Building KiCad from Source

If you are a user and not a developer, please consider using one of the prebuilt packages of KiCad which can be found at the download page on the KiCad website. Building KiCad from source is not for the faint of heart and is not recommended unless you have reasonable software development experience. This document contains the instructions on how to build KiCad from source on the supported platforms. It is not intended as a guide for installing or building library dependencies. Please consult your platforms documentation for installing packages or the source code when building the library dependencies. Currently the supported platforms are Windows Versions 7-10, just about any version of Linux, and OSX 10.7-10.10. You may be able to build KiCad on other platforms but it is not supported. On Windows and Linux the GNU GCC is the only supported compiler and on OSX Clang is the only supported compiler.

[TOC]

Development Tools

Before you begin building KiCad, there are a few tools required in addition to your compiler. Some of these tools are required to build from source and some are optional.

CMake Build Configuration Tool

CMake is the build configuration and makefile generation tool used by KiCad. It is required.

GIT Version Control System

The official source code repository is hosted on Launchpad and requires git to get the latest source. If you prefer to use GitHub there is a read only mirror of the official KiCad repository. Do not submit pull requests to GitHub. Changes should be sent to the KiCad developer's mailing list as an attached patch with [PATCH] at the beginning of the subject.

Doxygen Code Documentation Generator

The KiCad source code is documented using Doxygen which parses the KiCad source code files and builds a dependency tree along with the source documentation into HTML. Doxygen is only required if you are going to build the KiCad documentation.

SWIG Simplified Wrapper and Interface Generator

SWIG is used to generate the Python scripting language extensions for KiCad. SWIG is not required if you are not going to build the KiCad scripting extension.

Library Dependencies

This section includes a list of library dependencies required to build KiCad. It does not include any dependencies of the libraries. Please consult the library's documentation for any additional dependencies. Some of these libraries are optional depending on you build configuration. This is not a guide on how to install the library dependencies using you systems package management tools or how to build the library from source. Consult the appropriate documentation to perform these tasks.

wxWidgets Cross Platform GUI Library##

wxWidgets is the graphical user interface (GUI) library used by KiCad. The current minimum version is 3.0.0. However, 3.0.2 should be used whenever possible as there are some known bugs in prior versions that can cause problems on some platforms. Please note that there are also some platform specific patches that must be applied before building wxWidgets from source. These patches can be found in the patches folder in the KiCad source. These patches are named by the wxWidgets version and platform name they should be applied against. wxWidgets must be built with the --with-opengl option. If you installed the packaged version of wxWidgets on your system, verify that it was built with this option.

Boost C++ Libraries

The Boost C++ library is required only if you intend to build KiCad with the system installed version of Boost instead of the default internally built version. If you use the system installed version of Boost, version 1.56 or greater is required. Please note there are some platform specific patches required to build a working Boost library. These patches can be found in the patches folder in the KiCad source. These patches are named by the platform name they should be applied against.

GLEW OpenGL Extension Wrangler Library

The OpenGL Extension Wrangler is an OpenGL helper library used by the KiCad graphics abstraction library [GAL] and is always required to build KiCad.

GLM OpenGL Mathematics Library

The OpenGL Mathematics Library is an OpenGL helper library used by the KiCad graphics abstraction library [GAL] and is always required to build KiCad.

GLUT OpenGL Utility Toolkit Library

The OpenGL Utility Toolkit is an OpenGL helper library used by the KiCad graphics abstraction library [GAL] and is always required to build KiCad.

Cairo 2D Graphics Library

The Cairo 2D graphics library is used as a fallback rendering canvas when OpenGL is not available and is always required to build KiCad.

Python Programming Language

The Python programming language is used to provide scripting support to KiCad. It only needs to be install if the KiCad scripting build configuration option is enabled.

wxPython Library

The wxPython library is used to provide a scripting console for Pcbnew. It only needs to be installed if the wxPython scripting build configuration option is enabled. When building KiCad with wxPython support, make sure the version of the wxWidgets library and the version of wxPython installed on your system are the same. Mismatched versions have been known to cause runtime issues.

Curl Multi-Protocol File Transfer Library

The Curl Multi-Protocol File Transfer Library is used to provide secure internet file transfer access for the GitHub plug in. This library only needs to be installed if the GitHub plug build option is enabled.

