Hi, to those understanding the package dependency logic by heart, I'm trying to achieve something I assumed to be common, but fail to get there with the help of the available documentation.
The short version is this: * package A has an optional feature X provided by package B * package B is optional (feeds package) => feature X should be selectable only if B is installed and selected * if feature X is activated, package A depends from package B I did: 1) in Config.in of package A add config WITH_FEATURE_X bool depends on PACKAGE_B prompt "Enable feature X" default n 2) in Makefile of package A add DEPENDS += +WITH_FEATURE_X:B With those changes, build fails due to recursive dependencies, because - symbol PACKAGE_B is selected by WITH_FEATURE_X - symbol WITH_FEATURE_X depends on PACKAGE_B If I leave out the additional line in Makefile of A and in menu select WITH_FEATURE_X, the build of A fails with missing dependency to package B. If I leave out the 'depends on PACKAGE_B' line in Config.in, I can select WITH_FEATURE_X without package B even being installed, which obviously fails building. Is this doable out of the box? What am I missing? BTW, this is about SNMP agentx support for lldpd.
