Thanks Carlos,

yes, now I understand tls need it.

I would like to build glibc2.7 for using at native arm
environment,exactly need glibc >= 2.5 for running embedded java on
armv5 - kernel2.6.34.1.

now configure like that.
BUILD_CC=gcc \
CC=/home/tknv/Tool/arm-none-linux-gnueabi/arm-2010q1/bin/arm-none-linux-gnueabi-gcc
\
AR=/home/tknv/Tool/arm-none-linux-gnueabi/arm-2010q1/bin/arm-none-linux-gnueabi-ar
\
RANLIB=/home/tknv/Tool/arm-none-linux-gnueabi/arm-2010q1/bin/arm-none-linux-gnueabi-ranlib
\
AS=/home/tknv/Tool/arm-none-linux-gnueabi/arm-2010q1/bin/arm-none-linux-gnueabi-as
\
LD=/home/tknv/Tool/arm-none-linux-gnueabi/arm-2010q1/bin/arm-none-linux-gnueabi-ld
\
../../glibc-2.7/configure \
--with-headers=/home/tknv/src/kernel-2.6.34/linux-2.6.34.1/include \
--prefix=/usr/arm \
--with-binutils=/usr/bin \
--enable-kernel=2.6.34.1 \
--enable-add-ons=ports,nptl \
--host=arm-none-linux-gnueabi \
--target=arm-unknown-linux-gnu \
--build=i686-pc-linux-gnu 2>&1 | tee configure.out

now this configure works well,then
make 2>&1 | tee make.out
But still not success.
I got same error that none limits.h file.
>> ../include/limits.h:125:26 error: limits.h: No such file or directory.
>> Interesting which limits.h are none...

thanks.
