Francesco, You can do
spack spec dealii%clang to see what spack will install. You can then check which package requires OpenGL (it is not deal.II) and then remove support for this package if you don't need it. For instance, let's say that it's trilinos that's pulling OpenGL and you don't need it, you can do spack install dealii%clang~trilinos Best, Bruno -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
