Installation

Dependencies

• CMake (version ≥ 3.16)¹.

• A Fortran compiler.

Instructions

1. Download Jumble.

2. Unzip it:

   unzip Jumble-master.zip
   

3. Decide in which directory you want to install Jumble and type the command below with your choice after -DCMAKE_INSTALL_PREFIX= (enter an absolute path). For example:

   cmake -B build -S Jumble-master -DCMAKE_INSTALL_PREFIX=~/.local
   

   The command above is the configuration command. It will create a directory named build.

4. Compile:

   cmake --build build
   

5. Install:

   cmake --install build
   

You do not need to keep the downloaded directory Jumble-master nor the build directory after installation.

Advanced instructions

• You can choose any name and any location for the build directory:

  cmake -B /wherever/any/name -S Jumble-master -DCMAKE_INSTALL_PREFIX=~/.local
  

• Optionally, in the configuration command, you can change the precision for real numbers of procedures zroots_unity, outersum, cumprod, outerdiv and vabs. By default, the precision for real numbers in Jumble is set to be the default kind of the real type of the Fortran compiler you will use. You can change the value for the procedures listed above to any real kind you want. For example:

  cmake -B build -S Jumble-master -DJumble_CPP_WP='kind(0d0)'
  

  or you could choose selected_real_kind(10) for example, etc.
