[PATCH 0/1] Fix browser crash on PPC

[edwin.zhai]

From: Zhai Edwin <edwin.zhai@intel.com>

All,
    This patch use glib as unicode backend to avoid browser crash
            
webkit-gtk depends on ICU for the unicode, but ICU is not safe when build and
target system owns different endian. ICU's community is not responsive to make
a patch for this, so glib is used as work around here.

[YOCTO #1570] got fixed

Note: any big-endian target will probably suffer the same as PowerPC,
so should this not also be extended to those, e.g. big-endian MIPS, etc?

That is a really big change since the backends don't have equivalent functionality.

And that doesn't merge into oe-core, so I can't test it.

I've merged this however I'm not 100% happy with this as the final fix.
I'd ask that:

a) The bug remains open (re-prioritised appropriately) about the
remaining issues that still exist in ICU
b) We add something to the ICU recipe which stops it building when the
endianess isn't correct (host matches target) so nobody can built it and
have it not work.

Cheers,

Richard

Why not accept my patch that provides a working dataset?  I doubt
that you're ever going to get the ICU folks interested to the point
of fixing this correctly and this solves the problem without the
[IMO undesirable] side effect of using different libraries on
different architectures (for webkit-gtk).

Provideding a big binary in yocto website is not clean, but it should avoid 
potential side effect.

This is ultimate solution. I remember ICU community is not so active to do it.

RPM packaging issue?

[Laurentiu Palcu]

Hi list,

I was trying to build core-image-gtk-directfb and ended up with this error:

Log data follows:
| DEBUG: Executing shell function do_rootfs
| ERROR: Function failed: do_rootfs (see
/home/lau/yocto/build/tmp/work/qemux86-poky-linux/core-image-minimal-1.0-r0/temp/log.do_rootfs.4857
for further information)

| Processing task-core-boot...
| Processing module-init-tools...
| Unable to find package module-init-tools (module-init-tools)!
NOTE: package core-image-minimal-1.0-r0: task do_rootfs: Failed

module-init-tools is provided by kmod package and is in the RDEPENDS of
task_base recipe.

Then I tried to add module_init_tools to CORE_IMAGE_EXTRA_INSTALL and
build core-image-minimal (just for testing), the same result.

The interesting thing is that this didn't happen if the packaging format
is ipk.

Anybody know anything about this issue?

Thanks,
Laurentiu

The issue here is that starting to distribute binary blobs gets us into
potentially troubled waters. It also means that for every new tune or
target (say mips BE), we'd need another blob. Add something like uclibc
and the problem gets worse.

So I can see the attraction of the solution and it works well for
particular cases but it isn't something I think can be made to work in
OE-Core in the general case :(.

I did wonder whether we could post process the binary to correct the
endianess of the data in the file?

Cheers,

Richard

The IMAGE_INSTALL list has module-init-tools in it.  This list is based on 
package name and not "dependency" or "provide" name.  The package 
module-init-tools no longer exists in the system, there is only a runtime 
provide from the kmod package.

This ensures that any package that requires module-init-tools will work 
properly, but anyone adding module-init-tools to the IMAGE_INSTALL it will fail 
as you've seen above.
