сравнить ABI файлов ELF в программных пакетах (compare ABIs of ELF files in software packages)
Окружение (Environment)
abipkgdiff loads two default suppression specifications files,
merges their content and use it to filter out ABI change reports
that might be considered as false positives to users.
• Default system-wide suppression specification file
It's located by the optional environment variable
LIBABIGAIL_DEFAULT_SYSTEM_SUPPRESSION_FILE. If that
environment variable is not set, then abipkgdiff tries to load
the suppression file
$libdir/libabigail/libabigail-default.abignore. If that file
is not present, then no default system-wide suppression
specification file is loaded.
• Default user suppression specification file.
It's located by the optional environment
LIBABIGAIL_DEFAULT_USER_SUPPRESSION_FILE. If that environment
variable is not set, then abipkgdiff tries to load the
suppression file $HOME/.abignore. If that file is not present,
then no default user suppression specification is loaded.
In addition to those default suppression specification files,
abipkgdiff will also look inside the packages being compared and
if it sees a file that ends with the extension .abignore, then it
will consider it as a suppression specification and it will
combine it to the default suppression specification that might be
already loaded.
The user might as well use the --suppressions option (that is
documented further below) to provide a suppression specification.
