By default, ${PN}-dev RDEPENDS on ${PN} automatically, if not changed:

(this is my first foray into messing with SDKs so these will be simple questions.) as a test, i built a core-image-minimal for qemuarm64, then started playing with: TOOLCHAIN_HOST_TASK_append = " ..." to see what was added to the host manifest file. when i added: TOOLCHAIN_HOST_TASK_append = " nativesdk-expect" then, sure enough, that package was added to the host manifest file. however, when i added the -dev package: TOOLCHAIN_HOST_TASK_append = " nativesdk-expect-dev" then *both* packages were added, as in, the regular package was dragged along with the -dev package, which *seems* reasonable, but where in the code (class file?) is this processing done? put another way, under what circumstances will adding a -dev package to the host portion of the SDK necessarily add the primary package? rday -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

The implication of that is that you want to use a header file from a host component of the SDK to be able to compile additional tools etc to run on the host after the SDK has been created? Normally the SDK tools etc which run on the host are all compiled as part of creating the SDK, not afterwards. > i haven't spent a lot of time messing with SDKs (that is about to > change), but as i read it, if one wants to add the contents of any > given development package to the host SDK, it would look like: > > TOOLCHAIN_HOST_TASK_append = " nativesdk-fubar-dev" > > i have no idea what the rationale is here, i'm just trying to > address the question, which in addition asks, "if you add something > like that to the host side, is it automatically added to the target > side?"
