# How To Install Tahoe

This is the default procedure to install from source. It has been verified to work on Windows, Cygwin, Mac, Linux, and Solaris. It's likely to work on other platforms. If you encounter problems following this procedure, or for more details such as platform-specific instructions, please see install-details.html.

## Satisfy the Dependencies

Prior to installing Tahoe the following must be installed:

1. g++ >= v3.3 -- the Cygwin version of gcc/g++ works for Cygwin and for Windows
2. GNU make
3. Python >= v2.4.2 including development headers i.e. "Python.h"
4. Twisted >= v2.4.0 -- from the Twisted "sumo" source tarball
5. OpenSSL >= v0.9.7, including development headers
6. PyOpenSSL == v0.6
7. Crypto++ >= v5.2.1, including development headers

## Get the Source Code

Tarballs of the source code are available at:

    http://allmydata.org/source/tahoe/allmydata-tahoe-0.8.0.tar.gz

## Install

Unpack the tarball and cd into the top-level directory.

Run make check-deps which verifies that all of the dependencies listed above are installed.

Run make to build Tahoe and some included libraries and install the tahoe executable into a subdirectory of the current directory named bin.

Run make test to verify that it built correctly and passes all tests.

Run bin/tahoe --version to verify that the executable tool runs and prints out the right version number (the "allmydata" version number is the version number of the Tahoe package). This executable can configure and launch your node.

## Run

Now you have the Tahoe source code installed and are ready to use it to form a decentralized filesystem. See running.html for instructions.
