## HDF5

```{code-block} toml
:emphasize-lines: 2
name = "my_science_app"
dependencies.hdf5 = "*"
```

HDF5 is supported for Fortran, C and C++ languages. The `pkg-config` backend is employed by `fpm` to find a valid local HDF5 installation, so, please insure that `pkg-config` is also available when using this metapackage.

Both the default and the high-level (`HL`) interfaces are linked against if available.
- On Ubuntu, special steps are taken to ensure `HL` are added.
- On Ubuntu with oneAPI compilers, `CMake` HDF5 installations are supported (`apt` versions only support `gfortran`).

:::{note}
Codes using HDF5 built with `oneAPI` compilers should not have the `-standard-semantics` flag: it changes module name mangling from `_mp_` to `_MP_` which makes HDF5 modules unavailable.
