Libdaemon is a dependancy for radvd.
Download libdaemon and cross compile for ARM assuming your ARM cross compiler is located at /opt/arm-2011.09/
wget http://0pointer.de/lennart/projects/libdaemon/libdaemon-0.14.tar.gz tar -xzf libdaemon-0.14.tar.gz cd libdaemon-0.14 ./configure --host=arm-linux-gnueabi \ --prefix=/usr/arm-linux-gnueabi \ ac_cv_func_setpgrp_void=yes make make install
Now copy libdaemon.so.0.5.0 to your target and update the dynamic linker run-time bindings with ldconfig:
cp /usr/arm-linux-gnueabi/lib/libdaemon.so.0.5.0 /home/export/rootfs/lib
wget http://www.litech.org/radvd/dist/radvd-1.14.tar.gz tar -xzf radvd-1.14.tar.gz cd radvd-1.14 ./configure --prefix= \ --host=arm-linux-gnueabi \ --sysconfdir=/etc \ PKG_CONFIG_PATH=/home/temp/radvd/lib/pkgconfig make make install DESTDIR=/home/export/rootfs