KiCad Build Configuration Options

KiCad has many build options that can be configured to build different options depending on the availability of support for each option on a given platform. This section documents these options and their default values.

Advanced Graphics Context

The USE_WX_GRAPHICS_CONTEXT option replaces wxDC with wxGraphicsContext for graphics rendering. This option is disabled by default. Warning: the is experimental and has not been maintained so use at your own risk.

Graphics Context Overlay

The USE_WX_OVERLAY option is used to enable the optional wxOverlay class for graphics rendering on OSX. This is enabled on OSX by default and disabled on all other platforms.

Scripting Support

The KICAD_SCRIPTING option is used to enable building the Python scripting support into Pcbnew. This options is disabled by default.

Scripting Module Support

The KICAD_SCRIPTING_MODULES option is used to enable building and installing the Python modules supplied by KiCad. This option is disabled by default.

wxPython Scripting Support

The KICAD_SCRIPTING_WXPYTHON option is used to enable building the wxPython interface into Pcbnew including the wxPython console. This option is disabled by default.

GitHub Plugin

The BUILD_GITHUB_PLUGIN option is used to control if the GitHub plug in is built. This option is enabled by default.

Integrated Spice simulator

The KICAD_SPICE option is used to control if the Spice simulator interface for eeschema is built. When this option is enabled, it requires ngspice to be available as a shared library. This option is disabled by default.

New schmatic file format

The KICAD_USE_SCH_IO_MANAGER option is used to control if the new Eeschema I/O manager for handling schematic and symbol library I/O is enabled. This option is disabled by default.

STEP/IGES support for the 3D viewer

The KICAD_USE_OCE is used for the 3D viewer plugin to support STEP and IGES 3D models. Build tools and plugins related to OpenCascade Community Edition (OCE) are enabled with this option. When enabled it requires [OCE][] to be available, and the location of the installed OCE libary to be passed via the OCE_DIR flag. This option is disabled by default.

Demos and Examples

The KiCad source code includes some demos and examples to showcase the program. You can choose whether install them or not with the KICAD_INSTALL_DEMOS option. You can also select where to install them with the KICAD_DEMOS variable. On Linux the demos are installed in $PREFIX/share/kicad/demos by default.

Getting the KiCad Source Code

There are several ways to get the KiCad source. If you want to build the stable version you can down load the source archive from the KiCad Launchpad developers page. Use tar or some other archive program to extract the source on your system. If you are using tar, use the following command:

tar -xzf kicad_src_archive.tar.gz

If you are contributing directly to the KiCad project on Launchpad, you can create a local copy on your machine by using the following command:

git clone -b master https://git.launchpad.net/kicad

Here is a list of source links:

Stable release archive: https://launchpad.net/kicad/4.0/4.0.2/+download/kicad-4.0.2.tar.xz

Development branch: https://code.launchpad.net/~kicad-product-committers/kicad/+git/product-git/+ref/master

GitHub mirror: https://github.com/KiCad/kicad-source-mirror

Building KiCad on Linux

To perform a full build on Linux, run the following commands:

cd <your kicad source mirror>
mkdir -p build/release
mkdir build/debug               # Optional for debug build.
cd build/release
cmake -DCMAKE_BUILD_TYPE=Release \
      -DKICAD_SCRIPTING=ON \
      -DKICAD_SCRIPTING_MODULES=ON \
      -DKICAD_SCRIPTING_WXPYTHON=ON \
      ../../
make
sudo make install

If the CMake configuration fails, determine the missing dependencies and install them on your system. By default, CMake sets the install path on Linux to /usr/local. Use the CMAKE_INSTALL_PREFIX option to specify a different install path.

Building KiCad on Windows

The preferred Windows build environment is MSYS2. The MinGW build environment is still supported but it is not recommended because the developer is responsible for building all of the dependencies from source which is a huge and frustrating undertaking. The MSYS2 project provides packages for all of the require dependencies to build KiCad. To setup the MSYS2 build environment, depending on your system download and run either the MSYS2 32-bit Installer or the MSYS2 64-bit Installer. After the installer is finished, update to the latest package versions by running the msys2_shell.bat file located in the MSYS2 install path and running the command pacman -Syu. If the msys2-runtime package is updated, close the shell and run msys2_shell.bat.

