I have a build using an the system HDF5 (older), it is producing the following error on the dashboard:
[https://open.cdash.org/viewBuildError.php?buildid=5491099](https://open.cdash.org/viewBuildError.php?buildid=5491099)

If you cannot update the system’s version, we could _#ifdef_ the call to `setLibverBounds` based on version.

Looks like setLibverBounds was added in 1.8.15:
[https://support.hdfgroup.org/HDF5/doc/ADGuide/Changes\_1\_8\_x.html](https://support.hdfgroup.org/HDF5/doc/ADGuide/Changes_1_8_x.html)
Probably good to ifdef like this, as I also had to do in libminc:
```auto
#if (H5_VERS_MAJOR==1)&&(H5_VERS_MINOR<10)
fapl.setLibverBounds(H5F_LIBVER_V18, H5F_LIBVER_V18);
#endif
```

Man did HDF5 drop the ball on versioning…
We have a further problem, the H5F\_LIBVER\_V18 feature wasn’t added until 1.10.2, so, 1.10.0 and 1.10.1 don’t have a backwards compatibility setting.
See history at the bottom of this page:

Alternatively… we could restrict the API, as seen in H5version.sh:
```auto
defined(H5_USE_18_API_DEFAULT) && !defined(H5_USE_18_API)
#define H5_USE_18_API 1
#endif /* H5_USE_18_API_DEFAULT && !H5_USE_18_API */

Is this for ITK 4.x or ITK 5.x? If it is for ITK 5.x then can’t we just say that HDF5 1.10.2 is the minimum version required?

We are probably not taking advantage of the new stuff introduced, and being backwards compatible is an advantage.
