From 84024e245f346cdf1da955cea4ab4c2c0a0886b2 Mon Sep 17 00:00:00 2001 From: Paul Spooren Date: Thu, 20 Aug 2020 15:44:51 -1000 Subject: [PATCH] build: add whatdepends target to imagebuilder The package manager `opkg` offers the function `whatdepends` to print packages that depend on a specific package. This feature is useful when used in a CI to not only build an upgraded package but all packages with a dependency. Usage: make whatdepends PACKAGE=libipset The resulting list can be fed into a SDK building all packages and warn if anything fails.
