# This is _NOT_ the library release version, it's an API version. # Please read Chapter 6 "Library interface versions" of the libtool # documentation before making any modification # # http://sources.redhat.com/autobook/autobook/autobook_91.html # # The version scheme used by Libtool tracks interfaces, where an interface # is the set of exported entry points into the library. All Libtool libraries # start with `-version-info' set to `0:0:0' -- this will be the default # version number if you don't explicitly set it on the Libtool link command # line. The meaning of these numbers (from left to right) is as follows: # # current # The number of the current interface exported by the library. A current # value of `0', means that you are calling the interface exported by this # library interface 0. # # revision # The implementation number of the most recent interface exported by this # library. In this case, a revision value of `0' means that this is the # first implementation of the interface. # # If the next release of this library exports the same interface, but has # a different implementation (perhaps some bugs have been fixed), the # revision number will be higher, but current number will be the same. # In that case, when given a choice, the library with the highest revision # will always be used by the runtime loader. # # age # The number of previous additional interfaces supported by this library. # If age were `2', then this library can be linked into executables which # were built with a release of this library that exported the current # interface number, current, or any of the previous two interfaces. # # By definition age must be less than or equal to current. At the outset, # only the first ever interface is implemented, so age can only be `0'. # # 1. If you have changed any of the sources for this library, the revision # number must be incremented. # This is a new revision of the current interface. # # 2. If the interface has changed, then current must be incremented, and # revision reset to `0'. # This is the first revision of a new interface. # # 3. If the new interface is a superset of the previous interface (that is, # if the previous interface has not been broken by the changes in this # new release), then age must be incremented. # This release is backwards compatible with the previous release. # # 4. If the new interface has removed elements with respect to the previous # interface, then you have broken backward compatibility and age must be # reset to `0'. # This release has a new, but backwards incompatible interface. # # For example, if the next release of the library included some new commands # for an existing socket protocol, you would use -version-info 1:0:1. # This is the first revision of a new interface. This release is backwards # compatible with the previous release. # # Later, you implement a faster way of handling part of the algorithm at the # core of the library, and release it with -version-info 1:1:1. This is a new # revision of the current interface. # # Unfortunately the speed of your new implementation can only be fully # exploited by changing the API to access the structures at a lower level, # which breaks compatibility with the previous interface, so you release it # as -version-info 2:0:0. This release has a new, but backwards incompatible # interface.
