dune-gdt-super is a git supermodule which serves as a demonstration and testing module for dune-gdt. This module provides the correct versions of all relevant DUNE modules and external libraries as git submodules.

In order to build everything, do the following:

• Initialize all submodules:

  git submodule update --init --recursive
  

• Take a look at config.opts/ and find settings and a compiler which suits your system, e.g. config.opts/gcc-debug. Select one of those options by defining

  export OPTS=gcc-debug
  

  If you have the ninja generator installed we recommend to make use of it by selecting OPTS=gcc-debug.ninja, which usually speeds up builds significantly.

• Call

  ./local/bin/gen_path.py
  

  to generate a file PATH.sh which defines a local build environment. From now on you should source this file whenever you plan to work on this project, e.g.:

  source PATH.sh
  

• Download and build all external libraries by calling (this might take some time):

  ./local/bin/download_external_libraries.py
  ./local/bin/build_external_libraries.py
  

• Build all DUNE modules using cmake and the selected options (this will take some time):

  ./dune-common/bin/dunecontrol --opts=config.opts/$OPTS --builddir=$PWD/build-$OPTS all
  

  This creates a directory corresponding to the selected options (e.g. build-gcc-debug) which contains a subfolder for each DUNE module. See the dune/gdt/test subfolder for tests, e.g.,

  build-gcc-debug/dune-gdt/dune/gdt/test/
