There exist different ways of naming share libraries. What you describe above is one way of doing so. I prefer using the "libtool way" (cf. info libtool versioning), i.e. libXXX.so -> libXXX.so.X (SONAME) -> libXXX.so.X.Y.Z This is the way the vast majority of shared libs are versioned on Linux. > However it should be noticed that library versioning is so hairy and > unproperly undocumented that 90% of developers invariably get it wrong the > first time and also later. The reason is simple: There is no "nominal standard". There exist several ways of versioning shared libraries, all with pros and cons. There exist different personal preferences, mostly stemming from a person's and a package's history. > So they often need education.

ROTFL - Inventor is an elderly, former "monster package" SGI had sold for $$$$ during the 1990's and had released LGPL'ed ca. in 2000. They had been responsive to patches/fixes in subsequent years, but since ca. 2003 their responsiveness has stalled. In other words, this is "dead-stable" code without an active upstream nor development. De facto, everything is in "keep-alive" maintenance by Linux distros keeping their packages going and them occasionally mutually harvesting/exchanging their patches and modifications. I.e. the de facto upstream are Debian and Fedora (i.e. me). The 0.0.0 in this particular case originates from Debian, because the original sources from SGI did not apply any SONAME.