MSYS2 the Easy Way

The easiest way to build KiCad using the MSYS2 build environment is to use the KiCad PKGBUILD provided by the MSYS2 project to build package using the head of the KiCad development branch. To build the KiCad package, run the msys2_shell.bat file located in the MSYS2 install path and run the following commands:

pacman -S git
mkdir src
cd src
git clone https://github.com/Alexpux/MINGW-packages
cd MinGW-packages/mingw-w64-kicad-git
makepkg-mingw -is

This will download and install all of the build dependencies, clone the KiCad source mirror from GitHub, create both 32-bit and 64-bit KiCad packages depending on your MSYS setup, and install the newly built KiCad packages. Please note that this build process takes a very long time to build even on a fast system.

MSYS2 the Hard Way

If you do not want to create KiCad packages and prefer the traditional make && make install method of building KiCad, your task is significantly more involved. For 64 bit builds run the mingw64_shell.bat file located in the MSYS2 install path. At the command prompt run the the following commands:

pacman -S mingw-w64-x86_64-cmake \
          mingw-w64-x86_64-doxygen \
          mingw-w64-x86_64-gcc \
          mingw-w64-x86_64-python2 \
          mingw-w64-x86_64-pkg-config \
          mingw-w64-x86_64-swig \
          mingw-w64-x86_64-boost \
          mingw-w64-x86_64-cairo \
          mingw-w64-x86_64-glew \
          mingw-w64-x86_64-curl \
          mingw-w64-x86_64-wxPython \
          mingw-w64-x86_64-wxWidgets \
          mingw-w64-x86_64-toolchain \
          mingw-w64-x86_64-glm
cd kicad-source
mkdir -p build/release
mkdir build/debug               # Optional for debug build.
cd build/release
cmake -DCMAKE_BUILD_TYPE=Release \
      -G "MSYS Makefiles" \
      -DCMAKE_PREFIX_PATH=/mingw64 \
      -DCMAKE_INSTALL_PREFIX=/mingw64 \
      -DDEFAULT_INSTALL_PATH=/mingw64 \
      -DKICAD_SCRIPTING=ON \
      -DKICAD_SCRIPTING_MODULES=ON \
      -DKICAD_SCRIPTING_WXPYTHON=ON \
      ../../
make install

For 32-bit builds, run mingw32_shell.bat and change x86_64 to i686 in the package names and change the paths in the cmake configuration from /mingw64 to /mingw32.

Known MSYS2 Build Issues

There are some known issues that are specific to MSYS2. This section provides a list of the currently known issues when building KiCad using MSYS2.

64-bit Package of Boost 1.59

The context library of the x86_64 package of Boost version 1.59 is broken and will cause KiCad to crash. You must downgrade to version 1.57 by running the command:

pacman -U /var/cache/pacman/pkg/mingw-w64-x86_64-boost-1.57.0-4-any.pkg.tar.xz

If the file mingw-w64-x86_64-boost-1.57.0-4-any.pkg.tar.xz is no longer in your pacman cache, you will have to down load it from the MSYS2 64-bit SourceForge repo. You should also configure pacman to prevent upgrading the 64-bit Boost package by adding:

IgnorePkg = mingw-w64-x86_64-boost

to your /etc/pacman.conf file.

Building KiCad on OSX

Building on OSX is challenging at best. It typically requires building dependency libraries that require patching in order to work correctly. For more information on the complexities of building KiCad on OSX, see the OSX bundle build scripts.

Download the wxPython source and build using the following commands:

cd path-to-wxwidgets-src
patch -p0 < path-to-kicad-src/patches/wxwidgets-3.0.0_macosx.patch
patch -p0 < path-to-kicad-src/wxwidgets-3.0.0_macosx_bug_15908.patch

Known Issues

There are some known issues that effect all platforms. This section provides a list of the currently known issues when building KiCad on any platform.

Boost C++ Library Issues

As of version 5 of GNU GCC, using the default configuration of downloading, patching, and building of Boost 1.54 will cause the KiCad build to fail. Therefore a newer version of Boost must be used to build KiCad. If your system has Boost 1.56 or greater installed, you job is straight forward. If your system does not have Boost 1.56 or greater installed, you will have to download and build Boost from source. If you are building Boost on windows using MinGW you will have to apply the Boost patches in the KiCad source patches folder.
