Requirements

It is assumed that you already have a development environment setup which can build packages. Other than that all that is required is the package libabigail. 

$ sudo yum install libabigail
(or as root)
# yum install libabigail

Procedure

The abipkgdiff program compares the ABIs of ELF binaries contained in two versions of a given package P. Let's call P1.rpm and P2.rpm the former and later version of packageP. Please note that abipkgdiff needs the debug information packages of P1 and P2 in order to operate. Let's call these debug info packages P1-debuginfo.rpm and P2-debuginfo.rpm You need to have them available locally, just as you do for P1.rpm and P2.rpm

Comparing

To compare the ABIs of P1 and P2 here is the command line: 

abipkgdiff --d1 P1-debuginfo.rpm --d2 P2-debuginfo.rpm P1.rpm P2.rpm

A report with details of the ABI changes is emitted on the standard output of the command line.
