VectorLinux 7.0 CORE ALPHA 1

[stretchedthin]

One more request. Included Cmake is version 2.6.2. Latest version is 2.8.1.  Would be nice to have the newer version.
Cheers.

I was reading Headachers very helpful tutorial on Jack audio concerning realtime privileges and it left me with a question.

In that thread he mentioned the need for a 

-2.6 series kernel with realtime-lsm patch.

.  Does the plan for VL7.0 include a realtime-lsm patch?  It would make for a much better base for those wishing to explore Jack-audio and the applications which use it.

To be honest don't know my experience with jack and pulse audio has been bad to say the least. If anyone has found a reasonable installation that works consistently on a a slack based system keep me up to date. So far been a headache for me. Something for you guys to explore................however.

Will this version include support for USB3?

[bigpaws]

Prince,

That is from kernel development not Vector.

There has been USB 3 support in the kernel starting around Sept. 2009.

Please add some Intel graphic support, Especialy Intel 845g support. Thnkx

I think part of the problem is that Slackware does not use PAM as it's method for authenticating user privileges.  It may be worth some discussion between the Vectorlinux developers whether you want to follow suite.  Here's how Jack uses PAM...

How should I configure my Linux 2.6 Operating System?
Real-time scheduling

JACK requires real-time scheduling privileges for reliable, dropout-free operation. The server requests these privileges when running with the -R option.

Most recent distributions use PAM to manage the permissions of users on a relatively granular level. If the file /etc/security/limits.conf exists on your system, it is using PAM. In order to configure PAM such that normal users can run jackd with realtime privileges make sure the following lines exist:

@audio   -  rtprio     99
@audio   -  memlock    unlimited

This /etc/security/limits.conf file of course don't exist in Vectorlinux, but Headacher suggests another way....
If the kernel can be patched with http://sourceforge.net/projects/realtime-lsm/,
then simply by making jack part of the audio group it will gain realtime privileges.

So I think either PAM, or Realtime Linux Security Module would be a good first step (for Jack anyway don't know about pulse audio).

Yeah, I've ran into the same wall, not with jack, but with other things. Every other distro uses PAM or at least if it doesn't use it, offers the libraries, Slack doesn't nor does VL.

This should really be addressed

[prince]

Thanks, Moe.

I guess that means the Vl7 is using the latest 2.6.3*... kernel.

The PAM thing his nothing to do with kernel version, it has been a problem in slack for a long time. Its the reason you can't build a gdm version newer than 2.20 on slackware or VL

Figuring VLC is a good stress test, I tried the latest version (1.1.0).
The long list of dependencies seemed to build okay, but when it came down to VLC itself, error:

Code: [Select]

/usr/lib/gcc/i586-vector-linux/4.3.3/../../../../i586-vector-linux/bin/ld: cannot find -lpng12

I've ran into the same error a couple times. The latest for me was in the building of synfig studio.  Also couldn't build audacity yet, but not sure if it's the same error but do believe it is lipng14 related.

I don't think the error is coming from the vlc build itself, but one of the dependencies that is created along with the build.

/usr/lib/gcc/i586-vector-linux/4.3.3/../../../../i586-vector-linux/bin/ld: cannot find -lpng12

This is coming from a dep lib for the program which I may not have caught libmng comes to mind. Anyway ldd your executable look at the libs it uses and check /var/adm/packages see if the dep has a i486 extension that is somehow related to graphics/gui then you will prolly have to rebuild that against the libpng14. Its kind of a hunt and peck but if you guys could help me this would be appreciated.

Thanks,
Vec

Nightflier what dependencies does your script try to build??  I can compare your list to the items I've built and installed here on my box.  Reason being is I've got vlc working.
I just ran a build of vlc-1.1.0 by itself. No depedencies were built within the slackbuild, just vlc. I was hoping to see where it failed, I didn't even check the dependency list, just took a chance that I had them already.  I can compare your list against what I've built and see if any of them used a patch or had to be rebuilt against libpng14.

My mistake, Moe, that response was to bigpaws's answer.

As far as the PAM thing is concerned, I am aware it has nothing to do with the kernel, thanks.

As far as the USB 3.0 support, I was looking for the Linux Kernal number.

Ok, to all:

The Linux Kernel 2.6.31 number is the number that first supported USB 3.0. That's the answer I was looking for.

The  VectorLinux 7.0 CORE ALPHA 1 release info didn't mention which Kernel is being utilized, but that's

OK.   The answer could be discreet for security reasons.  As long as it support USB 3.0 for my latest AMD build,
that's fine with me.
