Hi All,
This issue could be reproduced only by building multilib packagegroup
package in the first time. [YOCTO #5532]
*Step:
1) bitbake packagegroup-core-nfs-server
2) bitbake lib32-packagegroup-core-nfs-server
Only the first time to do the build has this issue:
...
WARNING: The recipe lib32-packagegroup-core-nfs is trying to install
files into a shared area when those files already exist. Those files
and their manifest location are:
/home/jiahongxu/yocto/build-20131120-yocto-qemux86-64/tmp/deploy/rpm/all/packagegroup-core-nfs-server-1.0-r2.all.rpm
Matched in manifest-allarch-packagegroup-core-nfs.deploy-rpm
*Analysis:
- The following commit message is the background which come

[YOCTO #4532] Mark Hatle
In deb/ipk on a multilib package, the package name has specific
multilib
references in it. I.e. the alternative libraries start with something
like lib32-... This was done primarily because deb/ipk do not
allow two
packages with the same name (but different architectures) to be
installed at the same time. So the name has to be unique.
In RPM however, the names of the packages and matches with the
architectures and if they are not the same we can do these multilib
installs.
- For this rpm multilib packagegroup issue, the multilib and non-multilib
packages have the same name 'packagegroup-core-nfs-server', and
the same architectures 'all'.
*Solution
- One possible fix is as Mark Hatle suggested simply to follow the
deb/ipk package
naming, but this causes a design advantage of rpm. When a package has a
dependency on 'bash', we really don't care what bash is installed, only
that -a-
bash is installed. In the deb/ipk case, the lib32- packages would end
up with a
lib32-bash dependency and you could potentially end up with two 'bash'
packages
being installed.
- Tweak oe-core commit 1674541ed83fa4645f2e078f65fe0f878527ee6e
'multilib: fix allarch/kernel/module-base multilib issues', skip the
packagegroup
allarch recipes in multilib_virtclass_handler and extend PROVIDES/RPROVIDES
for packagegroup allarch recipes. It will not build the multilib
packagegroup allarch
recipes if the same packagegroup allarch recipes has already been built.
But I think it's a bad idea, the previous packagegroup allarch check is
reasonable.
- We could simply add PACKAGE_ARCH = "${MACHINE_ARCH}" in each
packagegroup allarch recipe to avoid the QA Warning, but it actually
doesn't work
at the image do_rootfs time, the smart could not correctly find the RDEPENDS
between multilib and non-multilib packagegroup packages.
- Is it necessary to fix the multilib packagegroup issue, it seems the
warning
occurs on the world building, we rarely build both of the multilib and
non-multilib
for one package at the same time , we could simple tweak the sanity check
to ignore the warning.
Any suggestion is welcomed.
