[Boost-users] cross compile application include boost-lib

Hello, I try to use this application https://github.com/repetier/Repetier-Server on my mips-based router. Sorry, I'm not a developer. Please could someone explain the cross-compiling steps for Linux (I use Ubuntu 14 x86 as build system). gcc/g++ toolchain for mips is from this project http://freetz.org/wiki/help/howtos/common/newbie.en. Do I have also to cross-compile boost for mips or only install the Ubuntu-source-package (sudo apt-get install libboost-all-dev). Thanks for your help and best regards, Thomas
