Hi vda,
I accept your comment and others that it was not a busybox related issue.
Well, here is my situation.I built a small rootfs for my arm pxa270 target
board on the host x86 machine using the latest Buildroot. I then downloaded &
installed iptables(v1.3.8) using
make KERNEL_DIR=/home/sara/cm-x270/linux-2.6.16
CC=/home/sara/BuildRoot/buildroot/build_arm/staging_dir/usr/bin/arm-linux-gcc
LD=/home/sara/BuildRoot/buildroot/build_arm/staging_dir/usr/bin/arm-linux-ld
BINDIR=/home/sara/BuildRoot/buildroot/project_build_arm/uclibc/root/sbin
LIBDIR=/home/sara/BuildRoot/buildroot/project_build_arm/uclibc/root/lib
make BINDIR=/home/sara/BuildRoot/buildroot/project_build_arm/uclibc/root/sbin
LIBDIR=/home/sara/BuildRoot/buildroot/project_build_arm/uclibc/root/lib
install
command install all iptables into the rootfs under
"/home/sara/BuildRoot/buildroot/project_build_arm/uclibc/root" with all
iptables and extension supports are built into linux kernel
"/home/sara/cm-x270/linux-2.6.16" image.
I then boot my cm-x270 target board using setboot os "console=ttySA0,38400
root=/dev/nfs
nfsroot=/home/sara/BuildRoot/buildroot/project_build_arm/uclibc/root
ip=::::cm-x270:eth0".
Now, when I perform MASQUERADE , it couldn't find libipt_MASQUERADE.so but it
is installed in /lib/iptables.
sara:/$ ldconfig -v show /lib , /usr/lib.
ldconfig: uClibc version
/lib:
libc.so.0 => libuClibc-0.9.29.so
libnsl.so.0 => libnsl-0.9.29.so
libdl.so.0 => libdl-0.9.29.so
librt.so.0 => librt-0.9.29.so
libgcc_s.so.1 => libgcc_s.so.1
libncurses.so.5 => libncurses.so.5.6
libutil.so.0 => libutil-0.9.29.so
libcrypt.so.0 => libcrypt-0.9.29.so
ld-uClibc.so.0 => ld-uClibc-0.9.29.so
libpthread.so.0 => libpthread-0.9.29.so
libresolv.so.0 => libresolv-0.9.29.so
libm.so.0 => libm-0.9.29.so
/usr/lib:
libstdc++.so.6 => libstdc++.so.6.0.8
libz.so.1 => libz.so.1.2.3
/lib/iptables is not visible in the system to load the library.
thanks
Sara
