I can use gcc to make calls between c and c++ or between c and fortran by using g++ or gfortran, respectively. But if I try to make procedure calls between c++ and fortran I get errors when compiling with either g++ or gfortran because neither knows about the other's required libraries. How can I link a project that uses source code written in both c++ and fortran?I can use gcc to make calls between c and c++ o
