problem about package and subpackage

Hi,


I wanted to add dhcp(4.2.0) into my image. And I added "dhcp" into IMAGE_INSTALL of my image's bb file. After I runing bitbake, the dhcp package is normally fetched and compiled and so on. But during do_rootfs bitbake reported as follow:
Processing dhcp...
Unable to find package dhcp (dhcp)!
ERROR: Function 'do_rootfs' failed


I note that in /meta/recipes-connectivity/dhcp/dhcp4.inc the dhcp package is split into 4 subpackages(PACKAGES += "dhcp-server dhcp-client dhcp-relay dhcp-omshell"). Now If I remove "dhcp" from IMAGE_INSTALL and add these 4 subpackages' name into IMAGE_INSTALL and run bitbake AGAIN, they can be normally added into my final image.


I've tried to modify last part of dhcp4.inc as follow: But bitbake still reported "Unable to find package dhcp"
FILES_${PN} = ""
FILES_${PN} += "${sbindir}/dhcpd ${sysconfdir}/init.d/dhcp-server ${sysconfdir}/default/dhcp-server ${sysconfdir}/dhcp/dhcpd.conf"
FILES_${PN} += "${sbindir}/dhcrelay ${sysconfdir}/init.d/dhcp-relay ${sysconfdir}/default/dhcp-relay"
FILES_${PN} += "${base_sbindir}/dhclient ${base_sbindir}/dhclient-script ${sysconfdir}/dhcp/dhclient.conf"
FILES_${PN} += "${bindir}/omshell"
RDEPENDS_${PN} = "bash"


So How should I config bitbake to get my image with dhcp by running bitbake ONLY ONCE?


Thank you.

There is no "dhcp" package, only dhcp-client, dhcp-relay, dhcp-server.
Pick the functionality you need and use the appropriate package(s)

You are confusing packages with recipes.  Bitbake only knows how to
build recipes which in turn create packages.  Most of the time, the
packages have the same name as the recipe, but not always.  Sometimes
a recipe only creates "component" packages which, as in the case of dhcp,
do not include a package with exactly the same name as the recipe.

In order to get any of these component packages built, one needs to
tell bitbake to build the recipe (if you are trying to force it on
the command line).  However, the image needs to use the package names,
as that's what gets installed.

Maybe a bit confusing, but that's how it works.

Should I add both the recipe name(dhcp) and the package names(dhcp-xxx) into IMAGE_INSTALL of the image's recipe? If so, how does bitbake know which name in IMAGE_INSTALL is for recipe and which is for package?

As I said above, you use recipe names when you are running bitbake
from the command line, e.g.
   % bitbake dhcp
   % bitbake core-image-minimal
As part of the process of building recipes, bitbake learns what _packages_
are created by each recipe.  Thus, inside recipes, you use package names,
not recipe names.  So to add dhcp-client to your image, simply add that
package, not the recipe name.  bitbake will then realize that it needs to
build the dhcp _recipe_ in order to build the dhcp-client _package_

This is the difference between a "DEPENDS" and an "RDEPENDS" as well.  DEPENDS 
are recipe names or recipe provides (think source code level).  While RDEPENDS 
are "runtime" depends on binary package name, or some other provide on a binary 
package level.

For an image or task, you would add "dhcp" to the DEPENDS, and dhcp-client to 
your RDEPENDS.  (It happens that an image recipe is a bit unique and RDEPENDS is 
specified as IMAGE_INSTALL...)
