Lepton Electronic Design Automation
Copyright (C) 1998-2017 gEDA Developers. Copyright (C) 2017-2019 Lepton Developers.
The GPL Electronic Design Automation (gEDA) project has produced and continues working on a full GPL'd suite and toolkit of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production. Currently, the gEDA project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 30 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.
The gEDA project was started because of the lack of free EDA tools for POSIX systems with the primary purpose of advancing the state of free hardware or open source hardware. The suite is mainly being developed on the GNU/Linux platform with some development effort going into making sure the tools run on other platforms as well.
The Lepton EDA suite (this package) provides schematic capture, netlisting, bill of materials generation, and many other features. It was forked from the gEDA/gaf suite in late 2016.
Tools in the Lepton EDA suite
The major components of the Lepton suite are:
- A library of functions for manipulating Lepton schematics and symbols.
- A schematic editor.
- A spreadsheet-like program for bulk editing of component attributes.
- A highly-flexible, hierarchy-aware utility which parses schematics to generate a number of outputs, including netlists for a wide variety of PCB layout tools. It can also generate bills of materials and DRC reports for your schematics.
- A command-line utility for streamlining the workflow where
'PCB' http://pcb.geda-project.org/ and
lepton-schematicare used together.
- A command-line utility for streamlining the workflow where 'PCB' http://pcb.geda-project.org/ and
- A utility for checking for common errors in schematic symbol files.
- A utility for interactive and batch mode working with Lepton EDA Scheme API, exporting schematics into various formats, and configuring all the programs of the suite.

In order to compile gEDA from the distributed source archives, you must have the following tools and libraries installed:
A C/C++ compiler and standard library (GCC/glibc are recommended).
pkg-configtool for managing shared libraries. http://pkgconfig.freedesktop.org/
Guile ("GNU's Ubiquitous Intelligent Language for Extensions"), version 2.0.0 or later. http://www.gnu.org/software/guile/
GTK+ (the Gimp Toolkit), version 2.24.0 or later. http://www.gtk.org/
gettext, version 0.18 or newer. http://www.gnu.org/software/gettext/
lextool for generating lexical scanners. The
fleximplementation recommended. http://flex.sourceforge.net/
awktool for data processing. GNU Awk (
gawk) is recommended. http://www.gnu.org/software/gawk/
The CPython interpreter, version 2.7, including the development headers. https://www.python.org/downloads/
The following tools and libraries are highly recommended:
The freedesktop.org MIME info database. http://freedesktop.org/Software/shared-mime-info
The freedesktop.org utilities for manipulating
The following tools and libraries are optional:
libstroke, a stroke and gesture recognition library. If this is available,
lepton-schematicwill support mouse gesture recognition. http://www.etla.net/libstroke/
doxygenAPI documentation tool. This is required for building the gEDA developer API documentation, not for the regular user documentation. http://www.doxygen.nl
'Inkscape' or 'ImageMagick' for svg to png or pdf conversion This is required for building the gEDA developer API documentation, not for the regular user documentation. http://inkscape.org/ http://www.imagemagick.org/script/index.php
'Graphviz' for drawing directed graphs. This is required for building the gEDA developer API documentation, not for the regular user documentation. http://www.graphviz.org/

./configureisn't picking it up!"
Many modern operating system distributions split a library into two packages:
libfoopackage, which contains the files necessary to run programs which use
libfoo-develpackage, which contains the files necessary to compile programs which use
If you're having problems, make sure that you have all of the
devel packages installed.
"I have installed two versions of guile, but
./configureuses a wrong one!"
guile binary on the
configure stage, e.g.:
Installation from a source archive
First extract the archive to a sensible place:
tar -xzvf lepton-eda-<version>.tar.gz && cd lepton-eda-<version>
Run the configuration script. You'll probably want to specify a custom directory to install gEDA to, for example:
You can then compile Lepton:
And install it (if you used a
--prefix outside your $HOME directory,
you may need to run this as root):
For more information on installing Lepton, see the
Installation from the git repository
Lepton uses the
git version control system. If you wish to try out
the very latest version of Lepton, you will need to install some extra
tools in addition to the ones listed above:
gitversion control tool, version 1.6 or newer. http://git-scm.com/
GNU Automake, version 1.11.0 or newer. http://www.gnu.org/software/automake/
GNU Autoconf, version 2.60 or newer. http://www.gnu.org/software/autoconf/
GNU Libtool. http://www.gnu.org/software/libtool/
GNU Texinfo documentation system. http://www.gnu.org/software/texinfo/
Note that on some distributions the TeX support for Texinfo is packaged separately.
Once you have these installed, you need to clone the gEDA git repository:
git clone https://github.com/lepton-eda/lepton-eda.git
To generate the configure script, run:
You can then proceed to configure and build Lepton as described above.
Building Lepton developer API documentation
Several of the Lepton libraries and applications have doxygen API
documentation available. To generate the API documentation from the
source code, install doxygen (see Dependencies above.
--enable-doxygen to your
configure command line, i.e.:
To compile the documentation (quite a slow process), run:
The documentation can then be found in:
There are several ways to get help with installing and using Lepton and the rest of the gEDA tools:
Chat with Lepton developers and users at gitter.im. You can sign in there using your Twitter, GitHub or GitLab account (no registration is required to read the messages posted there). This is probably the fastest way to get in touch with us.
The gEDA website http://www.geda-project.org has more extensive information on the gEDA tools, and links to some successful projects which use gEDA.
The gEDA documentation wiki contains a large amount of helpful information. A static copy is included with this distribution; see the
docs/wiki/index.htmlfile. The wiki is accessible online at http://wiki.geda-project.org/.
If the resources above didn't help you resolve your problem, or you are having a design problem that you want to get help with, consider subscribing to and posting your question to the
geda-usermailing list (http://wiki.geda-project.org/geda:mailinglists). You can also browse and search the mailing list archives.
If you have discovered a bug, have a feature request, or have written a patch to Lepton, please create an item on the lepton-eda bug tracker page: https://github.com/lepton-eda/lepton-eda/issues
