Having identified the correct libraries to link to, we need to make sure that our program can correctly call the functions they define. Every compiler performs name mangling when generating machine code and, unfortunately, conventions for this operation are not universal, but compiler-dependent. FortranCInterface, which we have already encountered in Chapter 3, Detecting External Libraries and Programs, Recipe 4, Detecting the BLAS and LAPACK math libraries, checks the compatibility of the selected C compiler with the Fortran compiler. For our current purposes, name mangling is not really an issue. The Fortran 2003 standard defines a bind attribute for functions and subroutines that accepts an optional name argument. If this ...
