[yocto] Can't get *.a's into SDK sysroot

[Zoran Stojsavljevic]

Hello Andre,

> RDEPENDS_${PN}-dev += "${PN}-staticdev"

I also read this email, and decided to investigate myself. Since I
wrote meta-mylayer with cannelloni recipe in it.

To find out if the recipe works correctly, and it is incorporated
(upfront) in ROOTFS, I did the following:
[1] Did the compilation of the clean tree;
[2] After that, I did: bitbake -s | grep cannelloni -> yes, the build
system sees it;
[3] Changed to ${TMPDIR}/work and issued the command: find . -name cannelloni

To my surprise, the search produced empty results.

Then I added your line to the cannelloni recipe: RDEPENDS_${PN}-dev +=
"${PN}-staticdev"

Again, bitbake -c cleanall cannelloni, then bitbake cannelloni, and
step [3] produced visible results.

Now I see it in the .../tmp/work/...

But, there were NOT any changes in: .../tmp/deploy/images/beaglebone/
directory (in ${build} directory, I guess)???

So, what I need to do to see build components changed (since I assume,
cannelloni still did not make it in ROOTFS)???

Thank you,
Zoran
