PFLARE Spack External Repository

This repository provides a Spack package for PFLARE (https://github.com/PFLAREProject/PFLARE), including optional support for Python bindings via Cython and PETSc4Py.

Usage:

1. Clone this repo

2. Add this repo to Spack:

   spack repo add PFLARE_spack

3. Install PFLARE:

   spack install pflare

   PFLARE depends on PETSc, so the build configuration will follow the PETSc options you choose. For example, to build a static version of PETSc (and hence PFLARE), set the shared library variant for PETSc to false:

   spack install pflare ^petsc~shared

   or for example, to build PETSc (and hence PFLARE) with 64 bit integers:

   spack install pflare ^petsc+int64

4. After installation, you can set up your environment (e.g., LD_LIBRARY_PATH, etc.) using:

   spack load pflare

Optional Python variant

1. To build PFLARE with Python bindings (via Cython and PETSc4Py):

   spack install pflare+python

   or the test flag can be added to check that the Python bindings are built during the install:

   spack install --test=root pflare+python

2. After installation, you can set up your environment (including PYTHONPATH) using:

   spack load pflare+python
