Hi guys,
I think we should upgrade PREFERRED_VERSION_glibc from 2.6 to 2.9 in
conf/distro/include/sane-toolchain.inc. The reasons are:
Although I haven't tried a build from scratch in a few weeks or so, I
have one known problem with glibc 2.9. I wonder if it's just me or not.
glibc 2.6.1 always works. On my armv4t board gpe-mini-browser2 always
seg faults. I've tried different gcc and binutils combinations. However,
glibc 2.9 on armv5te (imx) or armv7a (omap) work fine for me.
1. Most of distributions have upgraded their preferred glibc to 2.9 long
time ago.
conf/distro/angstrom-2008.1.conf:PREFERRED_VERSION_glibc ?=
"2.9"
conf/distro/angstrom-2008.1.conf:PREFERRED_VERSION_glibc-initial ?=
"2.9"
conf/distro/jlime-2009.1.conf:PREFERRED_VERSION_glibc-initial = "2.9"
conf/distro/jlime-2009.1.conf:PREFERRED_VERSION_glibc = "2.9"
conf/distro/kaeilos.conf:PREFERRED_VERSION_glibc ?= "2.9"
conf/distro/kaeilos.conf:PREFERRED_VERSION_glibc-initial ?= "2.9"
from the above, you can get to know that most distributions have upgraded
their preferred glibc to 2.9 from 2008 ago.
Of course, there are still some distributions which uses old glibc. The only
reason I guess is that we have not updated them for a long time. (for from
tinderbox, you can get to know that these distributions have not been built
for a long time)
2. from tinderbox, you can see that the glibc-2.9 is well-tested, no
glibc-2.6
http://tinderbox.openembedded.net/packages/?name=glibc&page=1
from the above link, you can get to know that the glibc-2.9 not glibc-2.6.1
has had most testing.
3. the last reason is that I have built some projects with glibc-2.6, unless
with the old binutils, the glibc-2.6 always failed to build.
So, I think it is the time to upgrade PREFERRED_VERSION_glibc to 2.9 in
sane-toolchian.inc
Yes I am ok with this. Infact you could even use 2.10.1 now you are at it
and micro already did the change.
