missing .la files

Toutatis · 01-20-2018, 05:14 AM

Hello,

I have tried to compile vlc from git (version 3.0-rc7), on slackware64-current, and got errors complaining about missing .la files (for libva-drm, libva-x11 and libva). I created basic ones (containing only the names of the libraries), and compilation was successful (I had also to disable wayland). vlc seems to work correctly.
My question is : why some libraries have no .la files ?
Is there an automatic way to create the most basic ones ?

Slackware tries to avoid installing .la files where possible. You should not require their use anyway.
I built vlc-3.0.0.rc6 yesterday and that went just fine (on the other hand, I have spent quite some time during the last couple of months to modify my vlc.SlackBuild so that it builds vlc3 with all its new dependencies instead of vlc2).

you most probably have some vlc dependencies that you have built in the past that used those *.la files before they got removed: you should rebuild also all of vlc's dependencies, and dependencies of dependencies, and so on...

I have no libraries depending on the old version of libva, and I have checked all .la or .pc files for the presence of these libva*.la . They are present only in the vlc/plugins directories.
How is it possible to see that something depends on them ?

Not entirely on topic, but the default behavior of slibtool from the midipix devs installs no .la files at all. The downside is that its not as compatible as GNU's libtool yet and I suspect that is largely because of how many people ended up relying on libtool's buggy behavior...
