[Slackbuilds-users] Linphone sources and dependencies

[Sebastian Arcus]

I have just taken over Linphone maintenance and trying to update the SBo 
scripts for the current version. What I have done so far:

1. I have followed the instructions and cloned the repo on a Slackware 
-current (because of cmake minimum version - see below):

$ git clone https://gitlab.linphone.org/BC/public/linphone-desktop.git 
--recursive

This downloads 3.0GB of files on my computer in a directory called 
linphone-desktop. A large chunk of this is in a dir called linphone-sdk. 
Leaving aside for a minute the huge size of the archive, I can follow 
through with the instructions and manually build and compile Linphone.


2. However, if I just download version 5.0.0 directly from git (later 
versions require cmake 3.2.2) on either Slackware -current or 15.0:

$ wget 
https://gitlab.linphone.org/BC/public/linphone-desktop/-/archive/5.0.0/linphone-desktop-5.0.0.tar.gz

This downloads a 3MB file, without the sdk. Now if I try to follow the 
instructions and compile this, I get:

-- No plugins found for the application to build

My question is - does that mean the only way to compile Linphone is:

1. To download a 3GB archive (which I'm still not sure why is so large) 
of 5.0.0 - so that it compiles on Slackware 15.0? or

2. To somehow install separately linphone-sdk - maybe having to create a 
separate SBo package for it? or

3. Pass somehow on the command line the address of the git repository 
for it - but this will presumably again result in a large download?


I'm a bit out of my depth here, so if anyone could provide some hints 
where to look next, that would be much appreciated
