[OpenWrt-Devel] how can i *deselect* building rrdtool?

[Ted Hess]

Some observations on things that build when you think they shouldn’t... This 
is something I noticed a while ago and can construct an example, but have 
been unable to understand why things work this way – bug or feature?

Let's say you have a package - call it utility xyzzy. In the Makefile, you 
declare 2 additional packages: lib-x and lib-y along with the xyzzy utility. 
lib-x is dependent on libfoo and libbar. lib-y is only dependent on libfoo 
only. The xyzzy utility is dependent on lib-y and NOT lib-x. However, if I 
select xyzzy and hence lib-y is selected by default, when you build, libbar 
will be built (but not installed) even though it not selected in the build 
config as you have observed.
