Installing PCRaster

Installing binaries

PCRaster is available on conda-forge and can be installed using conda. Supported platforms are Linux, macOS and Windows.

We recommend to download and install Miniconda. The user guide and short reference on conda can be found here. After install you can check which Python versions are supported by PCRaster:

conda search -c conda-forge pcraster

Afterwards you can create a new environment and install PCRaster, e.g. with:

conda create --name pcraster37 python=3.7 -c conda-forge

conda activate pcraster37

conda install -c conda-forge pcraster

You can also combine these steps and install additional packages in one go e.g. by:

conda create --name pcraster37 -c conda-forge python=3.7 pcraster spyder matplotlib

Modifying PATH and PYTHONPATH environment variables as required for previous PCRaster versions is not necessary anymore, this is done automatically when you activate your environment. If you installed previous versions of PCRaster you need to remove their entries from the PATH and PYTHONPATH environment variables before activating your environment.

Always use the conda-forge channel when installing further packages into your PCRaster environment.

Compiling from source


The following build instructions apply to PCRaster version 4.3 (or later). You don’t want to build earlier versions yourself. Really, you don’t.


Building PCRaster depends on various software tools, development packages and libraries, at least:

  • Compiler supporting C11 and C++17 (gcc 7 or higher)

  • CMake >=3.14

  • git

  • Python > 3.5

  • Boost > 1.66

  • NumPy

  • GDAL >= 2.0

  • Qt > 5.7

  • XercesC 3.2

You will need to build libraries yourself in case they are not available on your system or those versions are too old.

Obtaining the sources

Preferably you should use a versioned software release to build PCRaster. This is recommended in case you want to use PCRaster in production. You can obtain a source package as follows:

$ # sha256: 2772ae0dc228cebaf1891623526a097799ab7fe212c606f6d2fe6c3c47b70be6
$ wget

It is also possible to obtain the PCRaster sources from our code repository, e.g. in case you want to test the latest developments:

$ mkdir pcraster_build
$ cd pcraster_build
$ git clone --recursive

Configuring and building

CMake requires an out of source build. Make sure that you check and adapt the install location and Python version:

$ mkdir build
$ cd build

$ cmake -G"Unix Makefiles" ../pcraster -DCMAKE_INSTALL_PREFIX=$HOME/pcraster-4.3.0 -DPython3_EXECUTABLE:FILEPATH=/usr/bin/python3.7

In case some of the 3rd party libraries are not installed in default locations, you need to provide hints before you call CMake. For example, on CentOS 7 you may need to use:

$ export BOOST_INCLUDEDIR=/usr/include/boost169/
$ export BOOST_LIBRARYDIR=/usr/lib64/boost169/
$ export GDAL_ROOT=/tmp/gdal-2.4.1
$ export Qt5_DIR=/tmp/qt5.12.4

# CMake command as above
$ cmake -G"Unix Makefiles" ....

Before you build check the CMake output to ensure that correct library versions are used.

After a successful configure run, build and install PCRaster:

$ cmake --build . --target all -- -j$NR_CPUS
$ cmake --build . --target install


After a successful build you will need to add $HOME/pcraster-4.3.0/bin to your PATH environment variable and $HOME/pcraster-4.3.0/python to your PYTHONPATH environment variable to run the PCRaster applications.

Build options

Some build options can be changed. In the build directory type:

$ ccmake .

Toggle and browse to the PCRASTER entries. Modify entries with great care.
