[QT4] Acces to OS Version # for Linux?

Is there an equivalent to QSysInfo for Linux?
Seems odd that only Mac and Windows are defined in this class.
TIA

If there was, how would you propose it worked?

The same as QSysInfo. Is this a trick question?

Yes, it was. I meant, what do you propose your system would return
as a Linux version? The kernel number? "SUSE 9.3"? What does the
phrase "Linux version" mean?

Linux _is_ the kernel, so it can only return the version number of the
kernel. If it returns anything like SuSE 9.3 or Debian 3.1, this would
be a distribution name/version, not the Linux version.

But Linux isn't the OS. Does the SysInfo return the kernel32.dll or
ntoskrnl.exe version? I don't think so ;)

I don't want to start a Flame here or something, but "Linux" actually
is the OS. Of course for having something usable you'll need some tools
like a shell and cp and such things. But I do _not_ consider SuSE 9.3 an
Operating System, its much more.
If at all QSysInfo should return something Like
<kernel-version> running on <distribution-name> <distribution-version>
But then, I don't know QSysInfo and the format it returns...

Well, no. Linux is the kernel. The combination of kernel and
distribution packages would be called an OS.

Well, no :-) At least I consider it a bit different. I do agree that Linux
is the kernel. But SuSE is by far more than just an Operating System.
Also consider LFS, where there is no distribution - where is the OS
there? Normally I would consider the kernel+shell+tools like cp/mv to
belong to the Operating System. Anything else is "extra" Software.
But that's my opinion and I'm not going to write any more comments on
this..

No. :)
Linux is "just" the kernel.
The OS is not Linux, but GNU/Linux; Linux kernel + GNU (supporting
libraries, shell, basic tools) = OS.
OS + additional apps = distribution.
Hope I cleared it up. :)

Well, I said nothing wrong, according to you. I only left a part out...
> Linux is "just" the kernel.
ACK.

Ack. I did not realize that yet (at least not really), which is a shame,
as I'm running:
andreas@morpheus:~>uname -a
Linux morpheus.apaku.dnsalias.org 2.6.12.4-cherry+radeon #1 Wed Aug 17 12:30:45 CEST 2005 i686 GNU/Linux
:-(
> OS + additional apps = distribution.
Full ACK.

When I use QSysInfo in Windows, I get an enumerated representation of the OS
Version that tells me what release of Windows the application is running
under.
The application I'm writing is required to run on Windows XP SP2 or later.
Any earlier version and the application puts up and error and quits.
The application is also required to run under Macintosh 10.3 or newer.
Anything earlier and you can guess what the application does.
The application is also required to run under RedHat 3 or newer. So I'd
really like to know a) is the program running under RedHat linux and b) is
the release 3.0 or newer.
Is there a way to get access to this information under the linux release of
QT 4.0.1?

The concept works for Mac and Windows because the releases are
centralized and distributed by a single entity.
But my point is that obtaining an "OS version" for Linux doesn't
really work because there are lots of kernels, distributions, and
packages - so there's no conventional way of noting what OS version
is being used. By writing your application for RedHat 3 or newer,
you would be precluding a large portion of people who would be
running other Linux distributions or Unices.

can't you launch the shell command "uname" and read its output?

You might be able to. Its not a given that its there on all Unix machines, noe
that it uses the same format, or the same args. AFAIK.
