Cross compile glibc for arm, got undefined reference to some unwind functions

Question

Now I need to build glic-2.15 for our armv7 soc platform. I follow the following steps to build it:

Download and extracted glibc-2.15 and glibc-ports from http://ftp.gnu.org/gnu/libc/

mkdir build-glibc
cd build-glibc
echo "CFLAGS += -D__ARM_ARCH_7__ -D__LINUX_ARM_ARCH__=7 -march=armv7 -U_FORTIFY_SOURCE -fno-stack-protector" > configparms
PATH={toolchain}/bin
BUILD_CC={build}/bin/gcc
CC={toolchain}/bin/arm-linux-gnueabihf-gcc
AR={toolchain}/bin/arm-linux-gnueabihf-ar
RANLIB={toolchain}/bin/arm-linux-gnueabihf-ranlib
../glibc-2.15/configure --prefix=/linaro-toolchain/ \
                        --exec-prefix=/linaro-toolchain/ \
                        --host=arm-linux-gnueabihf \
                        --build=i686-pc-linux-gnu \
                        --disable-profile --enable-add-ons=ports,nptl \
                        --enable-kernel=2.4.0 --with-tls --with-__thread \
                        --without-gd --without-cvs \
                        --with-headers=/linaro-toolchain/arm-linux-gnueabihf/libc/usr/include \
                        --disable-multilib --enable-shared \
                        libc_cv_forced_unwind=yes \
                        libc_cv_c_cleanup=yes \
                        lic_cv_gnu89_inline=yes lic_cv_ssp=no \
                        libc_cv_ctors_header=yes
make all

I met many issues and got stuck with this one:

Is there someone have any ideas about this?

Answer 1

Finally I found it's because my Makeconfig missed -lgcc_eh. We have to add this when GCC was built for dynamic.

It seems you can remove this flag if your GCC is built only static.
