LibrePCB is a free EDA suite to develop printed circuit boards on Windows, Linux and MacOS. More information and screenshots are available at librepcb.org.

Official stable releases are provided at our download page.

Please read our user manual to see how you can install and use LibrePCB. The quickstart tutorial provides a step-by-step guide through the whole process of designing a PCB.

Contributions are welcome! See librepcb.org/contribute and CONTRIBUTING.md for details.

For internal details take a look at the developers documentation.

WARNING: The master branch always contains the latest UNSTABLE version of LibrePCB. Everything you do with this unstable version could break your workspace, libraries or projects, so you should not use it productively! For productive use, please install an official release as described in the user manual. For development, please read details here.

To compile and run LibrePCB, you need the following software components:

• Compiler: g++, MinGW or Clang (any version with C++20 support should work)
• Qt >= 6.2 (make sure the imageformats plugin is installed too as it will be needed at runtime!).
• OpenCASCADE OCCT or OCE (optional, OCCT highly preferred)
• OpenGL Utility Library GLU (optional)
• zlib
• OpenSSL
• CMake 3.16 or newer

Instead of installing the dependencies manually on your system (see instructions below), you can also use one of our Docker images with all dependencies pre-installed (except GUI tools like QtCreator). These images are actually used for CI, but are also useful to build LibrePCB locally.

sudo apt-get install build-essential git cmake openssl zlib1g zlib1g-dev \
     qt6-base-dev qt6-tools-dev qt6-tools-dev-tools qt6-l10n-tools \
     libqt6core5compat6-dev qt6-declarative-dev libqt6opengl6-dev libqt6svg6-dev \
     qt6-image-formats-plugins libglu1-mesa-dev libtbb-dev libxi-dev \
     occt-misc libocct-*-dev
sudo apt-get install qtcreator # optional

sudo apt-get install build-essential git cmake openssl zlib1g zlib1g-dev \
     qt5-default qtdeclarative5-dev qttools5-dev-tools qttools5-dev \
     qtquickcontrols2-5-dev libqt5opengl5-dev libqt5svg5-dev \
     qt5-image-formats-plugins libglu1-mesa-dev liboce-*-dev
sudo apt-get install qt5-doc qtcreator # optional

sudo pacman -S base-devel git cmake openssl zlib desktop-file-utils shared-mime-info \
     qt6-base qt6-5compat qt6-declarative qt6-svg qt6-tools qt6-imageformats opencascade
sudo pacman -S qt6-doc qtcreator # optional

Note: Instead of installing the dependencies and building LibrePCB manually, you could install the package librepcb-git from the AUR. The package clones and builds the latest version of the master branch from GitHub.

1. Install Xcode through the app store and start it at least once (for the license)
2. Install homebrew (the package manager)
3. Install dependencies: brew update && brew install qt6 cmake opencascade
4. Make the toolchain available: brew unlink qt && brew link --force qt6

Download and run the Qt for Windows installer from here. LibrePCB does not compile with MSVC, so you must install following components with the Qt installer:

• MinGW 11.2.0 64-bit compiler
• Qt binaries for MinGW 11.2.0 64-bit (use the latest 6.x version)
• Qt 5 Compatibility Module for MinGW 11.2.0 64-bit
• Qt Image Formats for MinGW 11.2.0 64-bit
• CMake

For the OpenCascade library the installation procedure is not that easy unfortunately. Basically you have to build it by yourself, see instructions here. However, to avoid this effort you could instead just set the CMake option USE_OPENCASCADE=0 (can be set in the QtCreator build config) to allow compiling LibrePCB without OpenCascade.

It's important to clone the repository recursively to get all submodules too:

git clone --recursive https://github.com/LibrePCB/LibrePCB.git && cd LibrePCB

When updating the repository, make sure to also update all the submodules recursively. Otherwise you may get strange compilation errors:

git submodule update --init --recursive

You can either build LibrePCB using Qt Creator, or you can build on the command line using cmake. To build LibrePCB using cmake/make:

mkdir build && cd build
cmake ..
make -j8

The binary can then be found in build/apps/librepcb/.
