[Buildroot] gst-plugins-base alsa dependency

[Phil Edworthy]

Hi,

 

A lot of the GStreamer plugins are built or not based on whether other
packages are on the target. For example, gst-plugins-base only builds the
alsa plugins if it can find alsa-lib. A clean build means these plugins
aren't built due to the build order. However, if I rebuild gst-plugins-base
afterwards, they are built.

 

How can a Buildroot package be told of build order dependencies, without
requiring the packages to be included?

 

Thanks

Phil

By doing something like:

ifeq ($(BR2_PACKAGE_ON_WHICH_I_DEPEND),y)
MYPKG_DEPENDENCIES += package-on-which-i-depend
endif

If the package "package-on-which-i-depend" is enabled in the
configuration, then you will have the guarantee that it gets compiled
before the current package.

Thanks Thomas, that's a nice and simple way to fix it.

Thanks, I've just committed a patch that does this to git.
