Vorbis dev - Oct 2001 - Re: Some compile time stuff

M > What is the error produced?  It doesn't appear in the log.

....ah, and now I see why...  Actually, this is a nifty failure, and we
(well, *I*) haven't seen it before.  The libs were apparently
miscompiled;  gcc/ld produced a shared lib missing neccessary shared
lib symbols.

Now all that remains to be seen is if this is a libtool option error,
if your gcc/ld are broken, if they somehow don't match your ld.so, etc...

Internal ELF shared object symbol that's not there and it definately
should be.  Autoconf was failing as it should be, and this is an error
well beyond typical user capability to deal with, so it's not
autoconf's fault for not printing a 'more useful error'.

(Although it occurs to me that appending the autoconf error to list a
bug reporting address *should* be possible).

/usr/local/lib/libogg.so.0 -> libogg.so.0.2.0

/usr/local/lib/libogg.so.0.2.0
OK, I have a few more quick questions that I know Jack and the other
build maintainers will want to know the answers to:

Linux distribution and version
ld.so version (usually part of the filename, eg, ld-2.2.4.so)

gcc --version
ld --version
automake --version 
autoconf --version
libtool --version
nm /usr/lib/libogg.so

...and if you could cut/paste the complete screen output of
'./autogen.sh;make; make install' from an Ogg build, we'd be
grateful.  Probably also the src/Makefile would be useful.

*grumble grumble GNU grumble*  I really want to find this one.

Either your distribution is broken, or you installed a new gcc version without
reading the install instructions.  Bad, bad idea.  You need to install new
binutils as well, and depending on what exact conflict this is (there
were a
few problems with the same symptoms), your libstdc++ and/or your glibc (needs
at least version 2.2) and/or your dynamic loader (ld.so), depending on the
packaging you get it in.  Be sure to get a full binutils, at least a new
ld and gas.
