title: Cross Compilation: How to use same libstdc++ on target as on compiling machine
body: <p>I am running openwrt on a TP-Link MR3020 and cross compiling for this device on a x86 ubuntu.
  I am running into problems and the remote debugging doesnt help very much.</p>
  
  <p>Maybe the c++ standard libraries from the toolchain that I use to compile with are different from the ones on the target machine.
  How can I check which version is installed?
  Thanks</p>
