Problem linking - what does this error mean?

[Dan Mercer]

I'm trying to install Oracle on a Debian Linux system
(actually a LindowsOS machine). It blows up trying to link several programs
with the following message:

/lib/libgcc_s.so.1: undefined reference to `dl_iterate_phdr@GLIBC_2.2.4'

Oracle doesn't support Debian, so no help there. I've invested quite a lot
of time using apt (under aptitude) to bring the Lindows box up to snuff.
I'm running gcc 3.0 and glibc 2.2.5. Although this problem has similar
symptoms to problems installing Oracle as seen before, the solutions
proposed do not work.

The problem is, I don't understand the error message. I think I might
be able to rectify the problem if I only understood the error message.
dl_iterate_phdr is in libc.a. I tried extracting dl-iteratephdr-static.o(sic)
and dl-iteratephdr.o and linking against them - still no success.

What is ld looking for? Why the @GLIBC_2.2.4?

Please help

This says: "/lib/libgcc_s.so.1 has a dependency on symbol
dl_iterate_phdr(), version GLIBC_2.2.4, but no such symbol was
found in any library at runtime"

This symbol is normally found (defined) in libc.so.6

In the process, you probably ended up with a weird mixture of
glibc-2.2.5 and whatever Lindows originally shiped with.

Run "ldd failing-exe", find out which libc.so.6 it binds to, and
check whether that libc.so.6 defines dl_iterate_phdr(). It probably
doesn't, and must be removed (but do so *very* carefully -- messing
up libc.so.6 can make the system unbootable in no time).

Which I have in /lib - it's a link to /lib/libc-2.2.5. /usr/lib has
a libc.so - but it's only 178 bytes long. I tried symbolically linking
/lib/libc-2.2.5 to /usr/lib/libc.so but that had no effect. I was able
to get Oracle to install by adding -Wl,--allow-shlib-undefined in a file
oracle uses to get load lib options from (I had to remove the line
when I installed the Client because the server software uses gcc
to link and Client uses ld).

I did ldd against one of the programs that finally compiled and it links
against /lib/libc.so.6. nm against the library gets me "no symbols".
I can grep dl_iterate_phdr from the library. Does it not recognize the VERSION?
If not, why not.

Thanks for the help,
