OpenSpace has been tested on Ubuntu versions 18.04 and 20.04.

Developer Tools

Install the following tools:

  • Git 2.7+
  • GCC 9+
  • CMake 3.12+


You can install gcc-9 using the following commands. At the time of this writing, gcc-9 is not the default version in ubuntu 18.04 (but is default in 20.04), so this involves some additional steps. The final commands configure ubuntu’s “update-alternatives”, which allows a user to select among multiple installations of gcc:

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade && sudo apt-get autoclean && sudo apt-get autoremove

reboot in case there are kernel changes

sudo apt-get install build-essential software-properties-common
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-9 g++-9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-9
sudo update-alternatives --config gcc

If you don’t want to install GCC 9 globally, you can overwrite the CMake options instead:


If you do want to change the defaults: here

The CMake CXX flags variable should be set to: -DGLM_ENABLE_EXPERIMENTAL

It is recommended to create a new CMake string variable OPENGL_GL_PREFERENCE and set its value to GLVND.


Install the following libraries:

* The recommended image library for Linux. While FreeImage seems to work well with OpenSpace on other platforms, problems have been encountered while using this on Linux

sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install -y \
build-essential software-properties-common \
gcc-9 g++-9 cmake \
glew-utils freeglut3-dev libsoil1 \
libxrandr-dev libxinerama-dev xorg-dev libcurl4-openssl-dev libgdal-dev libxcursor-dev \

Note that a Qt5 installation is currently required (see general compile page). CMake will need help finding this install (for example, the required Qt5_DIR entry may be something like: /opt/Qt/5.15.0/gcc_64/lib/cmake/Qt5). In the future, this will be updated with the libQt5*.so files which can be installed via apt-get.

Compile OpenSpace

1) Checkout 1) Configure 1) Make


git clone --recursive "$openSpaceHome"

mkdir -p "$openSpaceHome/build"
cd "$openSpaceHome/build" || exit

cmake \


CMake step

This can be one of the following:

  • cmake .. The simplest way if there are no CMake issues to resolve or build options to set.
  • ccmake .. A curses pseudo-gui version of CMake (run sudo apt install cmake-curses-gui if not installed).
  • cmake-gui .. A Qt GUI version of CMake.

With any of these methods, CMake is first configured, then (if no errors) the generate step creates the build files.

The Web GUI interface does not work with the linux version of OpenSpace. Use the F1 menu instead, which provides full functionality but has a different layout.

Run OpenSpace




Make sure that you are using the correct version of gcc/g++

  • Double check CMAKE_CXX_COMPILER and /usr/bin/c++ --version to be sure. It should be at least 8.0

Error: could not read symbols: Missing DSO from command line

  • Try using g++ instead of gcc.

Error: GLSL 3.00 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.00 ES, and 3.00 ES

  • Enter the following line in the terminal before running, or add this to ~/.bashrc or ~/.profile: export MESA_GL_VERSION_OVERRIDE=4.3

It may be necessary to install boost if trying to build some of the older branches.
