Dongxiao Xu - Sept. 12, 2011, 8:33 a.m.
For supporting multilib, architecture information is needed in package
require/provide/suggest/recommend fields.

Use DEFAULTTUNE value as the postfix.

For "all" arch recipe, it requires "all" arch recipe with no postfix,
but provides all possible multilib archs.

For example, qemu-config:

Requires: rsync
Requires: update-rc.d
Requires: task-core-nfs-server
Requires: distcc
Requires: oprofileui-server
Requires: dbus-x11
Requires: bash
Provides: qemu-config.x86
Provides: qemu-config.x86-64

For other recipe like zlib:

Requires: libc6.x86-64 >= 2.13
Provides: zlib.x86-64

[YOCTO #1457]

This patch is incorrect.  Architectural information should not be in the
dependencies within RPM packages.

RPM is expected to find the proper version of a package to install based on the
existing dependency information.  I'm in the process of investigating why
certain items are not found properly.

Take "task-core-boot-1.0-r8.qemux86_64.rpm" as an example, and it has dependency on tinylogin, how can it determine whether it is depends on " tinylogin-1.4-r7.x86_64.rpm" or "tinylogin-1.4-r7.x86.rpm".

Thanks,
Dongxiao

In this case, it should not matter which one it uses.  If the dependency is on
"tinylogin", then either of them fulfills the dependency.  RPM should be
selecting which one to bring in using it's internal policy manager.  (I believe
the default is that 64-bit wins...)

For libraries where it does matter, the dependency system should already be
finding the correct architecture for the library.

This does raise an issue in my mind though.  Is an architecture for "tasks"
justifiable?  Why isn't the task-core-boot an all or noarch package?

Is there any difference between a task-core-boot and "lib32-task-core-boot"?

Should we expect a difference between the two?

I think it DOES matter on which one it uses. Thinking the case that if a user wants to build a pure 64 bit system, and if it could not correctly choose the 64 bit of tinylogin, then his system will be contaminated with 32bit programs/libraries. 

Also during my testings, I found rpm will select the "wrong" version (x86 tinylogin).

Thanks,
Dongxiao

With the current way oe-core processes packages into images it uses the
dependencies.. so no matter what you have built you are only guaranteed that the
resulting image contains that final dependency and whatever is needed to make it
"work".  There is nothing that says (today) that you will get a pure 64-bit or
32-bit system -- other then as an artifact of only building 32-bit or 64-bit
software.

There are different strategies we can use to deal with these situations.

1) Resolve the "base" non-multilib system "first", then augment it with the
multilib components.  This results in a "base system" + alternative packages.

2) Resolve the system as whole, including multilibs, and use the policy
components to determine the "best match".  (best match may not be working right
today)  This results in a system based purely on dependency matches.

Either way, our current implementation doesn't quite match either of them.
We're closer to the second version of the implementation today....

If the base system approach is what we want, vs the pure dependency based
system, then we will need to change the way the dependencies are being resolved
and the ordering of the resolution in the packages_rpm.bbclass (or
rootfs_rpm.bbclass).  Basically:

*) take the list of dependencies and filter out any multilibs, and only scan
them against the base archs.

*) add to that resolution any multilib components that had been filtered out and
scan against the all archs.

....

*) install as we do today

Let me take another case as an example during my debugging to this issue.

Thinking that you have built out an base qemux86-64 image, and several lib32 multilib packages. Due to the wrong selection when doing RPM, we have several packages (like libgtk), which need x86-64 version installed, however they are replace by 32bit packages. The do_rootfs process succeeded, but when booting the image, some Xserver programs fail to find /usr/lib64/libgtk.so, because in the system only /usr/lib/libgtk.so is installed, which caused the X start failure.

I ever tried the second approach to fix the problem, however it failed.

I split the installation into two parts as you mentioned, first part is to install the base arch packages, and it does succeed. The second part is to install resolution to multilib components, when calculating the dependency, we will find "package xxx is already installed" error will be detected again by the "justdb" installation. I think there are wrong RPM dependency when installing lib32 multilib packages. showed as follows:

Due to the wrong selection when doing RPM, we have several packages (like libgtk), which need x86-64 version installed, however they are replace by 32bit packages. The do_rootfs process succeeded, but when booting the image, some Xserver programs fail to find /usr/lib64/libgtk.so, because in the system only /usr/lib/libgtk.so is installed, which caused the X start failure.

That is a completely different issue.  If applications need the 64-bit libraries
and the 32-bit ones are fulfilling the dependencies, then we have a dependency
mismatch.  Libraries should contain dependency information (within RPM) that
properly describe the ELF ABI as an artifact of the dependency generation.  This
is a defect we should be able to resolve in the package_rpm.bbclass.

I'll attempt to look into it today, unless someone beats me to it.

The second part is to install resolution to multilib components, when calculating the dependency, we will find "package xxx is already installed" error will be detected again by the "justdb" installation. I think there are wrong RPM dependency when installing lib32 multilib packages. showed as follows:

This is a bit strange.  It should have detected from the resolution code that
the item was already installed and doesn't need to be re-installed -- unless the
above ELF types are causing this issue as well as the one described above.
