I have been trying to install linphone 3.7.0 on Slackware -current 64 bit, using packages from slackbuilds, for version 14.1 of Slackware.
I have met with interminable demands for dependacies from SlackBuilds scritps.
What should I be doing and is there a pre-built version of linphone ?

No, there is no pre-built linphone package for Slackware-current. As a reminder slackbuilds.org doesn't provides pre-built packages nor SlackBuilds intended for and tested in Slackware-current. However if you do find issues trying, it would be nice to report them to the maintainer.

You can use sbopkg and "sqg -p linphone"[1] to make a build queue, but there is no guarantee of course.

Also, in my opinion if you don't intend to test Slackware-current to help find and solve its issues before the next release, there is no point running it anyway.

[1]FWIW here is the output of that command for Slackware version 14.1:

Thanks , I will try sbopkg and report when it produces results. Searches indicate that I am not the only one having problems with SIP phones on Linux.

Have you tried jitsi?

At the moment, I started a topic here aimed at getting SBo packages updated and retuned for the next pending release of Slackware through -Current. Right now we are discussing build issues, bugs, and crashes in the topic, so do report it there so it can be investigated properly.

As Didier said SBo isn't aimed at -Current for obvious reasons, but keeping bugs and build issues in check while -Current is evolving, does make the next release cycle smoother with more packages readily available at release time.

I have tried sbopkg and it does not seem to work with my setup. Which is basicly slackware64 -current with some packages from other distros.

What do you mean it doesn't work? slackbuilds.org doesn't maintain builds for Slackware-current, but generally, most 14.1 programs will compile on -current, and the ones that don't, usually only need minor modification.

Are you getting errors?

what I'm getting is, sbopkg not fetching dependancies for linphone. It fetches linphone itself ok. However what I want is to have the dependancies feched as well. Presumably, I need to use a named que to do this. How do I do it ? The documentation that I have read on it is a bit cagey as to the use of ques/dependancies.

Look in the /usr/doc/sbopkg-0.37.0/contrib/ directory for the sqg script.

I am reading sqg at the moment, but very slowly.

Having read sqg I have a new question:-

Can sqg work recursively to find dependancies of dependancies, or am I using a naughty word now ?

It will work fine. Just run sqg -p linphone (I have movied (or maybe symlinked, I can't remember) sqg to /usr/bin, although, it should probably reside in /usr/sbin) and it should create all the needed dependencies for linphone. This includes dependencies of dependencies. Then, you can either run the "GUI" (ncurses) portion of sbopkg and then look for linphone under the Queues menu. If you want to do it from the command line, run sbopkg -i linphone and then when it prompts you, select the queue option.
