WebMay 7, 2024 · With C, the Fortran standard starting Fortran 2003 (about 18 years go) started providing a way to recognize the companion processor and defined the aspects toward interoperability. And practically, the conforming Fortran processors now strive to also interoperate with a companion C processor. Webuse, intrinsic :: iso_c_binding, only : c_int, c_float type, bind (C) :: goose_t integer (c_int) :: flock real (c_float) :: buoyancy end type goose_t type (goose_t) :: goose_f. Data can now be transferred between goose_c and goose_f. C routines which take arguments of type Goose can be called from Fortran with type (goose_t).

The standalone f2c program was based on the core of the first complete Fortran 77 compiler to be implemented, the "f77" program by Feldman and Weinberger. Because the f77 compiler was itself written in C and relied on a C compiler back end to complete its final compilation step, it and its derivatives like f2c were much more portable than compilers generating machine code directly. hatch toronto office
