Public bug reported: ---Problem Description---
[Ubuntu 22.04] smc_run does not work, libsmc-preload.so cannot be preloaded =========================================================================== The reason for this is that the aforementioned shared object is installed under: /usr/lib64/libsmc-preload.so Which is AFAICT not what we want, because AFAIU it violates the Debian Policy Manual (https://www.debian.org/doc/debian-policy/ch- opersys.html#s-fhs), and ld.so in Ubuntu has a default search path that understandably does not cover /usr/lib64. Interestingly the upstream Make file does try to detect if we are run on Ubuntu, and choose the install path accordingly. Hereby it relies on "lsb_release -si" returning "Ubuntu", which may or may not be a good idea -- I don't know. In any case if the upstream Makefile does not suit Ubuntu/Debian, then the packager is ought to patch it. Thus in my opinion this is a packaging problem.
