Hi

(.text._ZN14fpga_floorplan6gurobiEv[_ZN14fpga_floorplan6gurobiEv]+0x2de2): undefined reference to `GRBModel::write(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'

  It is possible that you have to re-compile the Gurobi C++ API. We discuss this issue in the Knowledge Base article How do I resolve "undefined reference" errors while linking Gurobi in C++?

  If this does not help, could you please post the whole error message you get?
