<br>
This is the suspicious bit... If you look at the recipe, you'll notice<br>
it's re-defining the PACKAGES variable. Then, it's not generating a<br>
package called 'cppzmq', but only one named 'cppzmq-dev'. That said,<br>
I'm not sure why you'd want to add a package which only provides<br>
development headers to your target image...</div>
<div class="PlainText"><br>
</div>
<div class="PlainText">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?</div>
<div class="PlainText"><br>
</div>
<div class="PlainText">Anyhow, I realized that the recipe does not even work in a BB environment - the following is encountered for an image including the package:</div>
<div class="PlainText"><br>
</div>
<div class="PlainText">
<div>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)</div>
