached options:
cmake -L
Debian/Ubuntu
-------------
You will need a compiler and other tools that could be installed with `build-essential` package:
sudo apt-get install build-essential
Also you will need a bunch of development libraries:
sudo apt-get install < < EOF
libboost-date-time-dev
libboost-filesystem-dev
libboost-program-options-dev
libboost-system-dev
libssl-dev
zlib1g-dev
EOF
If you need UPnP support miniupnpc development library should be installed (don't forget to rerun CMake with needed option):
sudo apt-get install libminiupnpc-dev
You may also build deb-package with the following:
sudo apt-get install fakeroot devscripts dh-apparmor
cd i2pd
debuild --no-tgz-check -us -uc -b
Fedora/Centos
-------------
You will need a compiler and other tools to perform a build:
sudo yum install make cmake gcc gcc-c++
Also you will need a bunch of development libraries
sudo yum install boost-devel openssl-devel
If you need UPnP support miniupnpc development library should be installed (don't forget to rerun CMake with needed option):
sudo yum install miniupnpc-devel
Latest Fedora systems using [DNF ](https://en.wikipedia.org/wiki/DNF_(software )) instead of YUM by default, you may prefer to use DNF, but YUM should be ok
Centos 7 has CMake 2.8.11 in the official repositories that too old to build i2pd, CMake >=2.8.12 is required.
But you can use cmake3 from the epel repository:
yum install epel-release -y
yum install make cmake3 gcc gcc-c++ miniupnpc-devel boost-devel openssl-devel -y
...and then use 'cmake3' instead 'cmake'.
Mac OS X
--------
Requires [homebrew ](http://brew.sh )
brew install boost libressl
Then build:
make HOMEBREW=1
FreeBSD
-------
For 10.X use clang. You would also need devel/boost-libs, security/openssl and devel/gmake ports.
Type gmake, it invokes Makefile.bsd, make necessary changes there is required.
Branch 9.X has gcc v4.2, that is too old (not supports -std=c++11)
Required ports:
* `devel/cmake`
* `devel/boost-libs`
* `lang/gcc47` (or later version)
To use newer compiler you should set these variables(replace "47" with your actual gcc version):
export CC=/usr/local/bin/gcc47
export CXX=/usr/local/bin/g++47
