Not that I know of.
Wouldn't $^0 and $Config{archname} cover quite a few, though?
No. As previously explained, these values reflect what was true when and
where perl was compiled. In general, I need what is true at the time
buildfarm is run.
Anyway, I think we have some good possibilities.

in perl:
use POSIX;
print join(',',POSIX::uname()),"\n";
prints:
Windows NT,hostname.domain.com,5.0,Build 2195 (Service Pack 4),x86
Works on all Platforms.
(more detail on Win with: use Win32; join(' ', Win32::GetOSVersion()),
"\n";)

If you can open a command shell you can get the OS version with the
'ver' command under Windows:
C:\>ver
Microsoft Windows XP [Version 5.1.2600]
C:\>
This should work on 2000 or later. (Windows 2000 is 5.0.something.)

Hmm. The osname and archname might still be useful, but the rest could
be out of date.

On UNIX systems uname may work pretty well. But I guess each system may
have slightly different options. What'll probably happen is that you
end up with a big if() statement testing $Config{osname} wtih each case
having specific code to determine the specifics. But for that you need
information. How do you get the currently running release of windows
for example?
Have a nice day,

Re: [HACKERS] automatic system info tool?
I'm fairly familiar with it :-)
The trouble is that it gives info set at the time perl was compiled,
which doesn't help with the problem where a machine has been upgraded.
For example, on this FC3 machine it reports a different kernel version
from the one I have upgraded to, not surprisingly.
So what I need if possible is a runtime tool to detect the info we need.

It would seem to be a lot easier to use the values from perl itself,
given you're already using it:
# perl -MConfig -e 'print "os=$Config{osname}, osvers=$Config{osvers},
archname=$Config{archname}\n"'
os=linux, osvers=2.6.15.4, archname=i486-linux-gnu-thread-multi
If you look at perl -V it give you a subset of useful values, probably
a lot nicer than munging config.guess. It'll even tell you the size of
of the C datatypes if you're interested :)
