Download flex and cross compile for ARM assuming your ARM cross compiler is located at /opt/arm-2011.09/
wget http://sourceforge.net/projects/flex/files/flex-2.5.39.tar.bz2 tar -xjf flex-2.5.39.tar.bz2 cd flex-2.5.39/ ./configure --host=arm-linux-gnueabi --prefix=/usr/arm-linux-gnueabi ac_cv_func_malloc_0_nonnull=yes ac_cv_func_realloc_0_nonnull=yes make make install
Wide-DHCPv6 has not been updated for some time and uses structures no longer avaliable in glibc without the use of the #define _GNU_SOURCE
