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 Base Application

Required Tools

• CMake v3.20 (required for Windows, Linux and MacOS)

  • Reason: Used to generate a build configuration for your build system
  • Download: https://cmake.org/download

• Git (required for Windows, Linux and MacOS)

  • Reason: Used for version control and to automatically generate the Sourcetrail version number from commits and tags
  • Download: https://git-scm.com/download
  • Remarks: Make sure git is added to your PATH environment variable before running CMake

• Visual Studio (required for Windows)

  • Reason: Used for building Sourcetrail
  • Download: https://visualstudio.microsoft.com/downloads/

• ccache (optional for Linux and MacOS)

  • Reason: Used to speed up rebuilds if found in PATH
  • Download: https://ccache.dev/download.html

Required dependencies

• Boost 1.74

  • Reason: Used for file system access and interprocess communication
  • Prebuilt Download for Windows: https://sourceforge.net/projects/boost/files/boost-binaries/
  • Building for Unix:

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

• Qt 5.15

  • Reason: Used for rendering the GUI and for starting additional (indexer) processes.
  • Prebuilt Download: http://download.qt.io/official_releases/qt/

Building

On Windows Faced some problems with Conan2 and Windows

• To set up your build environment run:

  $ pip install conan
  $ git clone --recurse-submodules https://github.com/OpenSourceSourceTrail/Sourcetrail.git
  $ cd Sourcetrail
  $ conan install . -s build_type=Release -of .conan/vc/ -b missing
  $ cmake --preset=vc_release
  $ cd ../build/Release/
  $ ninja
  

On Unix

• To set up your build environment run:

  $ pip install conan
  $ git clone  --recurse-submodules https://github.com/OpenSourceSourceTrail/Sourcetrail.git
  $ cd Sourcetrail
  $ conan install . -s build_type=Release -of .conan/gcc/ -b missing -pr:a .conan/gcc/profile
  $ cmake --preset=gnu_release
  $ cd ../build/Release/GNU
  $ ninja
  

Running

• Run Sourcetrail from within the build directory. During execution Sourcetrail needs resources from bin/app/data and bin/app/user. CMake creates symlinks within the build directory that make these directories accessible.

Enable C/C++ Language Support

Required dependencies

• LLVM/Clang 15.0.7
  • Reason: Used for running the preprocessor on the indexed source code, building and traversing an Abstract Syntax Tree and generating error messages.
  • Building: Make sure to check out the correct tag: git checkout llvmorg-15.0.7
  • Building for Windows: Follow these steps to build the project. Run the cmake command exactly as described. Make sure to build with -DLLVM_ENABLE_PROJECTS:STRING=clang -DLLVM_ENABLE_RTTI:BOOL=ON -DLLVM_TARGETS_TO_BUILD=host.
  • Building for Unix: Follow this installation guide to build the project. Make sure to build with -DLLVM_ENABLE_PROJECTS:STRING=clang -DLLVM_ENABLE_RTTI:BOOL=ON -DCLANG_LINK_CLANG_DYLIB:BOOL=ON -DLLVM_LINK_LLVM_DYLIB:BOOL=ON -DLLVM_TARGETS_TO_BUILD=host.

Building

• Run CMake with these additional options:

  -DClang_DIR=<path/to/llvm_build>/lib/cmake/clang
  -DBUILD_CXX_LANGUAGE_PACKAGE=ON
  

• Build Sourcetrail as described above.
