From: Andrei Gherzan <andrei.gherzan@windriver.com>

Enable 64-bit math support in the expr applet. This will make
the applet slightly larger, but will allow computation with very
large numbers.

[YOCTO #1767]

Is anyone working on more fine grained control of busybox? Some ideas include:

1) configure via PACKAGECONFIG?

2) supply a defconfig for busybox?

3) multiple busybox recipes?

indeed, I think maybe providing specific config file for specific
machine is better, but not spliting the config to fragments.

You could take a look at the busybox-config.inc stuff in oe-classic as a
starting point.  It doesn't do PACKAGECONFIG (since oe-classic doesn't
have that) but it can do the equivalent with DISTRO_FEATURES.

At Wind River we've discussed using the kernel configuration fragment patching 
process as a way to control busybox.  This would allow the recipe to provide a 
default fragment (configuration), with machines, architectures, and other 
configurations providing additional fragments -- that together would produce the 
busybox that the end use wants.

I think this is a better long term approach then hacking the defconfig file each 
time it's not quite right for a system.  (We may still need to modify it over 
time, but the modifications need to be considered "generic" based on the use of 
busybox in say core-image-minimal...)

I agree with the concept of the idea and long term solution however I also
think it needs to be well documented otherwise it is going to be a problem,
instead of a solution.

When I tried to use the kernel configuration fragment from Yocto I couldn't
figure it out by myself and it seems very undocumented thus its learn curve
is not as good as I'd hope for...

Just to confirm, I have seen discussion about finer-grain control over 
bitbake configuration, but are there any direct objections to this 
change going in?

This bug should be fixed already:
http://lists.linuxtogo.org/pipermail/openembedded-core/2011-December/014487.html

Please inform if my fix doesn't work.

As i could see that patch has nothing in common with this bug. Yes, it uses
expr from busybox... but that is all. No fix for 64bit numbers support.

Sorry, my fingers were faster than my head. I thought this bug was 
opened because of yocto time set issue:
https://lists.yoctoproject.org/pipermail/yocto/2012-January/006437.html

I see this is general issue. You can forget my previous message.

The need for something like this was also highlighted during my
poky-tiny work for Yocto. We need a config fragment manager for busybox,
although the yocto-kernel tools may be overkill. We also need something
that adjusts those fragments based on DISTRO_FEATURES, especially the
libc bits.

I can see the value of busybox "profiles", such as tiny and standard for
a start. The yocto-kernel tooling might be a good fit for this, but it
could also be accomplished with a couple busybox recipes and the
PREFERRED_PROVIDER mechanism.
