We want to make the C++ API compatible with as many different compilers and compiler versions as possible. We also provide source files for the API so you can build the library yourself using your compiler of choice.
While building a C++ application that uses Gurobi, If the linking process causes "undefined reference" errors like these:
undefined reference to `GRBModel::addVar(double, double, double, char, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)'
undefined reference to `GRBModel::addConstr(GRBTempConstr const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)'
undefined reference to `GRBVar::get[abi:cxx11](GRB_StringAttr) const'
you should recompile the C++ library for the API and replace the old one to resolve any ABI incompatibilities. This can be done from the system command prompt with:
cd /opt/gurobi902/linux64/src/build
make
cp libgurobi_c++.a ../../lib/
