Hi All,
This might be a dummy question, but it has been puzzling me for some
time. So if someone could give me some explanation, that would be really
appreciated.
In bitbake.conf, we have:
ALLOW_EMPTY_${PN}-dev = "1"
ALLOW_EMPTY_${PN}-dbg = "1"
That means we allow emtpy -dev/-dbg packages. But what are the benefits
of these empty -dev/-dbg packages?
In some cases it's useful to satisfy default dependcencies:
bitbake.conf:RDEPENDS_${PN}-staticdev = "${PN}-dev (= ${EXTENDPKGV})"
and -dev needs ${PN} even when it's empty in some recipes where all
files are split into separate packages
bitbake.conf:RDEPENDS_${PN}-dev = "${PN} (= ${EXTENDPKGV})"
Not sure about -dbg one.
Hi Martin,
Thanks for your explanation.
If I understand it right, the above two RDEPENDS are the default for
most recipes and are expected to be overridden in some special recipes,
right? For example, if a recipe is separated into several packages, it's
possible that we need to override the RDEPENDS_${PN}-dev.
Here's another question. If a -dev package is empty, does the default
RDEPENDS on "${PN}" still make sense?
Best Regards,
Chen Qi
