looking over some bbrecipes such as vlc.inc or mesa.inc they have a part that says PACKAGES =+ ""

eg:

PACKAGES =+ "libvlc"

or

PACKAGES =+ "libegl-mesa libegl-mesa-dev .."

but these packages are unavailable to bitbake or IMAGE_INSTALL="" they complain Nothing PROVIDES ...

so how does someone add just libvlc or just libegl-mesa. without installing the entire recipe.

The question "how to install a package without installing the entire recipe" does not make sense as you don't install recipes. The recipe must be in a layer that's available to bitbake though.

A recipe describes how to build one or more packages out of specified sources. The packages are defined by PACKAGES variable (which contains some sensible default packages but often recipes add some more). bitbake works on recipes not packages, so when you tell bitbake to build a recipe, all of its packages will be built.

If you want one of the built packages to be installed into an image, IMAGE_INSTALL_append = " packagename" should work (note the whitespace inside quotes). Typically you wouldn't need to do this for libraries like in your examples though: the application that uses the library should runtime depend on it instead.

If you have a specific problem, maybe putting that into the question would help.

  • i am looking to install just libvlc on a headless build. what i am facing is vlc recipe will not build without x11 no matter what i change in a bbappend. as well as i just need libgl-mesa-dev. i tried even making my own layer meta-vlc-nox but that too also fails – Bbbh Nov 18 '15 at 13:02
  • Well, that's a completely different question, and I'd recommend you to start a new quesiton for that. You'd also have to show us what you've done in order to try to build vlc without x11. – Anders Nov 20 '15 at 07:11
