C:R:A allows a developer to describe the interface version and compatibility detailsfor their library. The soname and filename of the eventual library is an implementation detail that depends how *library* versions work on theparticular OS you build on -- and will be different on Linux vs Windows vsAIX vs HPUX etc Cheers, Gary -- ())_.

According paragraph 6.3 of http://www.gnu.org/software/libtool/manual.html, Interfaces and library versions progress as follow: C R A Major,Minor,Micro Action-------------------------------------------------------------------------------------------------------- 0 0 0 0 0 0 Initial version 1 0 1 0 1 0 Adding an interface 2 0 2 0 2 0 Adding another interface 2 1 2 0 2 1 Modifying code only 2 2 2 0 2 2 Modifying code only 3 0 3 0 3 0 Adding another interface 3 1 3 0 3 1 Modifying code only 4 0 3 1 3 0 Changing an interface 5 0 3 2 3 0 Changing another interface 6 0 0 6 0 0 Removing an interface
OK for first 7 lines but Changing an interface modifies library version from 0.3.1 to 1.3.0 and removing an interface modifies library version from 2.3.0 to 6.0.0 Aren't library versions increasing a little too fast ?
