I've never used it, but I'd certainly be interested in reading that if
you ever write it up. :)
I use a directory, abicompare in the home of my build user followed by
the library name then a version folder, i.e.:
~/abicompare/OpenImageIO/1.0.11
and
~/abicompare/OpenImageIO/1.0.13
Then I use a little scripe I wrote[1] to unpack the main library and
devel rpms into the version directory of each library because I can
never remember how to do it manually:
# cd ~/abicompare/OpenImageIO/1.0.11
# rpmunpack /path/to/rpms
(repeat for second version)
# abi-compliance-cheker -l OpenImageIO -dump 1.0.11/
(repeat for second version, the version as a directory works nicely
because it will assume that's the version of the library so no need to
specify the version manually)
# abi-compliance-checker -l OpenImageIO -old /path/to/abidump-1.0.11
-new /path/to/abidump-1.0.13
Works like a charm as long as there's not any bad headers (like
windows only headers) installed. If that happens I usually just have
to rm the offending headers till I get a good dump.
Audrey,
How would this process change using abi-dump instead?
The ABI dump should be created in the different way. Use "abi-dumper
1.0.11/usr/lib/libopenImageio.so -o /path/to/abidump-1.0.11 -lver
1.0.11" command instead of "abi-compliance-cheker -l OpenImageIO -dump
1.0.11/" to create the ABI dump. Note that the library should be
compiled with debug info, so you should extract and compare appropriate
debug-info rpm packages instead of release ones. Otherwise the tool will
report "can't find debug info in object(s)".
All of these steps are automated in the pkgdiff 1.6. Just compare
debug-info rpm packages by this tool: pkgdiff --details
libA-v1-debuginfo.rpm libA-v2-debuginfo.rpm, and see the output html report.
