There's two objectives involved in this scheme, which it's helpful to keep in mind: 1. Binaries already installed on the system should not break when a library is upgraded. Hence, if the new library would cause an older binary to crash, then it does not take over the SONAME of the old one. 2. Binaries already installed on the system should, where possible, benefit from bug fixes when a library is upgraded. A binary linked against an old SONAME will continue using the old buggier library, until somebody remembers to rebuild it. Hence, SONAME changes should be as infrequent as possible. (Where critical, vendors can and often do backport bug fixes to older versions while retaining the ABI) _______________________________________________ fluid-dev mailing list fluid-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/fluid-dev
