What is the correct way to get a list of package run-time dependencies during the build process?

What is the correct way to get a list of package run-time dependencies during the build process?

Hi,

 

I noticed that during the build bitbake supplies you rather correct (if it
is correct in the recipe) list of recipe build-time dependencies. However,
this isn't true for run-time dependencies. Moreover it seems that when you
define a recipe you don't have to list run-time dependencies, but rather
than package manager would figure it out. 

 

But is there a way to get this info from bitbake during the build? 

 

Best Regards,
Elena.

After do_package has run the dependencies will be correct, but until that
point the runtime library dependencies won't have been extracted.

Oh, this is a great advice. Thank you Ross! This would save me another headache :)

Actually my task seems to run after do_package has already run, but I don’t have RDEPENDS filled with anything useful. How you supposed to query them from bitbake? I was trying these variants: 

 

recipe.r_deps = d.getVar('RDEPENDS_' +  <http://recipe.name> recipe.name, True)

 

or even simple:

 

recipe.r_deps = d.getVar('RDEPENDS’, True)

Elena.

Did you mean RDEPENDS_ + package name?

I have it like this: 

 

recipe.name = d.getVar('PN', True)

recipe.r_deps = d.getVar('RDEPENDS_' +  <http://recipe.name> recipe.name, True)

Elena.

So I wasn't quite right - I think you also need to come after
do_packagedata and also you'll need to read the subpackage metadata.
Inspired by insane.bbclass, this works:

addtask printrdeps before do_build after do_package do_packagedata
do_printrdeps[nostamp] = "1"
python do_printrdeps() {
    bb.build.exec_func("read_subpackage_metadata", d)
    for p in d.getVar("PACKAGES", True).split():
        bb.warn("Got package %s" % p)
        bb.warn("Got RDEPENDS %s" % d.getVar("RDEPENDS_" + p, True))
}

Yes, this actually works. Thank you very much Ross!
