[yocto] do_rootfs failure: no package provides [required library].so()(64bit)

[Ben Randall]

Hello friends,

I'm trying to put together a recipe for the Ceph stack since I
couldn't find one in the wild.  Right now I have Ceph and all of its
dependencies compiling, however the build process fails during
do_rootfs.  Here is the relevant build output:

Warning during do_package_write_rpm:
"WARNING: QA Issue: ceph requires libcryptopp.so()(64bit), but no
providers in its RDEPENDS [file-rdeps]"

Error during do_rootfs:
"ERROR: Unable to install packages. Command [path]/smart --quiet
--data-dir=[path]/smart install -y [packages listed in
IMAGE_INSTALL]@[core2_64 OR genericx86_64] returned 1:
error: Can't install ceph-0.93-40 at core2_64: no package provides
libcryptopp.so()(64bit)"

I believe the issue involves Ceph not identifying or linking against
the required library libcryptopp/crypto++.  I'm including libcryptopp
via a recipe found here:
https://github.com/coldnew/meta-coldnew/tree/master/recipes-support/cryptopp.
I added additional pkg-config .pc files and aliases to cryptopp's
RPROVIDES to accommodate the variety of naming conventions that
surround it (cryptopp, crypto++, libcryptopp, libcrypto++), but other
than that the recipe is stock.

I can confirm that libcryptopp is being built and staged (in
package/usr/lib/, packages-split/libcryptopp/usr/lib/,
sysroot-destdir/usr/lib/, and image/usr/lib/).  Also, I will note that
this package and its dependencies are building for core2_64 while my
MACHINE target is genericx86_64.  I don't think that should be a
problem though...

Thanks for your time!

Ben
