This shell script downloads, configures, builds, and installs deal.II with common dependencies on linux-based systems.

The following commands download the current version of the installer and then installs the latest deal.II release and common dependencies:

 git clone https://github.com/dealii/candi
 cd candi
 ./candi.sh -j2

Follow the instructions on the screen (you can abort the process by pressing < CTRL > + C)

  module load mpi/openmpi-`uname -i`
  export CC=mpicc; export CXX=mpicxx; export FC=mpif90; export FF=mpif77
  ./candi.sh

  export CC=mpicc; export CXX=mpicxx; export FC=mpif90; export FF=mpif77
  ./candi.sh

  export CC=mpicc, export CXX=mpicxx; export FC=mpif90; export FF=mpif77
  ./candi.sh --platform=./deal.II-toolchain/platforms/supported/linux_cluster.platform

Note that you probably also want to change the prefix path (see below) and the path to BLAS and LAPACK in the configuration file (see below).

You can get a list of all options by running ./candi.sh -h

You can combine the command line options given below.

  ./candi.sh --prefix=Your/Prefix/Path

  ./candi.sh -j <N>

• Example: to use 2 build processes type ./candi.sh -j2.
• Be careful with this option! You need to have enough system memory (e.g. at least 8GB for 2 or more processes).

Edit the configuration file behind the file "candi.cfg", e.g.

  gedit candi.cfg

You can adapt several things to your personal needs here

• the DOWNLOAD_PATH folder (can be safely removed after installation),
• the UNPACK_PATH folder of the downloaded packages (can be safely removed after installation),
• the BUILD_PATH folder (can be safely removed after installation),
• the INSTALL_PATH destination folder,

and more options.
