I have a library that I must install, for not being widely available and to ease packaging in my own .deb package. The file is a .so file and I will set the RUNPATH for it to find some other dependency.
Where should I put my private installed library? It is an architecture independent file that is read-only, but I could not find anywhere a conclusion on where to store that file exactly. Given that PREFIX=/usr, where should I put it?
The file should go in a private directory in lib/. I deduced this from looking at http://www.pathname.com/fhs/pub/fhs-2.3.html and lintian was warning me to not put any arch-specific file in /usr/share.
So the correct place to place private files is /usr/lib/mypackagename.
