# `nektar-env` image

This image is designed to provide a build environment for Nektar++ based on the
Debian 12 (bookworm) build image. It installs all libraries to enable Nektar++
to be compiled with most/all third-party dependencies turned on. In particular
we install the following development libraries:

- Boost
- TinyXML
- LAPACK/BLAS
- OpenMPI (enables `NEKTAR_USE_MPI`)
- FFTW (enables `NEKTAR_USE_FFT`)
- Python (enables `NEKTAR_BUILD_PYTHON`)
- HDF5 (enables `NEKTAR_USE_HDF5`)
- OCE, Triangle and TetGen (enables `NEKTAR_USE_MESHGEN`)
- PETSc (enables `NEKTAR_USE_PETSC`)
- ARPACK (enables `NEKTAR_USE_ARPACK`)
