In +most cases, use of the C Binding features of the Fortran 2003 and +later standards is sufficient. +</p> +<p>For example, it is possible to mix Fortran code with C++ code as well +as C, if you declare the interface functions as <code>extern "C"</code> on +the C++ side and <code>BIND(C)</code> on the Fortran side, and follow the +rules for interoperability with C. Note that you cannot manipulate +C++ class objects in Fortran or vice versa except as opaque pointers. +</p> +<p>You can use the <code>gfortran</code> command to link both Fortran and +non-Fortran code into the same program, or you can use <code>gcc</code> +or <code>g++</code> if you also add an explicit <samp>-lgfortran</samp> option +to link with the Fortran library.
