How to Build

Building Sourcetrail requires several dependencies to be in place on your machine. However, our CMake based setup allows to disable indexing support for specific languages which reduces the number of dependencies to a minimum.

Building the bare minimum

Required Tools


This is required for generating the Sourcetrail version number. Get it from:

Make sure git is available in added to your PATH environment variable.

CMake v3.12

This is used for generating a build configuration. Get it from:

Additional tools for Windows

Visual Studio

Additional tools for Unix


This is optionally used to speed up rebuilds if found in PATH.

Required dependencies

Boost 1.67

For the msvc compiler pre-built binaries can be downloaded from

For building on Unix:

$ ./ --with-libraries=filesystem,program_options,system,date_time
$ ./b2 --link=static --variant=release --threading=multi --runtime-link=static --cxxflags=-fPIC

Qt 5.12

Note: still causes style issues on Windows, resort to Qt 5.10

For the msvc compiler pre-built binaries can be downloaded from


For Windows / Visual Studio

$ cd Sourcetrail
$ mkdir -p build/win64
$ cd build/win64
$ cmake -G "Visual Studio 15 2017 Win64" -DBOOST_ROOT=<path/to/boost_1_68_0> -DQt5_DIR=<path/to/Qt/version/platform/compiler/lib/cmake/Qt5> ../..

If you are using the gui, we recommend that you activate advanced mode. Also you may be required to add some of the defines via the "Add Entry" button.

After generating the build configuration, just open the Sourcetrail.sln file that was generated by CMake and build the Sourcetrail project.

For Unix

$ cd Sourcetrail
$ mkdir -p build/Release
$ cd build/Release
$ cmake -DCMAKE_BUILD_TYPE="Release" -DBOOST_ROOT=<path/to/boost_1_68_0> -DQt5_DIR=<path/to/Qt/version/platform/compiler/lib/cmake/Qt5> ../..
$ make Sourcetrail


Run Sourcetrail from within the build directory. During execution Sourcetrail needs resources from bin/app/data and bin/app/user. Cmake creates symlinks to these directories within the build directory.

Enable C/C++ Language Support

Required dependencies

LLVM/Clang 9.0.0


For the msvc compiler, follow these steps to build the project. Make sure to check out the correct tag and to run the cmake command exactly as described.


For Unix, follow this installation guide



Run CMake with these additional options:


Enable Java Language Support

Required dependencies

JDK 1.8

Install JDK and make sure the JAVA_HOME environment variable is set:


Also make sure <jdk_root>/bin is available in your PATH environmen variable.


Run CMake with these additional options:


Enable Python Language Support

Required dependencies

WinRAR (for Windows only)


Run CMake with these additional options:




Required Tools

Visual Studio
Wix 3.11
Wix extension for Visual Studio

Make sure to append these directories to your PATH environment variable:

  • VisualStudio/Common7/Tools
  • VisualStudio/Common7/IDE
  • .../Microsoft SDKs/Windows/v7.1A/Bin (for uuidgen in deploy script)
  • .../WiX Toolset v3.11/bin
  • .../WinRAR

Run ./script/ script which will generate 32bit/64bit builds and packages these into a portable .zip file and a Wix-based Windows installer, each.


After building, run the script within the build directory which will create a bundle and generate a Sourcetrail_<version>.dmg container.


Run ./script/ package

How to Run the Tests

The automated test suite of Sourcetrail is powered by Catch2. To run the tests, simply execute the Sourcetrail_test binary. Before executing, please make sure to set the working directory to ./bin/test.
