[Linux-ia64] That getpagesize() problem again!

[Linux-ia64] That getpagesize() problem again!

[Francis Galiegue]

When trying to install only two packages via RPM in a chroot, this is what I
get:

rpm: ../sysdeps/unix/sysv/linux/ia64/getpagesize.c:36: __getpagesize: Assertion
`_dl_pagesize != 0'
failed.

Then, abort and core dump.

What I'd like to know is why, in the glibc file mentioned in the error,
__getpagesize is defined as such:

int
__getpagesize ()
{
  assert (_dl_pagesize != 0);
  return _dl_pagesize;
}

(that's glibc 2.2.1, but 2.2 exhibits the same behaviour)

This looks all the more strange that you can define the page size during kernel
compile! A sample test program which I made using the getpagesize() syscall
yields the correct value, though...

What should I do?

If the getpagesize syscall works, then your kernel is too old.

You need to run kernel 2.4.0-test9 with the 001030 patch or later.
Earlier versions didn't pass AT_PAGESZ in all cases.

Actually the problem is that Francis' rpm binaries have been compiled
and linked statically against an old version of glibc that didn't get
the pagesize from AT_PAGESZ.

Francis you need to get a proper set of RPM binaries for your machines
linked against the new library.

Uhwell, I compiled against glibc 2.2.1...

Anyway, I'm going to reboot under 2.4.0 + patch and see if this cures the
problem... More info later...
