Smarts sm_perl uses Perl 5.8.8, which is distributed with Smarts 9.2. All the Perl scripts provided with Smarts (including sm_getinfo.pl) will work with Linux 6.4.
So, running sm_getinfo.pl using sm_perl in a Linux 6.4 installation will complete successfully.
From a Smarts installation, you can run "sm_perl -version" to see the Perl version used by your Smarts environment. Under the Perl 5.8.8 libs, the following libraries/modules are packaged with Smarts 9.2 products:
use strict;
use Carp qw(croak carp);
use Cwd;
use Archive::Tar;
use Archive::Tar::Streamed;
use Getopt::Long;
use Digest::MD5;
use Time::localtime;
use English qw( -no_match_vars );
use File::Find;
use File::Basename;
use POSIX qw[ _exit ];
These libraries/modules are used in sm_getinfo.pl which was tested on Linux, Solaris and Windows platforms, and so works using the Perl 5.8.8 version distributed with Smarts 9.2 products.
