Building MFIX-Exa with gmake

============================



If you want to use gmake to build MFIX_Exa, you will need to

clone amrex and AMReX-Hydro into a local directories, and also

clone mfix:



.. code:: shell



    > git clone https://github.com/AMReX-Codes/amrex.git

    > git clone https://github.com/AMReX-Codes/AMReX-Hydro.git

    > git clone http://mfix.netl.doe.gov/gitlab/exa/mfix.git

    > cd mfix/exec



Then, edit the GNUmakefile (or set an environment variable)

to define AMREX_HOME and AMREX_HYDRO_HOME

to be the path to the directories where you have put amrex

and AMReX-Hydro.  Note that the default locations of

AMREX_HOME and AMREX_HYDRO_HOME are in the subprojects directory,

which is where a cmake configuration may clone these repositories.

Other options that you can set include

.. note::

   **Do not set both USE_OMP and USE_CUDA/HIP/DPCPP to true.**



Then type



.. code:: shell



    > make -j



An executable will appear; the executable name will reflect

some of the build options above.
