For two packages with the same name, but different architectures -- the non-ELF files must be identical (or different file names in each package.) The ELF files are identified by type and there is a resolution mechanism within RPM to determine which is the 'preferred' version. We do NOT have the resolution mechanism set, so the first package installed 'wins'. So if you do two packages in two separate transactions, the first version installed will be kept. If you do it in one transaction, then I believe it ends up being the last version [or maybe it's random due to sort order?] There is a Yocto Project defect to configure the RPM multilib settings, but so far it's just sat there, as nobody has either needed it -- or cared enough to implement it. The reality is installed two packages with the same /bin, /sbin binaries is rare these days.. it's much more useful to install the libraries. The code you have below may turn out to be a performance improvement.. (each smart/rpm transaction takes setup and cleanup time, so multiple transactions are slower then one larger transaction.) But it's likely not fixing the actual problem you have. # The default transaction color. This value is a set of bits to # determine file and dependency affinity for this arch. # 0 uncolored (i.e. use only arch as install hint) # 1 Elf32 permitted # 2 Elf64 permitted # 4 MIPS reserved %_transaction_color 3 (4 BTW is MIPS64 - n32) _transaction_color of 3 indicates we allow Elf32 and Elf64 to be installed.. There is a second item: _prefer_color that is used to define which item should be installed when there is that ELF conflict. The numbers above follow there as well. By default I believe it sets itself to '2' when doing a single transaction installed, preferring Elf64. --Mark > This commit restores the functionality to the original one, before > migrating to python: feed all the packages to smart, apart from attempt > only ones which are installed separately. > > Signed-off-by: Laurentiu Palcu > --- > meta/lib/oe/rootfs.py | 16 ++++++++++++---- > 1 file changed, 12 insertions(+), 4 deletions(-) > > diff --git a/meta/lib/oe/rootfs.py b/meta/lib/oe/rootfs.py > index b6baf77..9162e52 100644 > --- a/meta/lib/oe/rootfs.py > +++ b/meta/lib/oe/rootfs.py > @@ -317,10 +317,18 @@ class RpmRootfs(Rootfs): > > self.pm.update() > > - for pkg_type in self.install_order: > - if pkg_type in pkgs_to_install: > - self.pm.install(pkgs_to_install[pkg_type], > - [False, True][pkg_type == "aop"]) > + pkgs = [] > + pkgs_attempt = [] > + for pkg_type in pkgs_to_install: > + if pkg_type == Manifest.PKG_TYPE_ATTEMPT_ONLY: > + pkgs_attempt = pkgs_to_install[pkg_type] > + continue > + > + pkgs += pkgs_to_install[pkg_type] > + > + self.pm.install(pkgs) > + > + self.pm.install(pkgs_attempt, True) > > self.pm.install_complementary() > >
