Building on Unix systems

Common build/install process from sources:

• git clone https://github.com/PurpleI2P/i2pd.git
• mkdir -p 'i2pd/build/tmp' && cd 'i2pd/build/tmp'
• cmake -DCMAKE_BUILD_TYPE=Release ..
• make
• make install

Available cmake options:

• CMAKE_BUILD_TYPE -- build profile (Debug/Release)
• WITH_AESNI -- AES-NI support (ON/OFF)
• WITH_HARDENING -- enable hardening features (ON/OFF) (gcc only)
• 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 libupnp)
• WITH_PCH -- use pre-compiled header (experimental, speeds up build)

Debian/Ubuntu

For building from source on debian system you will need the following "-dev" packages:

• libboost-chrono-dev
• libboost-date-time-dev
• libboost-filesystem-dev
• libboost-program-options-dev
• libboost-regex-dev
• libboost-system-dev
• libboost-thread-dev
• libssl-dev (e.g. openssl)
• zlib1g-dev (libssl-dev already depends on it)
• libminiupnpc-dev (optional, if WITH_UPNP=ON)

You may also build deb-package with the following:

apt-get install build-essential fakeroot devscripts
cd i2pd
debuild --no-tgz-check # building from git repo

FreeBSD

Branch 9.X has gcc v4.2, that knows nothing about required c++11 standart.

Required ports:

• devel/cmake
• devel/boost-libs
• lang/gcc47 # or later version

To use newer compiler you should set these variables:

export CC=/usr/local/bin/gcc47
export CXX=/usr/local/bin/g++47

Replace "47" with your actual gcc version

Branch 10.X has more reliable clang version, that can finally build i2pd, but i still recommend to use gcc, otherwise you will fight it's bugs by your own.
