If I remember right, SDK construction doesn't use DEPENDS or RDEPENDS at all. Rather it takes the list of packages installed into an image, constructs a tree of their dependencies (which is not the same as RDEPENDS), adds -dev to everything in that list, and then that is what gets installed into the SDK.
I generally recommend to not bother with standalone SDKs, and set up a SDK environment directly in the bitbake environment. Much more flexible and easier to maintain: https://docs.yoctoproject.org/sdk-manual/extensible.html#installing-the-extensible-sdk Alex On Wed, 19 Feb 2025 at 10:51, Thilo C. via lists.yoctoproject.org <thilo.cestonaro=thalesgroup....@lists.yoctoproject.org> wrote: > Classified as: {OPEN} > > Hi! > > I'm currently struggling to get a specific paket into the SDK of our image. > > The situation is as follows. > We have a "library" which is generated code and header only.
