My host is RH9-2.6 ,im trying to compile glibc-2.3.4 in chroot environment,i got a problem:
#../glibc-2.3.4-20040701/configure --prefix=/usr --disable-profile --enable-add-ons --enable-kernel=2.6.0 --libexecdir=/usr/lib/glibc

...
configure:error:working compiler support for visibility attribute is required



below is the information for check:
on host:
$/lib/libc.so.6
....
linuxthreads-0.10...
..

on chroot env:
#/tools/lib/libc.so.6
....
Native Posix Thread Library..

#gcc -v

gcc version 3.4.1

the gcc is compiled with glibc+nptl , is it the reason causing that problem?and any fix idea? thanks

Here I think I might have found the problem if not tell me, OK.
well you put:and probably something else too, but it just stoped at those commands.

But, what you should have put 'If you reading LFS-6.0' is:
Tell me if I'm right.

Yes,that's right, and you will compile it within Kernel 6.0,but did you encounter my problem?

OK, I'm gonna go on a wild hunch and say that aren't the commands you put.

In that case:
Can you post more of the Output, and start with the first instance of any kind of Error down to the end of the Output?

Oh, and just to be certain it's not the commands post them also.
