Hi
Since new update/upgrade I am unable, with debian amd64 stretch, to preload
a library that lies on the same folder from which I am working. What has
changed in amd64 stretch that does no more finds the library and looks
elsewhere for a non-existing library? Commands below:

Therefore, I am unable, at this point, to launch a program for remote
visualization (which worked well before the said update/upgrade):

Grateful for advice
