[parisc-linux] GNU/Libc 2.3.1 on HP-PARISC requires >= 2.4.19 kernel.

[Carlos O'Donell]

debian, parisc, debian-glibc,

Hi, my name is Carlos, and I cause all your nightmares with glibc on
HPPA :)

Currently in unstable for HPPA - glibc 2.3.1-5
Currently in testing  for HPPA - glibc 2.2.5-15

What?
=====
During the changeover from GNU/Libc 2.2.x to 2.3.x HPPA has changed
it's minimum GNU/Libc kernel version to 2.4.19.

Why?
====
- More testing.
- Bugs fixed in unaligned handlers.
- Trap handler fixes.
- More things than you can shake a stick at, and all thanks to the
  wonderful kernel hacking team that parisc-linux has.

No.
===
If you do not wish to upgrade your kernel then I suggest you pin glibc at
the particular version that you feel is good for you. The debian glibc
package for 2.3.1-6 has a preinst check against the system kernel version
(e.g. You can't install it without the right kernel).

Sorry.
======
I apologize for the initial oversight that meant there was no preinst
check, and one or two individuals have suffered through some serious
system reconstruction. I apologize. I really do. I owe you both beers :}

I recommend that you _do_ _not_ upgrade glibc on HPPA until 2.3.1-6.

When?
=====

glibc 2.3.1-6 is going into unstable in the next few days (time
permitting).

Thanks for your time :)

Cheers,
Carlos O'Donell.

I feel this was a mistake.

That's great, but there are still problems with 2.4.19 and 2.4.20.  I think
you're doing our users a disservice by requiring them to upgrade to 2.4.19.
Why not relax the minimum version requirement down to 2.4.17?

I agree that it was probably a mistake at the time since 2.4.19 seemed
to solve a lot of problems... though in hindsight they are still too
unstable to push forward on all of our users.

Hrmm... *Carlos mulls for a few hours*

I'll relax it to 2.4.17 in debian, but I'll leave the upstream
requirement of 2.4.19.

Being perverse, I tried installing 2.3.1-5.  I hit the same problem
that Joel mentioned previously, the old dynamic loader doesn't define
GLIBC_PRIVATE.  I was trying to install glibc privately in a prefix of
my selection.  I have been using LD_LIBRARY_PATH to select my library
path.  However, this no longer works since all system binaries are
linked using /lib/ld.so.1 and it isn't compatible with the 2.3.1
libraries.  Is there a way around this?

Well, I don't think it is perverse. I have already more than 10 days
uptime with a machine, that runs completely with 2.3.1 (and this machine
was only for about 13h idle).

In order to run with the new ld.so, you may try the following:

<prefix>/lib/ld.so.1 --library-path <prefix>/lib:<prefix>/usr/usr/lib
command

or you set up a chroot system with all needed programs.
