HDF5 does not build on macOS Monterey with GCC 11.2 #1157
Description
I want to build HDF5 1.10.7 with GCC 11.2 on macOS Monterey. This used
to work fine on the previous version of macOS. It currently fails
because the autodetection of the Fortran kind variables fails. I tried
HDF5 1.10.6 and 1.12.1 as well, with the same result.
I found that the problem is that the output file is not closed by the
Fortran program that is run at configuration time. The enclosed patch
corrects the issue by adding respective "close" statements that are
present in all other, similar Fortran programs.
