Hello,

I try to install vlc on Slackware 14.2.
After taking the build on http://www.slackware.com/~alien/slackbuilds/, I run it and install vlc. When I launch it then, an vlc icon is getting on the dock below, but it won't open (and nothing happens if I click on it).
I had some dependance problem (I guess) to install it : I had to pre-install (with sbopkg) : meson, ninja and lua.
The build and installation processes were done well, I don't get any errors. So I don't understand what could be the problem. Any ideas?

Thank you.

what happens if you try to run it from the command line?

Well, it kind of work actually!

But I get some mistakes in the Terminal; and I have no tools : I haven't the usual toolbar at the top (with "File Preferences ..."), or the advancement bar at the bottom.

Here is a part of what I got :

try a different movie.

Same result...

you could uninstall that one and try the precomplied one he has.

I downloaded the .txz file and installed it with installpkg.
I get the same result as before when I launch it from the command line, I can't launch it through the graphic interface.

For the installation, I downloaded only vlc-3.0.6-x86_64-1alien.txz : maybe I need other files like npapi-vlc-20190112-x86_64-1alien.txz?

yeah, sorry I forgot there is a few more for 3.0

Problem solved, thank you!

So, I followed the steps on the website (https://alien.slackbook.org/blog/finally-vlc-3/) : I first installed libwacom, libinput (and the dependencies), then libxkcommon, qt5 and qt5-webkit. After that, I reinstalled vlc with installpkg. It works now perfectly!
