| # You can skip this section if and only if you are not planning to use | |
| # a BLAS library featuring a Fortran 77 interface. Otherwise, it is | |
| # necessary to fill out the F2CDEFS variable with the appropriate | |
| # options. **One and only one** option should be chosen in **each** of | |
| # the 3 following categories: | |
| # | |
| # 1) name space (How C calls a Fortran 77 routine) | |
| # | |
| # -DAdd_ : all lower case and a suffixed underscore (Suns, | |
| # Intel, ...), [default] | |
| # -DNoChange : all lower case (IBM RS6000), | |
| # -DUpCase : all upper case (Cray), | |
| # -DAdd__ : the FORTRAN compiler in use is f2c. | |
| # | |
| # 2) C and Fortran 77 integer mapping | |
| # | |
| # -DF77_INTEGER=int : Fortran 77 INTEGER is a C int, [default] | |
| # -DF77_INTEGER=long : Fortran 77 INTEGER is a C long, | |
| # -DF77_INTEGER=short : Fortran 77 INTEGER is a C short. | |
| # | |
| # 3) Fortran 77 string handling | |
| # | |
| # -DStringSunStyle : The string address is passed at the string loca- | |
| # tion on the stack, and the string length is then | |
| # passed as an F77_INTEGER after all explicit | |
| # stack arguments, [default] | |
| # -DStringStructPtr : The address of a structure is passed by a | |
| # Fortran 77 string, and the structure is of the | |
| # form: struct {char *cp; F77_INTEGER len;}, | |
| # -DStringStructVal : A structure is passed by value for each Fortran | |
| # 77 string, and the structure is of the form: | |
| # struct {char *cp; F77_INTEGER len;}, | |
| # -DStringCrayStyle : Special option for Cray machines, which uses | |
| # Cray fcd (fortran character descriptor) for | |
| # interoperation. | |
