Hi, I'd like to introduce shlib-compat -- an ABI compatibility checker for shared libraries with symbol versioning. The idea of such tool was discussed on mail lists before.
shlib-compat uses debugging info (dwarf) from compiled library to compare definitions of exported symbols, i.e. no sources is necessary. Code quality is pre-alpha, loops in struct/union definitions are not handled properly, values for enums and const/volatile are ignored. Reporting is not yet implemented, it has knob to dump complete symbol definitions in json which is rather useless. It just prints if symbol definitions match. shlib-compat parses libc.so.7 on my system (amd64), but there is a lot warnings about symbols it can't find in dwarf dump (looks like these are implemented in asm). Sources contain several trivial test cases. devel/dwarfdump port is required (as well as objdump which is in base). Source code available on github: http://github.com/glk/shlib-compat Or as tarball: http://github.com/downloads/glk/shlib-compat/shlib-compat-0.1.tar.gz I don't have much free time to continue developing it right now, but feel free to add a ticket on github, submit a patch or fork it. Thanks, Gleb. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[email protected]"
