This page is intended for cases where the process at OpenSCAD_User_Manual/Building_on_Linux/UNIX has failed for some reason. Please file an issue on OpenSCAD's github if the above process did not work for you. In the meantime, these instructions might provide a workaround solution for you.

  • If your system already has an outdated binary CGAL package installed (such as libcgal-dev) you best remove it with something like 'apt-get purge libcgal-dev'.
  • If you custom-compiled BOOST, set the BOOST_ROOT environment variable to the installation location.
  • Download CGAL from [1] . Try to get the latest version.
  • CGAL requires boost, cmake, mpfr, and gmp to all be installed. The process at OpenSCAD_User_Manual/Building_on_Linux/UNIX can help you install them. On Debian/Ubuntu, it the command to install the necessary components looks something like this:
sudo apt-get install libboost-dev cmake libmpfr-dev libgmp3-dev
  • Extract
tar -xf CGAL-*tar*
  • Build
cd CGAL-$version
cmake . -DCMAKE_INSTALL_PREFIX=$HOME/openscad_deps
make
sudo make install
  • Note that some older systems, like NetBSD5, wont compile CGAL - either because CGAL wasn't ported to work with them or their compiler is too old or other reasons.
