Question: One makefile for multiple packages - No rule to make target

[hansd]

Hi. I have a problem building two custom packets using single makefile and a single custom source code. I have a cmake file that builds two executables. They are supposed to go into separate packages. The source code is the same. The main package builds fine, but the second package is "No rule to make target":

$ make package/dummy-moonshine2-llc/prepare V=s
Collecting package info: done
make[1]: Entering directory '/home/***/openwrt/v19'
make[1]: *** No rule to make target 'package/dummy-moonshine2-llc/prepare'. Stop.
make[1]: Leaving directory '/home/***/openwrt/v19'
/home/***/openwrt/v19/include/toplevel.mk:216: recipe for target 'package/dummy-moonshine2-llc/prepare' failed
make: *** [package/dummy-moonshine2-llc/prepare] Error 2

The base package (or the package defined with PKG_NAME) :

$ make package/dummy-moonshine2/prepare V=s
Collecting package info: done
make[1]: Entering directory '/home/***/openwrt/v19'
make[2]: Entering directory '/home/***/dummy/dummy_router_openwrt/dummy-moonshine2'

I believe I've had a similar problem with slider-support and what helped was using the explicit package names instead of the variable in the Makefile.

Thanks Stan ! I managed to get my two packages finally. I was missing Build/Configure, and I replaced with explicit package names.

Another thing that lured me into not finding the solution was that I cannot write make package/dummy-moonshine2-llc/compile, I must build the main package, and then the build system will build the two packages and put the two ipk files under ./bin/.../
