Hi, I am getting involved with https://github.com/libyui , the UI library powering YaST. The basic design is a core library, libyui, which provides the API but has no actual UI. One of the 3 backends, libyui-{ncurses,gtk,qt}, is needed. I am looking for examples of best practices of versioning the shared libraries and setting up the dependencies among the parts of the framework. Current problems of libyui in this area: - not being careful about the so-versioning. That is a solved problem for a single(!) library, see https://github.com/openSUSE/libzypp/blob/a01b41c7dfe42a1fae9d9431fbad61997fb... - the user-facing ABI of libyui and the backend-facing ABI are not well separated. Is there any project which has figured this out? - expressing the dependency "the core lib needs at least one backend with a matching ABI" is done via the yui_backend symbol but that breaks bootstrapping the build (See Fedora 19 on https://build.opensuse.org/project/monitor/devel:libraries:libyui ) Can you point me to any projects that handle this situation (common api + backends), however well? -- Martin Vidner, Cloud & Systems Management Team http://en.opensuse.org/User:Mvidner Kuracke oddeleni v restauraci je jako fekalni oddeleni v bazenu
