Building older glibc

Building older glibc

[Peter Chubb]

Is there a trick to building an older glibc than the head?  I'm
building for x86, and I need a libc.a that'll run against a 2.6.10
kernel --- so I've tried
	bitbake glibc-2.3.2
(and 2.3.5)
And I see :
...
| configure: loading site script /usr/src/oe-sel4/openembedded/site/common
| configure: loading site script /usr/src/oe-sel4/openembedded/site/common
| configure: error: add-on directory "nptl" does not exist

I had the same requirements:
I have a 2.4 kernel that doesn't have:
*nptl
*eabi
so I tried to patch a recent glibc and at the end I end up choosing
uclibc...
The drawback is that it seriously affect my binary compatibility with
glibc(that is to say I can't run the proprietary software that came with
the device...but I want to get rid of that software anyway...so...)
I didn't try or look into eglibc and I'm interested in knowing if it
require nptl

You shouldn't need to get that old.  2.5 or 2.6, with
OLDEST_KERNEL=2.6.10 should work (make sure your machine.conf isn't
overriding the default of 2.4.0).
