Dear Dave Very thanks for your help! I tried it, but it still shows the same link errors. I guess the errors possible from "cxx11". All the best! Wenjie Liu

Hi Wenjie,

It looks like TinyXML might not have been installed correctly. One option might be for you to use the Debian package (libtinyxml-dev) and see if that is better?
