Shared library versions and naming (cont.)

Linker name

• Format: libname.so
  
  
• Purpose: allows us to construct version-independent link commands which automatically operate with the right (i.e. most up to date) version of the shared library.
  
  
• Created as a symbolic link to either real name or soname of most recent major version of the library.
  
  
• More convenient to have it point to soname. Why?
  
  
• Examples:

  libdemo.so           -> libdemo.so.2
  libreadline.so       -> libreadline.so.4
