## 2 Installation ¶

Installation of Lepton is pretty simple on many operating systems and distributions supporting pre-built binary packages. Just use your favorite package manager to install the package. For example, on Debian or Ubuntu, you could use `synaptic`, `apt-get`, or `aptitude` for installation. It doesn’t matter which interface you use, GUI or CLI. For instance:

    sudo aptitude install lepton-eda

However, in some cases or on some systems you may want to install Lepton from source code. The order is as follows.

- Download the source code:
- Compile it and install:

      cd the-directory-with-lepton-eda
      autoreconf -ivf && ./configure && make && sudo make install

  Call for `autoreconf` is not needed if you download sources as a tarball of some version.

- In some cases, when, for example, a new library is installed, you may need to launch `ldconfig` as well:

      sudo ldconfig
