stackoverflow(Why so many symbolic links?). Bing(linux dynamic linker/loader).

After installation of Opencv 2.4.9, I found it created many symbolic links.

libopencv_core.so -> libopencv_core.so.2.4
libopencv_core.so.2.4 -> libopencv_core.so.2.4.9

so=shared object. ...so.2.4 (soname ) and ...so.2.4.9 (real name) files allow you to update libraries and still support programs needing older ones. libopencv_core.so (linker name) is only for the linker. For -lopencv_core, gcc prefixes a lib and postfixes a .so to the library name.
