The ABI Compliance Checker (ACC) can help analyse the ABI and report incompatible changes but doesn't cover every situation AFAIK. The libtool manual has a bunch of useful information about maintaining shared libraries. http://ispras.linuxbase.org/index.php/ABI_compliance_checker https://www.gnu.org/software/libtool/manual/libtool.html For the Debian side of library packaging, maint-guide covers the very basics, debian-policy covers requirements and the (quite outdated, possibly still useful) libpkg-guide covers library packaging generally. https://www.debian.org/doc/manuals/maint-guide/advanced.en.html#library https://www.debian.org/doc/debian-policy/ch-sharedlibs.html http://www.netfort.gr.jp/~dancer/column/libpkg-guide/libpkg-guide.html Two things I would like to highlight in particular: Debian likes library upstreams who set their default symbol visibility to hidden and then whitelist their public symbols. Debian likes library upstreams who implement symbol versioning. -- bye, pabs http://bonedaddy.net/pabs3/
