Hi,
Hacking the recipe according to: martin@dell:~/work/z7000-distro-zcu102/meta-openembedded$ git diff diff --git a/meta-oe/recipes-connectivity/zeromq/cppzmq_git.bb b/meta-oe/recipes-connectivity/zeromq/cppzmq_git.bb index a64745c94..aba1d6edb 100644 --- a/meta-oe/recipes-connectivity/zeromq/cppzmq_git.bb +++ b/meta-oe/recipes-connectivity/zeromq/cppzmq_git.bb @@ -13,9 +13,11 @@ S = "${WORKDIR}/git" do_install () { install -d ${D}/usr/include + install -d ${D}/etc install -m 0755 ${S}/zmq.hpp ${D}/usr/include/ + install -m 0755 ${S}/zmq.hpp ${D}/etc } -PACKAGES = "${PN}-dev" +PACKAGES = "${PN}-dev ${PN}" RDEPENDS_${PN}-dev = "zeromq-dev" triggers both ${PN}-dev and ${PN} variants to be packaged and included by the image. Leaving out the installation into /etc causes ${PN} package not to be generated and the image generation does not pick up the ${PN}-dev variant. In essence, it looks like image generation disregards recipes residing exclusively in the ${PN}-dev variant - question is whether this is intended or not?

If you look at the recipe, you'll notice it's re-defining the PACKAGES variable. Then, it's not generating a package called 'cppzmq', but only one named 'cppzmq-dev'. That said, I'm not sure why you'd want to add a package which only provides development headers to your target image... I understand your doubt here. The header file installed is a wrapper around zeromq and thus DEPENDS/RDEPENDS on this library. zeromq is included in the image, for which the SDK is generated, hence I would expect this to be a valid use case? Anyhow, I realized that the recipe does not even work in a BB environment - the following is encountered for an image including the package: ERROR: Nothing RPROVIDES 'cppzmq' (but /home/martin/work/z7000-distro-zcu102/poky/meta/recipes-core/images/core-image-minimal.bb RDEPENDS on or otherwise requires it) NOTE: Runtime target 'cppzmq' is unbuildable, removing... Missing or unbuildable dependency chain was: ['cppzmq'] ERROR: Required build target 'core-image-minimal' has no buildable providers. Missing or unbuildable dependency chain was: ['core-image-minimal', 'cppzmq'] I wonder why this occurs when the recipe is indeed present: martin@dell:~/work/z7000-distro-zcu102/build$ bitbake-layers show-recipes cppzmq NOTE: Starting bitbake server...
