Re: glibc 2.2 vs 2.3 issue back again

The sole version of libc.so.6 on my FC4 system requires 2.4.20
kernel:

$ objdump -sj.note.ABI-tag /lib/libc.so.6

/lib/libc.so.6: file format elf32-i386

Contents of section .note.ABI-tag:
8ec174 04000000 10000000 01000000 474e5500 ............GNU.
8ec184 00000000 02000000 04000000 14000000 ................

[The last 3 numbers signify required kernel version:
0x02 0x04 0x14 == 2.4.20]

If you had a "kernel too old" situation, the exe would just
always fail with "error while loading shared libraries" loader
message.

> ii) could it be that I need additional data files for libc 2.3?

That is most likely cause of your troubles: you've only copied
libraries listed in ldd output, but there are probably other
libraries loaded dynamically by glibc itself.

Either copy all libraries listed by 'rpm -ql glibc' on FC4, or run
Mathematica on FC4 and examine /proc/<mathematica-pid>/maps

This will probably reveal additional libraries you must copy
but didn't.

> But what about locale files?

I've never had problems with mismatched locale/ files (but I don't
usually deal with i18n software).

If these are in fact causing failure, I expect that setting a whole
new chroot'ed environment might be easiest solution.

Unlikely.
