Arch Linux

Greetings :o)

Please, if this is not a problem with gdal 2.1.2-2, then kindly refer me to whatever package you may think is the problem :o)

qmapshack 1.8.1-2, which depends on gdal, worked before the latest upgrade of gdal.
Note that the package (hdf5 1.10.0_patch1-2) providing the libhdf5.so* library files, was _not_ upgraded, and that the latest officially stable version of hdf5 contains the older libhdf5.so.100 .

pacman -Syyu does not solve the problem.
Upgrading hdf5 to the newer version in testing does not solve the problem, but, rather amusingly, then complains that libhdf5.so.100 (the old version) could not be found ;o)
Downgrading gdal to the previous version does not solve the problem, but seems to require downgrading of other packages too. I'm not keen to start working my way through an entire tree of downgrades :o)
Other suggestions kindly welcomed :o)

The problem
-----------
[johnny@comp ~]$ qmapshack
qmapshack: error while loading shared libraries: libhdf5.so.101: cannot open shared object file: No such file or directory
