makefile - Makefile 中 DEPENDS 的确切作用是什么？

Question

这是我的 Makefile 的示例。

define Package/luci-app-myapp
   SECTION:=luci
   CATEGORY:=LuCI
   SUBMENU:=3. Applications
   TITLE:=GUI for myapp package
   PKGARCH:=all
   DEPENDS:=+myapp
endef

这个 Makefile 中 DEPENDS 的确切作用是什么？哪些元素可以成为 DEPENDS 的值？

Answer 1

DEPENDS is basically a variable. In openwrt this variable is used to define dependency between the packages. Detailed use of this variable is documented in openwrt link
