For this purpose, the option -DPYTHON_EXECUTABLE=/path/to/python_exec must be used to point to the desired Python installation. PyROOT can be built with only one version of Python even if multiple installations are present in the system. Similarly, Python2_EXECUTABLE and/or Python3_EXECUTABLE can be used to point to particular Python executables. In order to build with specific Python installations (not necessarily the highest ones) hints to CMake can be provided by using -DPython2_ROOT_DIR=python2_dir and/or -DPython3_ROOT_DIR=python3_dir to point to the root directory of some desired Python installation.

To build PyROOT, it is thus suggested to verify that python-dev is present and install it if not. Moreover, for a given Python installation to be considered, it must provide both the Python interpreter (binary) and the development package. If only one version can be found, PyROOT will be built only for that version.
If no option is specified, PyROOT will be built for the most recent Python3 and Python2 versions that CMake can find. The following pure Python modules will appear as well: 3.8, 2.7, etc.) the following libraries will appear both in the build directory and in the installation directory: For each Python version X.Y used to build PyROOT (e.g. In this case, PyROOT libraries are built by default with both Python3 and Python2. In the following, build and installation processes both with CMake >= 3.14 and = 3.14 The main feature introduced in v6.22 concerning the PyROOT build system is the possibility to build for both Python3 and Python2 (MultiPython), available only if the version of CMake used to build is >= 3.14. In the following the main aspects are summarized for both after and before v6.22.
PyROOT, the set of Python bindings of ROOT, changed its structure and build/installation process in v6.22. Must be compiled with the same C++ standard with which ROOT was compiled.Īlso note that compatibility with compilers shipped with devtoolsets on CentOS or Red Hat is not guaranteed.
bin/thisroot.bat # also available for PowerShell: thisroot.ps1Īs it makes use of a C++ interpreter, ROOT has somewhat stricter requirements than other C++ libraries: applications that depend on ROOT Proceed to use IDE project files or start the build from the build directory, after CMake has finished running: You can force CMake to use a given build tool, see the Usage section. In this case make sure that the toolset that you intend to use is the only one reachable from the shell and that the shell itself is the correct one for you development environment. This can fail if CMake cannot detect your toolset, or if it thinks that the environment is not sane enough. See the Build Options and Variables sections for fine-tuning your build. CMake will use default values for all build parameters.

G"Visual Studio 17 2022" is the generator (here Visual Studio 2022), -A Win32 is for the architecture (here 32 bit), so replace -A Win32 with -A 圆4 to build in 64 bit mode, and -Thost=圆4 is to use the native 圆4 toolset (to increase the available memory for the builds).ĬMake will detect your development environment, perform a series of test and generate the files required for building ROOT.

On Windows, open a Native Tools Command Prompt for vs 2022.ĭownload and unpack the ROOT sources for a specific release (make sure to download the “Source distribution” and not a binary distribution) or simply clone ROOT’s git repository and check out the branch you would like to build, for example:Ĭmake -G "Visual Studio 17 2022" -A Win32 -Thost = 圆4 -DCMAKE_INSTALL_PREFIX = We will use the command-line, non-interactive CMake interface. The following are the basic instructions for UNIX-like systems and Windows. Make sure you have installed all required dependencies before building ROOT.
If you already have experience with CMake, this is the recommended starting point. The Options and the Variables section is a reference for customizing your build. If you are a CMake novice, start on Basic CMake usage and then go back to the If you are really anxious about getting a functional ROOT build, go to the Quick Start section. Your build tool (GNU make, Ninja, Visual Studio, etc) for building ROOT. ROOT uses the CMake cross-platform build-generator tool as theĬMake does not build the project, it generates the files needed by Fixed Location Installation (gnuinstall=ON).Location Independent Installation (gnuinstall=OFF).Enabling experimental features, aka ROOT7.
