  • the root OpenSceneGraph directory will be referred to as [OSG_ROOT] by this wiki

Setup OpenSceneGraph Build System

In Terminal:

  1. cd [OSG_FOLDER]
  2. mkdir build
  3. mkdir install
  4. cd build
  5. cmake ..
  6. ccmake . or cmake-gui
    • ccmake is a Terminal based cmake interface that displays information in a textual based interface
    • CMAKE_INSTALL_PREFIX = [OSG_FOLDER]/install
    • (Optional) BUILD_OSG_EXAMPLES = ON
    • press [t] to toggle advanced mode
    • certify that OPENGL_INCLUDE_DIR, OPENGL_gl_LIBRARY, and OPENGL_glu_LIBRARY were found as a result of freeglut install
    • press [c] to configure
    • press [g] to generate

Build OpenSceneGraph

In Terminal:

  1. cd [OSG_FOLDER]/build if you aren't already there
  2. make or make -j <NUMBER_OF_CORES> if you know the number of cores your computer has
  3. sudo make install to install the compiled OpenSceneGraph into the [OSG_FOLDER]/install folder
  4. Confirm that the osgversion executable is in [OSG_FOLDER]/install/bin

Test OpenSceneGraph

In Terminal:

  1. Add the following to your .bashrc login file
export OSG_ROOT=[OSG_FOLDER]/install
export PATH=$PATH:$OSG_ROOT/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OSG_ROOT/lib
  1. source ~/.bashrc
  2. Run osgversion in the Terminal, it should tell you the version of OpenSceneGraph that you have installed

Congratulations, OpenSceneGraph is now built and installed; ready for use with OpenFrames!
