nasty little error with glbc :(

I am using version 6.6 of LFS, and am on chapter 5.7 where i have to compile glbc.
the problem comes after i enter the command to prepare glbc for compliation. I get this!

Code:

checking whether __attribute__((visibility())) is supported... no

configure: error: compiler support for visibility attribute is required

i checked the host requirements and found nothing unusual... everything seems, at least to a noob, to be fine.

how can I fix this?

Hi,

what host system are you using? Please post the commands that you executed before the error occurred. We also need a little more of the output.
As for the requirements, make sure that every program is installed with it's recommended minimal version, e.g. by executing

Code:

gcc --version

bash --version

...

Do this for all programs listed in the host system requirements section.

Hey CRTS, thanks for the reply.
i expected it to take much longer :D

I'm using Ubuntu 9.10 as host, for lack of any specific suggestions from anyone making an LFS.
this is my first lfs, if it isn't apparent enough already :)

before I got the error i executed these commands:

Code:

case `uname -m` in

  i?86) echo "CFLAGS += -march=i486 -mtune=native" > configparms ;;

esac

^^ this one was ok

Code:

../glibc-2.11.1/configure --prefix=/tools \

    --host=$LFS_TGT --build=$(../glibc-2.11.1/scripts/config.guess) \

    --disable-profile --enable-add-ons \

    --enable-kernel=2.6.18 --with-headers=/tools/include \

    libc_cv_forced_unwind=yes libc_cv_c_cleanup=yes

^^ this is the code that gave me the error
and the output was (not the whole thing)

so yeah... im gonna go back and do what you said about the prereqs though, and see what's up.
thanks

EDIT: checked all the host requirements, all good
PLEASE HELP!

Haven't gotten help.
I really wanna fix this before i quit and move to archlinux or something.
any other details necessary?

What did you do to meet these requirements?? Out of the box Ubuntu isn't suitable as host for LFS.

My advise: Use the LFS liveCD instead.

Hope this helps.

I think in chapter 5 when binutils-pass1 and gcc-pass1 is compiled there is a misconfiguration with the ld.

You could try to force gcc to prefer the linker from the host in /usr/bin.

Try this in pass 1 of binutils

Code:

CC="gcc -B/usr/bin/" ../binutils-2.20.1/configure \

--target=$LFS_TGT --prefix=/tools \

--disable-nls --disable-werror



make



make install

and this in pass 1 of gcc

Code:

CC="gcc -B/usr/bin/" ../gcc-4.5.0/configure \

--target=$LFS_TGT --prefix=/tools \

--disable-nls --disable-shared --disable-multilib \

--disable-decimal-float --disable-threads \

--disable-libmudflap --disable-libssp \

--disable-libgomp --enable-languages=c



make bootstrap



make install
