Building on Unix systems
=============================
First of all we need to make sure that all dependencies are satisfied.
This doc is trying to cover:
* [Debian/Ubuntu](#debian-ubuntu) (contains packaging instructions)
* [Fedora/Centos](#fedora-centos)
* [Fedora/Centos](#mac-os-x)
* [FreeBSD](#freebsd)
Make sure you have all required dependencies for your system successfully installed.
If so then we are ready to go!
Let's clone the repository and start building the i2pd:
```bash
git clone https://github.com/PurpleI2P/i2pd.git
cd i2pd/build
cmake -DCMAKE_BUILD_TYPE=Release # more options could be passed, see "CMake Options"
make # you may add VERBOSE=1 to cmdline for debugging
```
After successfull build i2pd could be installed with:
```bash
make install
```
or you can just use 'make' once you have all dependencies (boost and openssl) installed
```bash
git clone https://github.com/PurpleI2P/i2pd.git
cd i2pd
make
```
Debian/Ubuntu
-------------
You will need a compiler and other tools that could be installed with `build-essential` package:
```bash
sudo apt-get install build-essential
```
Also you will need a bunch of development libraries:
```bash
sudo apt-get install \
libboost-chrono-dev \
libboost-date-time-dev \
libboost-filesystem-dev \
libboost-program-options-dev \
libboost-system-dev \
libboost-thread-dev \
libssl-dev
```
If you need UPnP support (don't forget to run CMake with `WITH_UPNP=ON`) miniupnpc development library should be installed:
```bash
sudo apt-get install libminiupnpc-dev
```
You may also build deb-package with the following:
```bash
sudo apt-get install fakeroot devscripts
cd i2pd
debuild --no-tgz-check
```
Fedora/Centos
-------------
You will need a compiler and other tools to perform a build:
```bash
sudo yum install make cmake gcc gcc-c++
```
*Latest Fedora system 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*
Also you will need a bunch of development libraries
```bash
sudo yum install boost-devel openssl-devel
```
If you need UPnP support (don't forget to run CMake with `WITH_UPNP=ON`) miniupnpc development library should be installed:
```bash
miniupnpc-devel
```
> *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:
> ```bash
> yum install epel-release -y
> yum install make cmake3 gcc gcc-c++ miniupnpc-devel boost-devel openssl-devel -y
> cmake3 -DWITH_LIBRARY=OFF -DWITH_UPNP=ON -DWITH_HARDENING=ON -DBUILD_SHARED_LIBS:BOOL=OFF
> make
> ```
MAC OS X
--------
Requires [homebrew](http://brew.sh/)
```bash
brew install libressl boost
```
Then build:
```bash
make HOMEBREW=1
```
FreeBSD
-------
For 10.X use clang. You would also need boost and openssl ports.
Type gmake, it invokes Makefile.bsd, make necessary changes there is required.
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(replace "47" with your actual gcc version):
```bash
export CC=/usr/local/bin/gcc47
export CXX=/usr/local/bin/g++47
```
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 libupnp)
* `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)
Also there is `-L` flag for CMake that could be used to list current cached options:
```bash
cmake -L
```
