hdf5-18 @1.8.16 Cannot use environment variable HDF5_ROOT_DIR

[fredericperez1@…]

Due to the switch to hdf5 @1.10.0, my software crashes (this hdf5 version has some bugs).

The port hdf5-18 @1.8.16 fixes the problem, but moves all the dependencies to /opt/local/include/hdf5-18/ and /opt/local/lib/hdf5-18/. It turns out that a few programs use the environment variable HDF5_ROOT_DIR, which here points to /opt/local. It is used to point the compiler to $HDF5_ROOT_DIR/include and $HDF5_ROOT_DIR/lib.

Of course, this does not work anymore because this would mean changing all my makefiles to $HDF5_ROOT_DIR/include/hdf5-18 and $HDF5_ROOT_DIR/lib/hdf5-18. This is not portable, thus I cannot make use anymore of this environment variable.

I believe it would make more sense to have the hdf5-18 include and lib directories inside another single directory such as /opt/local/hdf5-18/, but I am not sure this is very good practice. In any case, the current implementation does not look workable for me.

Thanks

In the future, please Cc the port maintainers (port info --maintainers hdf5-18), if any. Note that a "request" ticket type is only for requesting a new port.

Moving hdf5-18 to a completely separate install prefix would also help address #51923. Perhaps /opt/local/libexec/hdf5-18/ or /opt/local/lib/hdf5-18/ is a reasonable prefix?

Done in r150946. The new prefix or $HDF5_ROOT_DIR is ${prefix}/local/lib/hdf5-18.
